Generator set details
Hydraulic pump
-
Fixed displacement gear pump, 1.5 Gal/min at 2500 psi
-
A generator set with a 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
