General Information
Principles of the RVP-Series and PS-Series pumps
The RVP-Series and PS-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 PS-Series and 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 RVP-Series and PS-Series pumps
The pumping of volatile liquids is one of the most difficult of all pumping jobs, and pumping from a delivery truck makes t 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, your RVP-Series and PS-Series pumps have a number of other features
to help make them more easily operated and maintained.
