How to Fight Leakage & Bearing Contamination with the Right Sealing Solution

Consider mechanical seals, gland packed seals, and lip seals.

The drive for operational efficiency, optimization of assets, and adherence to the International Standards Organization (ISO) 14001 Standard for environmental management systems and ISO-50001 standard for energy management systems must always be balanced against the bottom line.

However, it is fair to say in some cases this can lead to short-sightedness when it comes to selecting sealing solutions, with lower cost at point-of-purchase taking precedence over total cost of ownership.

Mechanical seals have been on the market for around 80 years, and while pump design has remained largely unaltered, sealing technology has evolved over time. This has resulted in advances in reliability, operational efficiency, and environmental sustainability.

Traditional sealing options like gland packed seals and lip seals are traditional for a reason. These products are comparatively inexpensive when taking the purchase price into account, and work well in many applications. This article will take a look at the differences between mechanical seals, gland packed seals and lip seals.

Excessive Wear

Leakage, product loss and bearing contamination that leads to premature failure are three common issues with traditional seals.

There is no reason why bearings should not last for their full predicted lifespan, which is typically calculated at roughly 15,250 operational hours. Leakage caused by inefficient sealing is the simple reason why they do not last. With research showing that water contamination of just 0.002 percent—a single drop—in a bearings chamber can reduce bearing life by almost half, it is easy to see why bearing failure is one of the most frequent causes of pump malfunction. The cost of regularly replacing damaged seals and bearings accumulates over time and can escalate if the pump shaft suffers wear damage and must be repaired or replaced.

Another key cost, which is often overlooked, is the number of hours demanded to maintain, repair and replace these components. Continue reading How to Fight Leakage & Bearing Contamination with the Right Sealing Solution

RoTechBooster Case Study: Clean Gas Despite Fluctuating Operating Conditions

The “Dock Sud“ combined power cycle plant in Buenos Aires, Argentina, is designed to adjust the power generation to the fluctuating electrical demand throughout all seasons. Managing the high demand during the summer months is particularly challenging, and the requirements for system component reliability are correspondingly high.

dock-sud-power-station

The power plant uses diesel engines and gas turbines to drive the generators. The diesel-driven generators run on a regular basis. The gas turbines are operated in start/stop mode so that they can respond quickly to high energy requirements or cope with peak loads.

As a low-pressure gas supply for the plant was only available to use for the gas turbines, a MAN Diesel & Turbo four-stage geared compressor with dry gas seals provided the means to increase gas pressure to the appropriate level for them. There is one geared compressor for each of the two gas turbines on site. Another geared compressor is used as back-up. Due to the nature of the operation, the turbines stop and start frequently placing the geared compressors in a pressurized stand-by mode when electrical demand drops.

Compressor Seals: The Espey™ WKA250ND

Espey chamber seals have a modular design which means the seals can be composed using standard parts to meet individual application requirements. Espey chamber seals work with a very small operation gap between shaft and seal ring – leading to very low leakage – and are designed for dry-running and compensate radial and axial shaft deflections. Another advantage is that no sealing components which could generate additional shaft vibrations are actually fitted on the shaft. The seal rings are axially spring-loaded to prevent swinging up at pressure-less machine operation.

Espey chamber seals are applied in several turbo machines: integral gear, screw and chiller compressors, steam turbines, and shut-off valves for power plants. The main industries in which it is implemented are oil and gas, refining, chemical and petrochemical industry, power plants, and plants for iron and steel production. A further industry field with several references and successes is carbon dioxide capture and storage (CCS). So, what might a success story look like? Check out this WKA 802 HD mechanical seal for a multi-stage integral-gear compressor:

Espey Application Story

Espey™ WKA 802 HD as sealing for a multi-stage integral-gear compressor in a fertilizer production facility.

Client’s Issue

Urea is the worldwide leader in nitrogen fertilizer production. Urea is produced via high pressure synthesis from liquid ammonia and a gas-water mixture with 88.7 % carbon dioxide under high pressure and elevated temperatures in a synthesis tower. Thereby synthetic ammonia carbamate is produced, which is finally obtained as white granules under supply of acid and heat. The high pressure processes are generated by multi-stage radial integrally geared compressors. The seal has to work as leakage protection of the highly-compressed CO2.

The Espey Solution

turbo compressorEspey developed the compact chamber seal Espey™ WKA 802 HD with barrier gas and leakage port and up to 8 seal rings for this radial integrally geared compressor (which was designed by MAN Diesel & Turbo SE). The operation pressure of 140 bar (2031 PSI), the temperature of 225 °C (437 °F) and revolutions up to 40,000 min-1 were the main design parameters. Each of the 8 stages was equipped with an individual Espey ™ WKA 802 HD with different installation lengths, seal, and outer diameters. The one-piece seal rings with titanium bandage were designed axially spring-loaded to avoid vibrations during start and spin-out phase.

