Vesconite Hilube Wear Rings Save Money for Pump OEM

Vesconite Hilube Saves Energy Costs for Pump OEM

The installation of Vesconite Hilube wear rings can result in electricity savings that more-than-pay for the wear ring.

picture of hilube wear ringsThis was the result of a study by a large pump original equipment manufacturer (OEM) that compared energy usage on a typical submersible pump when Vesconite Hilube wear rings were in place versus stainless steel wear rings that had been previously installed.

Vesconite Hilube is a low-friction wear-resistant polymer. Wear rings made from the material are designed to seal the pressure leakage of the liquid between the inlet and the impeller and the pump casing, and should result in a higher pumping efficiency due to lower by-pass.

Vesconite Bearing technical pump consultant Phillip de Villiers was pleased when the pump OEM’s results independently proved Vesconite Hilube’s ability to improve pumping efficiency and decrease electricity usage.

The study showed a 0.11kW/h energy reduction when operation of the pump with a large diameter stainless steel wear was compared with operation of the same pump type with a dimensionally-identical Vesconite Hilube wear ring.

Assuming the Vesconite Hilube wear rings use on an industrial pump, operating 24 hours a day, 365 days a year, the electricity savings from installing a Vesconite Hilube wear ring add up, particularly when the pump is operated in a jurisdictions in which electricity charges are high.

In the specific pump that was studied by the OEM, the wear ring would have a three-month payback even where a low electricity cost was assumed, notes De Villiers.

He adds that electricity savings for a five-to-ten stage submersible pump can be significant if the electricity savings of each stage are added together.

With concerns about global CO2 emissions from electricity generation – which reached 12Gt in 2010 – as well as an awareness that pumps account for 10% of global electrical energy consumption, technological interventions are valued by pump manufacturers and pump users.

They are also of interest to state and national governments that are interested in reducing carbon emissions to keep global warming under 1.5°C.

Self-lubricating Composite Wear Rings

Composite Wear RingsCIP Composites are laminated polymer materials made by impregnating textiles with thermoset resins. Solid lubricants are added to the resin to provide evenly dispersed lubrication throughout the material, providing smooth operation.

CIP custom composite wear rings are a superior alternative to commonly used cotton phenolic and glass filled nylon materials. They allow smooth operation and high side loads while protecting the sealing elements and preventing metal to metal contact in hydraulic cylinders. CIP wear rings are preferred where high performance, large diameters and/or high temperatures are required.

CIP Composite wear rings provide manufacturers and servicers alike with solutions to reduce overall maintenance and increase wear life. CIP offers short lead times, reducing the costs associated with equipment downtime and repairs. CIP Composites are manufactured in the United States using only the highest quality materials.

CIP Composites for Industrial Applications

Industrial applications can be found in many industries and range from hydraulic cylinders to heavy duty equipment. Many industrial applications are in harsh environments including dirt and mud, chemicals, a range of temperatures, and hard to reach locations, making maintenance a challenge. Equipment down time for maintenance and repairs can be detrimental to the industry.

CIP Composites offers solutions for rigorous industrial applications by extending wear life while reducing or eliminating external lubricants and undesired maintenance. As a general guide, CIP Composite bushing materials can replace your current bronze or nylon based wear and bearing materials. Sold in tubes or sheets for easy machining onsite, or custom manufactured with short lead times.

Hydraulic & Pneumatic

Hydraulic cylinders are the ideal choice for a host of mobile and industrial applications where power and reliability, along with low operating costs are required. Hydraulic (and even pneumatic and electrical actuator) cylinders are handling more demanding applications than in previous years, such as the use of smaller cylinders which force higher and higher operating pressures. Manufacturers and servicers alike depend on quality components to ensure that their finished product meet or exceeds the customer requirements including long service life, affordability, and availability.
