Move bulk, hydraulic and used oil without hand pumping
The GROZ 45550 is a heavy-duty 115V gear pump for transferring bulk oils, hydraulic oils and used oil from drums and tanks. It delivers up to 4 GPM (15 LPM) at 65 PSI and handles viscous fluids up to SAE 90, even at low temperatures. It threads straight into a 2" bung and comes ready to use with a suction tube and delivery hose.
Why choose this pump
- Handles thick oil: positive displacement gear pump with a high horsepower-to-flow ratio, rated up to SAE 90.
- Built to last: non-corroding die-cast aluminum body and sintered powder metal gears.
- Protected motor: 1/2 HP air-cooled motor with thermal protection.
- Safety bypass: internal bypass valve prevents damage if pressure gets too high.
- Ready to mount: built-in 2" bung adapter, 2-piece suction tube and 8 ft hose included.
