Pressure Pumps
The Sterlitech line of pressure filtration pumps and accessories includes our Gast continuous filtration pump, our popular Rocker vacuum filtration pump, and our stainless steel Rocker 440 air compressor. As an added benefit, the Gast filtration pump can also be used as a positive pressure filtration pump. The Rocker vacuum filtration pump includes a vacuum to pressure conversion kit.