The Espey Result

The seal solution has been highly reliable and routinely operates maintenance-free, helping to maximize production.

DiamondFace by EagleBurgmann – Innovative Sealing Technology

What is DiamondFace Technology?

DiamondFace is an innovative microcrystalline diamond coating for mechanical seals. It is extremely hard and offers high wear protection, excellent heat conductivity, maximum chemical resistance and low friction. The coating adhesion also exceeds all known practical requirements. This increases the service life of mechanical seals several times over, the maintenance intervals are extended accordingly and the life cycle costs are greatly reduced.

DiamondFace Technology BenefitThe diamond thin-layer technology was developed in 2007 by EagleBurgmann together with the Fraunhofer Institute for Surface Engineering and Thin Films (IST), the Fraunhofer Institute for Ceramic Technologies and Systems (IKTS), Fraunhofer Institute for Mechanics of Materials (IWM), the Condias GmbH, and the Forschungszentrum Jülich. EagleBurgmann has established DiamondFace for mechanical seals as a series-produced product – the very first on the market.

The technology behind it is a microcrystalline diamond layer up to 15 μm thick which is applied to the seal face under vacuum at temperatures of 2,000 °C (3,632 °F) by chemical vapor deposition (CVD). The properties of this diamond layer are where you benefit. Primarily from its extreme hardness and robustness.

Increased Service Life of Mechanical Seals
Mechanical seals are a factor that has a decisive effect on the cost-effectiveness of your operation because their wear determines the productivity of the entire system, whether it is a pump, agitator or compressor. What causes damage to the seal faces? One reason is dry running which is often unavoidable due to insufficient lubrication or when gas-lubricated seal faces get in contact. The resulting temperature rise causes the seal to wear. And ultimately results in system downtimes.

EagleBurgmann has solved this problem which directly affects the success of your plant. Thanks to DiamondFace, the service life of mechanical seals is increased several times over, the maintenance intervals are extended accordingly and the life cycle costs are greatly reduced. The advantages for the operator are clear: Continue reading DiamondFace by EagleBurgmann – Innovative Sealing Technology

EagleBurgmann Shaft Seals in Waste Paper Treatment

Waste paper treatment is of great significance in the paper industry. The collected and sorted waste paper is fiberized in pulpers using large amounts of water with the addition of chemicals and is sorted into slightly and heavily contaminated fractions.

In the de-inking process, the printing ink is removed by means of chemicals and mechanical forces and is skimmed as foam from the surface in the subsequent flotation.

The risk of dry running for the mechanical seal is especially great for the machines used in the flotation process. The seals in the coarse screening are subjected to intense stress due to the contaminations inclined to plaiting. Know-how and experience in the selection of seals and materials are requirements in order to ensure optimal and trouble-free operation.

The shafts of bleaching agent pumps, MC pumps, dispersers, slurry pumps, sorters, pulpers and fiberizers are successfully equipped with EagleBurgmann single and double seals of the LP, M7N, M74, HR and Cartex-DN series. Thermoflon and Buramex type compression packings reliably seal bleaching agent pumps and separators in the waste paper treatment process.

The New Generation of Elastomer Bellows Seals: eMG and eMG1

Innovation in Detail: eMG and eMG1

Picture of eMG and eMG1With the latest generation of pump seals, eMG1 and eMG, EagleBurgmann has launched a further development of the million-fold proven MG1 on the market which can be used to seal, among other things, chemical pumps, water and waste water pumps, circulating pumps, and submersible motor pumps in numerous industrial sectors.

The eMG1 is 100 % compatible with the well-known MG1 standard seal. It has been innovated in detail and functionally expanded. The optimized geometry of this elastomer bellows seal was tested in long-term applications on EagleBurgmann test facilities and in practical use. A vastly reduced outer diameter of the bellows support now allows direct support by a retaining ring or with the use of much smaller spacer rings. The optimized bellows shape improves the automatic alignment of the bellows on the shaft and minimizes stick-slip effects. The characteristic innovative element is the profiled PEEK-PTFE disk which ensures consistent centering across the entire pressure operating range, exhibits outstanding sliding properties and safeguards the automatic alignment of the elastomer bellows in operation through continuous self-cleaning. The eMG1 is available in numerous material combinations. The program now includes the new face material eSiC-Q7, a powerful silicon carbide optimized towards friction and wear with hydrodynamic properties.

