An extended spring on these seals accommodates variations in seal cavity length and pump misalignment.

Narrow-Profile Mechanical Pump
Shaft Seals with Extended Spring

With a smaller seal OD than standards seals, these seals have an extended spring that accommodates variations in seal cavity length.

Mechanical Pump Shaft Seals

These seals are commonly used in well, sump, and displacement pumps.

Mechanical Pump Shaft Seals with Compact Spring

Built for small circulation and dispensing pumps, these seals have short springs.
