What does a typical repair and refurbishment of a single cartridge mechanical seal look like?
In this new mechanical seal video, GFS Mechanical Seal expert Lino Dimichino, discusses the typical mechanical seal repair and refurbishment process of a cartridge mechanical seal. This important service can help bring new life to your existing mechanical seals without having to purchase a new one.
Many customers of GFS choose to go the route of repair and refurbishment of mechanical seals as opposed to purchasing new ones. It can be more cost effective in many situations, and can make your old seals look just like new.
But what does a repair and refurbishment of a single cartridge mechanical seal look like?

Part 5 - Basics of O-Rings - Intro to Failure Modes
We are excited to present to you part 5 of our O-ring webinar series. For this portion, Benjamin Mell, GFS Application Engineer and Regional Sales Manager, introduces you to O-ring failure modes. Ben will give a general overview of how and why an O-ring might fail, and how you can determine which kind of failure mode the seal experienced.
Then, Ben will dive into the first two O-ring Failure modes.

Part 4 - Basics of O-Rings - O-Ring Profiles
We are excited to present to you part 4 of our O-ring webinar series. For this portion, Benjamin Mell, GFS Application Engineer and Regional Sales Manager, will delve deeper into specific O-ring profiles. While a traditional O-ring has a circular profile, additional O-ring profiles and sub categories have evolved over the years to solve specific application challenges. We are going to review each of these profiles and their benefits.
Part 4 will discuss:
1. Standard O-rings
2. Cord-Rings
3. Quad Rings® / X-Rings
4. Encapsulated O-rings
5. Hollow O-rings

Part 3 - Basics of O-Rings - Core Applications
A static seal is one that remains stationary. And in a truly static seal, the mating gland parts are not subject to relative movement. Most O-ring applications are static.
But what happens when there is relative motion? That's where dynamic seals enter. In this new video webinar, Ben Mell, Regional Sales Manager at Gallagher will discuss reciprocating seals, rotary seals, o-ring design, and common applications to consider throughout the design process.

Cartex® Cartridge Mechanical Seal
EagleBurgmann's Cartex mechanical seal is fully pre-assembled is designed with greater attention to functional details like tighter tolerances for more accurate seal operation, greater axial movement to handle pump shaft movement, seal parts with robust cross sections for optimal seal stability in operation, and castings that meet ASTM A 351/351M standards for proven quality. The seals are installed in pumps in a wide range of industries including chemicals, water supply, paper production, food processing and many other applications. Cartridge seals are easy to fit, and they keep your running costs down.
The Cartex® cartridge seal line now includes single and double seal versions for all standard operating modes as well as special versions. For example: the Cartex range is now applicable for sterile applications or installation in positive displacement pumps.

Elastomers are a high molecular weight polymer that exhibits little plastic flow, and has a rapid recovery from an extending or compressing force. Elastomers are produced naturally as gum rubber on commercial rubber plantations or manufactured synthetically. Today, more than 32 synthetic rubbers are known.
In Part 2 of our webinar series, Benjamin Mell, Regional Sales Manager at Gallagher Fluid Seals will elaborate on the most common types of elastomers used in o-ring applications. He will discuss their performance characteristics, application details, and pros vs. cons.

O-rings are the most common sealing product in the world. An O-ring is a versatile solution that will effectively seal every time, assuming that basic design parameters are followed. It is also an inexpensive sealing solution compared to other products. An O-ring should always be considered for a seal application due to its low price and availability.
This blog and is the first in a multi-part video webinar series on the basics of o-rings.

While O-Rings are an incredibly useful sealing application, they are not infallible. When they fail, it’s usually because of the combined adverse effects of several environmental factors.
The most common causes of O-Ring failures include:
- Improper gland design, allowing for too much or too little compression, not enough for seal expansion and tolerance stack-up.
- Incorrect O-Ring size.
- Incompatibility of O-Ring elastomer and environmental elements.
- Improper O-Ring installation.
- Inadequate O-Ring lubrication.
The combination of stresses on the O-Ring can be complex and difficult to evaluate. Therefore, it is crucial that both the O-Ring compound and size be tested in the real environment of its service. Below you’ll find three examples of the types of O-Ring failure that can occur, what causes the failure and how to identify and correct it.
