Heavy Duty Mechanical Pump Shaft Seals
 |
Multiple internal springs ensure these seals keep the sealing surfaces in contact in demanding applications, such as agricultural, chemical, and mining pumps. Seals come furnished as two pieces—the seal and the seat. The seal is comprised of the case, springs, diaphragm, and washer, and the seat is comprised of the seat and the gasket. Seal Width represents the working height, which is the compressed length when installed.
Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

Cartridge Mechanical Shaft Seals
 |
Install these seals faster and with less technical expertise than other mechanical shaft seals that come in two pieces. They come with their seal and seat already assembled. All have a carbon washer that is self-lubricating. However, this means their washer is too soft to be used with abrasive liquids and liquids with harsh additives.
Fluoroelastomer Diaphragm—Seals with a fluoroelastomer diaphragm can be used with a wider range of chemicals than EPDM diaphragms, including benzene, butyl alcohol, and fuels.
EPDM Diaphragm—Seals with an EPDM diaphragm won’t break down from exposure to water and steam. However, they are for use with fewer chemicals.

PTFE Stackable V-Ring Packing Seals
 |  |
Male and Female Adapters Stacked with Five V-Rings | Profile |
Made of PTFE, these V-ring packing seals have excellent chemical resistance and withstand a wide temperature range of -110° F to 500° F. Stack as many V-rings as you need to fill grooves in valves, pumps, and cylinders.
Begin with a male and female adapter, then add V-rings between them to fill the space. Each V-ring adds to the sealing force; the female adapter also has a sealing edge. For a complete seal, you need male and female adapters (sold together) and at least one V-ring (sold in packs of 5).
Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

Mechanical Pump Shaft Seals
 |
Commonly used in well, sump, and displacement pumps, these seals have a two-piece spring-loaded design that keeps the sealing surfaces in contact as the material wears. Seals come furnished as two pieces—the seal and the seat. The seal is comprised of the case, spring, diaphragm, and washer, which come locked together as one piece. Seal Width represents the working height, which is the compressed length when installed. The seat is comprised of the seat and the gasket.
Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.
Viton® Fluoroelastomer Diaphragm—Viton® fluoroelastomer diaphragms resist a wider range of chemicals than Buna-N.
Viton® Fluoroelastomer Gasket—Viton® fluoroelastomer gaskets resist a wider range of chemicals than Buna-N.
Cannot Be Sold Outside North America—Products cannot be sold outside North America due to restrictions.
