This Suntec A2RA 7740 Waste Oil Pump & Motor Assembly with filter is in good used condition. We have tested it rigorously; we test all our pumps with thin diesel fuel, not heavy motor oil; they are pressure and vacuum tested to make sure they pass inspection; the output pressure is tested to make sure it's 40 psi and must have a good flow; we also pressure and vacuum test the shaft seal and run the pump with the inlet side closed off to make sure it will pull down to a minimum of 20 inches of vacuum; many used pumps in the industry do not pass this test at all; we've tested lots of pumps---we know. Only good quality pumps pass this test. We also check to make sure they run quietly. We also oil the pump motor bushings and check the drive coupling to be sure everything is correct and tight as applicable.
