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, while also providing a sustained performance and trouble-free operation.
Rotary vane pumps are ideally suited for a wide array of markets, including chemical process, energy, transport, military & marine, general industry, and oil & gas. These positive displacement pumps are designed to handle a range of low- to medium-viscosity fluids, including those at high temperatures, non-lubricating fluids such as alcohols and gasoline, and liquids that contain gas/vapor content or liquids containing suspended solids.
