PRO (Progressive Cavity Duplex Cartridge Mounted Seals)

SEPCO PRO seals are used in applications on progressive capacity pumps where positive lubrication is required without dilution of the pumped product.

Elliptical Gland: Designed to fit the tight clearances encountered on progressive cavity pumps.

Cartridge Mounted: Cartridge mounted for ease of installation. The seal is preset at the factory and pressure tested prior to shipment.

Stationary Seal Design: This design eliminates spring fatigue and wear in the secondary areas of the seal.

Balanced Design: The seal is balanced to handle higher pressures.This seal can be designed to fit virtually any progressive cavity pump application, including a single cartridge seal.
