Pneumatic Displacement Sump Pumps
The Pitbull pump design eliminates seals, impellers, diaphragms, and internal components to reduce pump maintenance. Two check valves route large solids/liquids through full pipe-diameter passages at low velocities. Pitbull manufactures a full line of these unique, air-operated pumps in flows from 5 to 2000 gallons per minute. Submersible, transfer, self-priming and filter-press feed configurations/models are available in stainless steel and carbon steel construction, as well as other alloys and non-metallics.
