 PZ-Series Coro-Vane® Petroleum Pumps
The PZ-Series Coro-Vane® Petroleum pumps are a positive displacement vane design. They produce a maximum differential pressure of 125 psig (8.6 bar) and a maximum working pressure of 200 psi (13.8 bar). Corken manufactures two sizes of PZ-Series Coro-VaneÒ pumps with a capacity up to 160 gpm (605 L/min). Applications
Typical applications for the PZ-Series Coro-Vane® pumps include fuel oil delivery trucks and stationary applications involving refined petroleum products and industrial solvents.
Highly reliable
mechanical seals are
easilty replaced. | Low-impact high strength vane driver and vane design extend pump life. | |
Precision-machined sideplates are reversible for extended life. | | Manually adjustable internal bypass valve (standard bypass valve shown) or optional Air Operated Valve (AOV) available for high flow and low flow control. |
Innovative needle
roller thrust bearing
design controls heavy
thrust loads. | | |
Conveniently located
pump drain allows you
to easily remove
residual fluids when
performing system
maintenance. |  
Flanges available in NPT,
Weld, and BSPT designs. | | | | High flow inlet design virtually eliminates cavitation, enhancing pump deliver and increasing pump life. |
| Features and Benefits | | • | Bundled Packages Available: Includes a Corken pump and Liquid Controls meter and register for assured system compatibility.
| | • | Flange to Flange “Bolt-In” Replacement for Other Truck Pumps: Simplifies retrofit installations on most fuel oil trucks.
| | • | Nonmetallic Vane Driver Design: Does not penetrate or damage the vane even at high RPM.
| | • | Reversible Sideplates: Corken’s sideplates are designed to be used on both sides which extends the service life of the pump.
| | • | Maintenance Made Simple: By removing only eight bolts, you have easy access to the sideplate, mechanical seal, and vanes.
| | • | Conveniently Located Drain Plug: Enables you to easily remove residual fluids before performing system maintenance.
| | • | Ductile Iron Construction: Provides superior mechanical properties for the pump casing and heads.
| | • | Two Bypass Options: For mobile applications, the pump is equipped with a standard bypass valve or an Air Operated Valve (AOV) for high and low flow control. |
Mounting Options
The PZ-Series is currently available with two mounting options: belt drive for stationary applications and hydraulic drive for mobile transfer applications. The PZ-Series are designed to run up to 800 RPM. Multi-Product Package Offering
As part of our continuous effort to expand into new markets, Corken has teamed up with Liquid Controls, a specialist in fluid measurement, to offer a new line of PZ-Series Coro-Vane® (rotary vane) pumps for petroleum tank wagons. Liquid Controls strong presence in the petroleum market provides Corken with a tremendous opportunity for growth. The Liquid Controls meter and electronic register, combined with the superior performance of Corken’s new PZ-Series petroleum pump can now be specified from participating distributors and truck builders. |
