Positive Displacement Sliding Vane Pumps are highly efficient, self-priming, generally for low to medium viscosity lubricating and non-lubricating liquids. These pumps have a number of vanes that are free to slide into or out of slots in the helical rotor pump. 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. Automatic compensation for vane wear assures the pump will maintain its superior priming characteristics and line-stripping ability over a long service life. Smooth output flow ensures quiet operation within the NPSH range.
The pumps can be direct-coupled to synchronous-speed motors.
