3P Prinz Rotary vane pumps are Positive Displacement Pumps for the transfer of fluids with a wide range of viscosities. The pump are wear-compensating which gives low ongoing costs and a long service life. The pumps are self priming and have a high suction lift. The impeller rotates eccentrically to the pump internal body & the fluid that is enclosed between the impeller, the vanes and the body, is pumped forward.
3P Prinz Rotary Vane Pumps (CN series)
General
Thanks to the self-adjustment feature of the vanes, wear out is compensated, increasing the pump lifetime. 3P Prinz CN Series Pumps are designed and made with special technical and patented innovations, in order to make them perform well in areas with special installation requirements, where maintenance and ongoing costs must be kept to a minimum. The careful selection of the material of the Vanes allow a very low friction and minimal wear (increasing the life of the pump). Generally Rotary Vane pumps are supplied with motor (motor can be with or without a variable speed drive) and mounted on a suitable base plate. Rotary Vane pumps are ideal for pumping low viscosity and volatile light fluids, however the pump can also be used also for pumping liquids with higher viscosities.
The pump body and rotor are made of cast iron and the vanes are self-lubricating. A range of mechanical seals & other sealing options are available for suiting a wide range of applications and fluids. The power consumption of these pumps is lower than other positive displacement pumps, thanks to its high speed, light construction & efficient design.
3P Prinz Rotary Vane pumps are capable of supplying higher flow rates than other pumps at the same comparable size and operating speed. CN Series pumps are provided with an Internal safety pressure relief valve. They can be opened for maintenance without the need of removing the body from the pipe work. These pumps can be operated by electric motor, diesel Engine, hydraulic motor or a truck-mounted version, PTO Driven, is available.
