Generator set details
Hydraulic pump
- Fixed displacement gear pump, 1.8 Gal/min at 2500 psi
- Hydraulic pump is rated with the pump idle
- When using a non-Cummins Onan pump supplied by
the customer, the hydraulic pump shaft seals must be
capable of operating in a temperature environment of
225° F to 250° F. Seal failure will result in equipment
damage
