CORKEN PZ Series

Pumps for petroleum products PZ series – for refined petroleum products and industrial solvents

The Corken PZ series petroleum pumps offer the industry greater flexibility and independence: in the configuration and equipment of fluid transfer systems and fuel delivery tank wagons. The pumps correspond to common industry standards and are easily integrated into already existing or new vehicles.

Viton®¹ O-rings are standard with pumps of the PZ series. Corken’s mechanical seal, fitted with Viton® O-rings is compatible with refined petroleum products including gasoline, fuel oil, kerosene, diesel fuel, AvGas, and others to pump nearly any product you are carrying.

The controlling of thrust load and caviation is decisive for a longer service life. The pumps pf the PZ series are a new generation of vane pumps for fuel transfer that controls heavy thrust loads better than any other truck pump on the market.
The thrust absorbing system of the PZ series pumps is comprised of two needle roller thrust bearings at each shaft extension rated for up to 4,000 lbs. of thrust. This patented design protects the pump from dynamic loads and impact loads that are often imposed on the pump by the drive system. Premature failures due to axial thrust loads are minimised with these thrust absorbing bearings.

A state-of-the-art cam design virtually eliminates cavitation—even while pumping at low tank levels. By eliminating cavitation, the vanes, cam and sideplates remain lubricated and experience less wear. The PZ series also has vanes and vane drivers made of advanced non-metallic composite materials that last longer than ordinary vanes and vane drivers.
