Coro-Vane® Truck Pumps
The Z-Series Coro-Vane® truck pumps are specifically designed to perform in such severe operating conditions as high differential pressure, pump overspeeding, poor suction conditions and heavy thrust loads associated with a power take-off (PTO) drive system.
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-Vane® pumps with a capacity up to 160 gpm (605 L/min).
PT-Series Petroleum Pumps
The PT-Series pumps are a special type of rotary positive displacement pump, known as a sliding vane pump. The sliding vane pump has many of the positive displacement advantages of the gear pump, plus the ability to compensate for wear, and operate at a lower noise level. The sliding vane pump consists of a rotor turning inside a cam that is machined eccentrically in relation to the rotor. As the rotor turns, the liquid that is trapped between the rotor, cam and vanes is displaced. The PT-Series pumps are made with vanes
produced from advanced polymers which exhibit extremely low coefficients of friction. The self adjusting vanes compensate for wear and help extend the life of the pump.
