Power Unit Gear Pumps – Pressure Balanced Tang Drive, 1.1 to 8.0 cc

Replacement gear pumps for compact hydraulic power packs – the pressure balanced tang drive pumps fitted to the Mocen-pattern DC and AC power units we sell, plus the petrol power unit pump. The displacement is stamped into your pack code, so matching the pump takes ten seconds.

Ways to buy your pump:

• Off the shelf – eleven displacements below.
• Bigger flows, engine and bell-housing mount pumps live in our gear pump category.
• Motors and solenoids: DC motors, valve solenoids.

How to choose

• The pump cc is in your pack code: a 16DA010H211A runs the 2.1 cc pump (G210).
• Runs but no pressure = pump or relief valve. Whines and foams the oil = suction leak or low oil, not the pump.
• Do not upsize the pump hoping for speed – the motor amps go up with it and an S3 motor cooks.

Technicians Advice

Fitting a pump: wind the relief right out, fill the tank, jog the motor to prime, then set the relief against a gauge – never run a dry gear pump against a dead-head, the first two seconds decide its life. These pumps are handed for the standard power-unit rotation; if you are adapting one to anything else, confirm rotation before bolting it on – run a gear pump backwards and it blows its own shaft seal. If the old pump ate itself, flush the tank and lines and fit a new magnetic drain plug before the new pump goes in, or the swarf finishes the new one inside a week.
