Blackmer (PSG) delivers industrial positive displacement pumps for viscous, shear-sensitive, and clean/dirty fluid transfer. Their gear-style and sliding-vane designs provide smooth, pulse-reduced flow, strong suction lift, and excellent volumetric efficiency across a wide viscosity range, with wetted options in ductile iron, carbon steel, and stainless steel.

Ideal for oils & lubricants, solvents, polymers, fuels, adhesives, and food-grade liquids, Blackmer PD pumps support jacketed configurations for heat-traced products, multiple seal options, and relief valves for system protection. The result is reliable loading/unloading, transfer, and metering with simplified maintenance and long service life.
