Sliding Vane Pumps

Sliding Vane Pumps

Sliding vane pump is a popular pump design for applications requiring flow rates of 75 LPM – 1000 LPM. The sliding vane design combines low cost with high reliability and easy maintenance.

The sliding vane principle is simple. A slotted rotor is supported in a cam. The rotor is placed close to the wall of the cam so a crescent shaped cavity is formed. The clearances are precise and minimal. Vanes, also known as blades, slide in and out of the rotor slots to seal off a volume between the rotor, cam and side plate. The blades sweep the fluid to the opposite side of the crescent where it is squeezed through the discharge point.

Sliding vane pumps can run dry for a short period of time; they also can tolerate small amounts of vapour.

Sliding vane pumps are widely used for low viscosity fluids and for fuel transfer, including LPG, diesel, petrol, biodiesel, liquefied gases as well as for loading and unloading.

Chemical Processing

Pumping chemicals and industrial solvents

Liquefied Gases

Ductile iron, UL-listed pumps for LPG or NH3 transfer applications as well as pumps for liquid CO2.
