3:1 Air Operated Oil Pump - Long Series
The STM DITI1701033 is a 3:1 air-operated oil pump kit designed for transferring lubrication oil, waste oil and antifreeze liquids from 180ā220 kg (400 lb) drums. The 3:1 compression ratio delivers higher outlet pressure from the same air supply compared to 1:1 pumps, making it suitable for more viscous oils up to SAE 150. Operating at 5ā8 bar, it delivers 12 L/min with a 940mm (37") suction tube for extension transfer applications, a 1/4" quick plug air inlet and a 1/2" male oil delivery connection for standard delivery hose connections.
