DXP Pacific offers a range of rotary vane and other positive displacement pumps from Blackmer, who have been known for their energy-saving positive displacement sliding vane pump designs. Specifically, the S Series Triple Screw Pumps are positive-displacement rotary pumps meant for handling clear, lubricating liquids that do not have any solid content. They are ideal for handling some of most demanding material, such as slurry, solvents and other viscous products. By providing a smooth constant flow across a wide range of viscosities, pressures and temperatures, these pumps are very efficient, compact, low-noise, self-priming and environmentally friendly.
