Fluid-O-Tech Rotary Vane Pumps | Nespl
The rotary vane pumps Supplier by Nespl for Hydro components & Technologies, Inc. are volumetric pumps designed for pumping water and aggressive liquids with low flow at high pressure.
These increasing-volume vane chambers are filled with fluid forced in by the inlet pressure. Inlet pressure is actually the pressure from the system being pumped, often just the atmosphere. On the discharge side of the pump, the vane chambers are decreasing in volume, forcing fluid out of the pump.
