Pompe 3P Rotary Vane Pumps

CN Series – Rotary Vane Pumps

The CN Series Rotary Vane 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.

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.

They are capable of supplying higher flow rate than other pumps at the same comparable size and operating speed.

The Power Consumption of these Pumps is lower than other Positive Displacement Pumps, thanks to its high speed and light construction.

Principle of operation:

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.

CN Series –Materials of Construction

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.

Vanes are available in several Materials that fit the fluid application.

Special Executions are available, starting from Cast Iron to Ductile Iron, Carbon Steel,

Stainless Steel, Duplex Stainless Steel and Special Alloys for the most corrosive applications.

CN Series Pumps are provided with an Internal By-pass for relieving the flow.

Generally Rotary Vane pumps series are supplied with motor or moto-variator and mounted on a suitable skid.


These Pumps can be operated by:

- Electric Motor

- Diesel Engine

- Hydraulic Motor

- Truck-mounted version, PTO Driven

Pompe 3P Rotary Vane Pumps Applications

CN Series –Main Applications

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

Pompe 3P®Rotary Vane Pumps Performances

Viscosity Range:

Minimum 0,3 cSt

Maximum 5000 cSt

(maximum recommended500 cSt)

For higher viscosities, a different Vane material shall be selected.

Asper 3P Prinz Experience, for viscosities500 c Stand higher, the Hollow Disk Pump is cheaper and more long-lasting than the Rotary Vane Pump
