Rotary Vane Pumps

Robert Blackmer revolutionized the pumping industry in 1899 when he invented the positive displacement (PD) rotary vane pump. Featuring unique sliding vane pump technology, this revolutionary rotary vane pump design allows the pump to self-adjust for wear to help maintain flow rates. This design results in a variety of operational enhancements such as excellent self-priming and dry run capabilities.

As a leading global provider of innovative, high-quality rotary vane pump technologies, Blackmer® offers a wide range of solutions from rotary vane hand pumps and stainless-steel vane pumps to magnetic drive pumps and bronze pumps for the military. The Blackmer reputation for unparalleled product performance, innovation, and a commitment to total customer satisfaction has led to an expansive product breath of sliding vane pumps options.

Mouvex® Sliding (Rotary) Vane 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, 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 chambers) when they pass the suction port. The 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.

Ebsray® V Series Rotary Vane Pumps are highly efficient, self-priming pumps for low to medium viscosity lubricating and non-lubricating liquids. These vane pumps are ideally suited for the transfer of LPG, propane, butane and DME, and have been specifically designed and precision built to optimize all the advantages of the sliding vane principle. The V Series Rotary Vane Pump automatically self-compensates for vane wear to ensure the pump will maintain its superior vapor handling and operational efficiency over a long service life.
