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.

Fixed Clearance Flows for 08111 Motor

Flows are for bled-to-reservoir pumps. Bled-to-suction pumps will provide lower flows and have lower pressure limits. Values shown are in gpm.
