Double Diaphragm Air Pump PII.75A Chemical Industrial Aluminum 3/4" NPT Inlet/Outlet

wrong part and part numbers didn't even match order Poor quality control.

I installed this pump in my auto repair shop to transfer Antifreeze from my portable drain containers to a main tank for disposal. I also installed a debris strainer on the suction intake to keep debris from fouling pump's internal check valve balls & seats. It is working exceptionally well. It moves product rapidly from container to tank and therefore keeping my technicians from waiting on slow ineffective rotary pumps. It has never failed to draw antifreeze quickly up from containers to pump and into tank. I highly recommend this pump for the purposes that I have used it for.

Arrived on time. Works great.