The eMG is identical in construction with the eMG1, but has a 20 % shorter installation length. This provides manufacturers with new opportunities in pump construction: e.g., a more compact design due to shorter shafts with the associated material savings and increased efficiency. The rotating unit is extremely space-saving. The computed pre-modelled bellows design and the spring assembly have no excess lengths and the outer diameter of the bellows support was reduced to a minimum. The standard stationary seat of the eMG is also the short-installation type G6 ring. Synthetic resin impregnated carbon graphite) (B) and the optimized silicon carbide eSIC-Q7 are the standard materials.

Features of the eMG1and eMG1:

  • For plain shafts
  • Elastomer bellows rotating
  • Unbalanced
  • Independent of direction of rotation
  • Single and dual seal

Advantages at a glance:

  • 100 % compatible with MG1 (eMG1)
  • 20 % shorter installation length (eMG)
  • Smaller outer diameter of bellows support enables direct retaining ring support, or smaller spacer rings
  • Optimal alignment characteristic through self-cleaning of disk/shaft
  • Improved centering across entire pressure operating range
  • Special bellows design protects the shaft across the entire seal length and the seal face during assembly
  • Dimensional adjustments and additional stationary seat geometries possible
Innovative face material: eSiC

The eMG1 and eMG can be supplied in numerous material combinations. The program now includes the new optimized face material eSic-Q7 series. A powerful face material optimized towards friction and wear with hydrodynamic properties.

In practice this means up to 50 % longer operating periods, expanded emergency running properties and reduced power consumption. Long-term tests performed at the customer‘s site confirm the efficiency.

picture of emg1 bellows sealThe Compatible One: eMG1

The latest eMG1 generation sets new standards again: an optimized seal design and innovative details guarantee maximum safety and reliability.

The new eMG1 is 100 % compatible with the proven MG1 and can be replaced one-to-one. This permits immediate use of all the advantages. Customized dimensional adjustments and additional stationary seat geometries are possible as option.

The Compact One: eMG

picture of emg bellows seal

The new eMG is unbeatable when it comes to compact seal installation spaces of pumps with consistent requirements. Even with a reduced installation length of 20 %, it has the same technical features as the eMG1.

The short installation length also opens new perspectives in the construction of new pumps. Standard seat of the eMG is type G6 – also very short in lengths.

Customized dimensional adjustments and additional stationary seat geometries are possible as option.

Operating range

  • Shaft diameter: d1 = 15 … 100 mm (0.59″ … 3.94″)
  • Pressure: p1 = 16 bar (230 PSI), vacuum … 0.5 bar (7.25 PSI), up to 1 bar (14.5 PSI) with seat locking
  • Temperature: t = -20 °C … +140 °C (-4 °F … +284 °F)
  • Sliding velocity: vg = 10 m/s (33 ft/s)
  • Admissible axial movement: ±2.0 mm

Upgrade from Pump Packing to Mechanical Seals

Mechanical sealing conserves water, improves energy efficiency, and minimizes environmental impact

The environmental performance of products and processes in all industrial sectors increasingly is cause for critical inspection, with sustainability, conservation of natural resources, and reduced environmental contamination concerns influencing equipment design and selection.

Many industrial processes can be addressed to improve sustainability and minimize environmental impact, while at the same time maintaining or reducing operating costs. Implementing energy-efficient and environmentally friendly processes and technologies should be embraced as a priority at the component, process, and system levels.

One aspect of these processes is mission-critical rotating equipment, and specifically centrifugal pumps, which represent a significant proportion of the equipment found in industrial operations. One vital component of a centrifugal pump is the seal around the rotating shaft that passes through a stationary pressure casing or housing. The seal contains the liquid or gas from escaping to the environment.

Sealing systems help maintain acceptable pump efficiency, reliability, energy consumption, water usage, and emissions control. These factors can materially facilitate achieving total-life cycle cost-reduction and sustainability objectives. Sealing performance can be improved for centrifugal pump applications by upgrading from traditional compression packing to mechanical seal technology.

When sealing a centrifugal pump, the objective is to allow the rotating shaft to enter the wet area of the pump without large volumes of pressurized fluid escaping. The pump discharge pressure forces the fluid back behind the impeller, where it is induced to exit by way of the rotating drive shaft. To minimize leakage, a seal is needed between the shaft and pump housing to contain the pressure of the process being pumped and withstand friction caused by shaft rotation.

Compression packing is the traditional means to seal centrifugal pumps, going back more than 100 years. Also referred to as gland packing, it is a braided, rope-like, and lubricated material packed around the shaft in rings, physically stuffing the gap between the shaft and the pump housing, within a stuffing box.

