3:1 High Flow Air Operated Oil Pump - Long Series
The STM DITI1701036 is a 3:1 high ratio air-operated oil pump designed for transferring lubrication oil, waste oil and antifreeze liquids from drums. The 3:1 compression ratio delivers a maximum fluid pressure of 24 bar (348 psi) — significantly higher than standard 1:1 pumps — making it ideal for more viscous oils up to SAE 150. Operating at 5–8 bar, it delivers 28 L/min with a 940mm (37") suction tube for extension transfer applications, a 1/4" quick plug air inlet and a 3/4" male oil delivery connection for high-flow delivery hose connections.

Features
| •3:1 high ratio — delivers up to 24 bar (348 psi) maximum fluid pressure for more viscous oils up to SAE 150 |
| •Air-operated for consistent 28 L/min oil delivery at 5–8 bar operating pressure |
| •940mm suction tube — suited to extension transfer applications directly into drums |
| •Drum compatible — fits commercial drums with 57mm diameter hole and 2" BSP threading |
| •1/4" quick plug air inlet (also accepts 1/4" NPT female) for fast connection to compressed air supply |
| •3/4" male oil delivery connection — suits standard 3/4" delivery hoses per DIN-SAE norms |
| •Suitable for lubrication oil, waste oil and antifreeze liquids — not suitable for any other substance |
Compressed air must be filtered to avoid dust and moisture entering the pump. Max compressed air pressure must not exceed 0.8 MPa / 120 psi. Always cut off the air supply after use. Use only for lubricants, waste oil or antifreeze liquids.
