Corken : Z / PZ / PT Petroleum Pump

For refined petroleum products and industrial solvents

The Corken PZ-Series petroleum pumps offer the industry a choice in pump brand for greater flexibility and independence in the configuration and outfitting of fluid transfer systems and fuel delivery tankwagons. The pumps match common industry-standard flange-to-flange and mounting footprint dimensions for easy incorporation into existing or new vehicle layouts.  And, they provide features that will be appreciated by system designers, truck outfitters, and end-user fuel marketers.

The PZ-Series Corken pumps are a new generation of vane pump 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 pump 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 and impact loads 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 nonmetallic composite materials that last longer than ordinary vanes and vane drivers. This combination of innovative cam and thrust bearing design makes the PZ-Series a smart choice for anyone wanting improved performance and longer service life with exceptional reliability.
