Z-Model Sliding Vane Pump

The Z-Series Coro-Vane® pumps, the newest line of sliding vane pumps offered by Corken, are designed with our patented needle roller thrust bearing rated for 4,000 lbs. The needle roller thrust bearings protects the pump against dynamic impact loads imposed on the pump by the drive system. Premature failures due to axial thrust loads are minimized on truck applications. They have O-ring construction throughout and are rated for 400 psi (28.6 bar) working pressure. Since the Z-models sliding vane pumps are used primarily in LPG (propane & butane) and agriculturalammonia applications, the non-adjustable internal relief valve is pre-set at the factory.

When the application requirements are suitable, Z-model pumps are a great option for many other liquefied gases with high vapor pressures such as natural gas liquids (NGLs), refrigerants, CO2, and many more. Applications include bulk pump transfer, propane delivery truck and transport. Available in 2”, 2.5”, 3” and 4” sizes.
