It pumps
Works as should

Moves a lot of volume
Diaphragm pumps are great for semi thick fluids like asphalt sealer. This pump is easy to plumb to your air compressor to transfer fluid easily. The only drawback to an air operated diaphragm pump is the surging as each side pumps, with a closed system like a seal coating truck this isnโt very noticible. This pump moves product effortlessly.

Extremely slow
Bought to pump used oil out of 250g IBC tote into tank for waste oil heater. Took 1 hr to pump 150 gallons. Shop compressor is rated for 40cfm @ 140 psi. 1/2" pipe from compressor to Milton type G connector (1/2" connector). 3/8" hose 3' long from connector into pump. It is soooo slow.
