Corken - PT20 - Coro-Vane® PTO Pump

The model PT20 is a 2 inch petroleum pump and is ideal for ?lube Oil deliveries that require low flow rates. Applications include deliveries to service centers such as auto dealerships and quick lube companies.

Principles of the PT-Series 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.

Exclusive Features of the PT-Series Pumps
The pumping of volatile liquids is one of the most difficult of all pumping jobs, and pumping from a delivery truck makes it even more difficult, so more attention must be given to the design and manufacturing of the pump and to its installation and operation. In addition to being especially suited for handling volatile liquids, the PT-Series pumps have a number of other features to help make them more easily operated and maintained.
