The Z-Series Coro-Vane® pumps offer a six blade design with blade drivers and a 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. With O-ring construction throughout, they are rated for 400 psi (28.6 bar) working pressure. Since Z-Series sliding vane pumps are used primarily in LPG (propane & butane) and agricultural ammonia applications, the internal relief valve is pre-set at the factory and does not require adjustments in the field.
Z-Series pumps are a great option for 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”, 3” and 4” sizes.
