Description

RVP-Series 
pumps are rotary vane type, self-priming, provided with integral by-pass 
valve to protect the pump and system against overpressure. 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 RVP 
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. Originally 
designed for fuel and light petroleum products applications, SAMPI RVP 
pumps are also available in special executions for industrial and 
chemical products like solvents, resins, inks and so on. Due to its 
efficiency this kind of pump can handle viscous and also volatile 
liquids and requires less horsepower than other equivalent pumps.