Water leakage and consumption

Charred packingFor compression packing to work, some leakage must be maintained to lubricate and cool the packing material. Therefore, packing rings allow for an adjustable, close-clearance leak path parallel to the shaft axis. As the packing is used, however, some of the lubricant that is embedded into the packing is lost, reducing the packing ring’s volume. The pressure squeezing the rings together is also reduced, increasing leakage.

Periodic adjustment of the packing follower brings the pressure back into specification and controls the excess leakage. In today’s world, however, this maintenance is not always being done at required intervals or adjusted correctly. As the number of centrifugal pumps incorporating the use of compression packing decreases, training for and understanding of packing maintenance has waned.

Consequently, under-tightening and over-tightening of packing rings is a prevalent and growing misapplication of centrifugal pump maintenance, with critical consequences to both water consumption and energy draw.

Under-tightening results in too much leakage. Already, when properly adjusted, packing leakage can amount to gallons of liquid leaked per minute. This can be either aqueous solutions comprised of varied benign or caustic chemical compositions, or particles in suspension or slurry, depending on the process.

The heavier the suspension or slurry content in the pumped liquid, the more water is needed to get packing to work reliably. Typically, a clean external flush is piped into the stuffing box through a lantern ring, which keeps the packing lubricated and cool while flushing abrasives and chemicals.

Normally, some portion of the leakage is released continually into the atmosphere. Under-tightening of the packing rings and use of external flushes increase this atmospheric release proportionately, along with environmental impact potential.

Case Study: A Single Mechanical Seal, But Twice As Safe Under High Pressure

Mechanical Seal SHVI and Plan 66A for Unmanned Pump Station of an Oil Pipeline

A well-known Canadian operator of an oil pipeline commissioned EagleBurgmann to develop a sealing solution for crude oil pumps. The requirement: It needed to be a single seal that was just as safe as a double seal with buffer pressure system. In addition, the sealing solution was not to be designed for only one pump type but should be installed in various pumps of one station.

SHVI Operating Conditions

The operating parameters were quite extensive: The seal needed to be suitable for a pressure range from 2.5 bar (36 PSI) to 99 bar (1,436 PSI) as well as for shaft diameters from 115 mm to 155 mm (4.53’’ to 6.10’’). Since the pump stations are operated unmanned, the seal must operate without an additional supply system. To protect the environment and personnel, however, the seal housing must not leak if the seal fails unexpectedly.

The solution: Mechanical seal SHVI from EagleBurgmann

These requirements were best met by the SHV series which has proven itself thousands of times over in crude oil pumps and MOL pumps (MOL: Main Oil Line) of all types worldwide for many years. For the Canadian customer, EagleBurgmann developed the SHVI sealing variant with loosely inserted seal face specifically for the high-pressure range. The seal face is single, but is twice as safe under high pressure and is designed such that it always builds a parallel sealing gap with the stationary seat. The deformation behavior of the seal  face was optimized for use in crude oil pumps so that the seal operates reliably even under very high pressures, sliding velocities and temperatures as well as pressure and temperature fluctuations.

Silicon CarbideEagleBurgmann selected a special quality of the silicon carbide material to be used in the pumps of the pipeline operator. This provides the seal face with particularly good emergency running properties and tolerance for partial dry running. In addition, the sliding faces have extremely precisely ground grooves which allow the seal face to be lifted quickly even in the low pressure range and contribute to stable operation in a wide pressure range.

Safety: Optimized API Plan 66A

Plan 66A, which has been available since introduction of API 682 4th Edition, was the obvious choice for the safety concept. Accordingly, the seal housing contains two throttles, and the seal chamber is connected to a pressure transmitter.

SHVI PipelineEagleBurgmann optimized the plan and uses a special inner, floating  throttle. This can withstand a product pressure of 99 bar (1,440 PSI) in an emergency. The pressure transmitter detects pressure changes in the seal chamber and signals an alarm if certain values are exceeded. At the same time, the seal leakage accumulated under low pressure is discharged to a central collection system in the pump station.

Test and Acceptance

The SHVI seal and the optimized Plan 66A were subjected to dynamic and static tests individually and together on EagleBurgmann test benches. The constant and reliable sealing performance in all operating states and the safe function of Plan 66A in the event of a fault provided impressive results. The required system safety was provided at all times.

The new concept of the SHVI single seal with optimized Plan 66A is economical, modular, reliable in operation, and offers the safety of a double seal.

There are plans to convert further pumps of the pipeline operator. The new concept of the SHVI single seal with optimized Plan 66A is economical, modular, reliable in operation and offers the safety of a double seal. For other customers as well, this type of seal has since proven itself in MOL pumps for several thousand operating hours.
