Drive Pump

The drive pump is a bi-directional variable
displacement piston pump. The pump output is
controlled by the electronic displacement controller
(EDC), located on the pump. The only adjustment
that can be made to the pump is the neutral or null
adjustment. Any internal service to the pump
should be performed at an authorized
Sauer-Danfoss service center. Contact Genie
Product Support to locate your local authorized
service center.
