Product Description

These pumps have a number of vanes that are free to slide into or out of slots in the pump rotor.


When the pump driver turns the rotor, centrifugal force, push rods, and/or pressurized fluid causes the vanes to move outward in their slots and bear against the inner bore of the pump casing forming pumping chambers.


As the rotor revolves, fluid flows into the area between the vanes (pumping cambers) when they pass the suction port. This fluid is transported around the pump casing until the discharge port is reached. At this point the fluid is squeezed out into the discharge piping.


Designed for use in refineries, lube oil plants and general industry for processing, filling and transfer applications.


The pump line features replaceable casing liners and end discs that allow easy rebuilding of the pumping chamber to like-new condition without removing the pump from the piping.



Ductile iron construction with internal relief valve.

Unique sliding-vane pump design self-adjusts for wear to maintain flow rates.

Excellent self-priming and dry run capabilities.

Mechanical seal and ball bearing construction provide maximum reliability

Symmetrical bearing support assures even loading and wear for long life.

Adjustable relief valve protects pump against excessive pressures.

External ball bearings are isolated from pumpage by mechanical seals to maximize bearing life and minimize contamination risk.

Easy maintenance: vanes can be easily replaced without removing the pump from the piping system.
