The Bucher Standard-Duty Pump Motor is the OEM replacement motor for the full Bucher hydraulic pump line. 12V DC, 2.1 HP, series-wound with class F insulation and an IP54 dust-and-splash rating. If your HPU still pumps fine but the motor sounds rough or won't start under load, this is the direct replacement.
How do I tell if my Bucher pump motor needs replacing?
Two common symptoms. First, motor spins fine unloaded but stalls or hums when the cylinder hits load — usually worn brushes or a tired armature. Second, motor doesn't spin at all but the solenoid clicks and the wiring tests good — usually a stuck or open commutator. Either case, this motor is the OEM-spec replacement.
- 12V DC, 2.1 HP, series-wound (wound field)
- Counter-clockwise rotation
- Class F insulation, IP54 dust and splash resistant
- Standard-duty intermittent rating
- 4.5 in diameter, 6.75 in overall length
- Direct fit on Bucher hydraulic pumps

Issues
The motor doesn't work. I don't think the motor is bad, it seems to be an electrical issue. The armature came out when I had to remove the motor. It looked fine inside. I gave it a five star because I believe the motor is good.
