PROLUBE Air Operated Double Diaphragm Pump | 1/2-inch Pump Inlet/Outlet | Polypropylene Casing | Teflon (PTFE) Diaphragm | 11.9 GPM | Self Priming | Explosion Proof | Submersible (44721)

PROLUBE 44721 Air Operated Double Diaphragm Pump is driven by compressed air and designed for use in applications requiring large volume transfer In a very short time; No close fitting or Rotating parts so liquid with high solids content and/or size can be easily pumped. Self-priming pump design (incorporating internal check valves) allows for high suction lift even at dry start-up and with heavier fluids; no close fittings or sliding parts are at risk. The pump can run dry without damage.
