3P Prinz Rotary Vane

These pumps are Positive Displacement Pumps for the transfer of fluids with a wide range of viscosities and are wear-compensating. They are Self Priming and have an High Suction Lift. Their impeller rotates eccentrically to the pump internal body. The fluid that is enclosed between the impeller, the vanes and the body, is pumped forward.

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 more performing in areas with special installation requirements, where maintenance must be kept at its minimum. The careful selection of the material of the Vanes allow a very low friction and minimal wear-out. Generally Rotary Vane pumps series are supplied with motor or moto-variator and mounted on a suitable skid. Rotary Vane Pumps are ideal for pumping low viscosity and volatile, light fluids, however the same pump can be used also for pumping liquids with higher viscosity.

The Pump Body and Rotor are made of Cast Iron and the Vanes are self-lubricating. A range of Mechanical Seals is available for fitting many applications and fluids. The Power Consumption of these Pumps is lower than other Positive Displacement Pumps, thanks to its high speed and light construction.

They are capable of supplying higher flow rate than other pumps at the same comparable size and operating speed. CN Series Pumps are provided with an Internal By-pass for relieving the flow. They can be opened for maintenance without the need of removing the body from the pipeline. These Pumps can be operated by Electric Motor, Diesel Engine, Hydraulic Motor. A Truck-mounted version, PTO Driven, is available.
Please contact 3P Prinz for further info about this pump execution.

CN Series Pumps are used in petrochemical applications like:
- Refineries
- Terminals
- Tank Farms
- Chemical plants
but also in transportation for loading/off-loading:
- Trucks
- Trains
- Ships and Barges

The scope of supply is not limited to the pumps
3P Prinz can supply also:

  1. Skid type base frames or custom skid mounted
  2. Instrumentation
  3. On-skid piping with valves
  4. Control equipment
  5. Auxiliary equipment


Special Executions and Materials
3P Prinz is able to manufacture the entire range of products with special materials for pump wetted parts.
Starting from Cast Iron to Ductile Iron, Carbon Steel, Stainless Steel, Duplex Stainless Steen and Special Alloys for the most corrosive applications. The material selection depends from the service fluid, the temperature and the external environment. Pumps design life is given by the right materials selection.
