LOAD SENSE PISTON PUMP (219-2426) NOMENCLATURE (CONTINUED)
LOAD SENSE PISTON PUMP (219-2426) COMPENSATOR
The Compensator regulates the hydraulic pressure and is preset at the factory. It is set to signal the pump to provide and
maintain Stand-By Pressure (500 psi). Also, it limits the working pressure to 2500 psi. It also acts as a variable flow switch
for the pump. The more pressure we provide to the load sense line from the valve, the more flow the pump provides the
valve and cylinders we are using.
Please call Heil Technical Services at 866-310-4345 BEFORE attempting any adjustments. It is rare for this to be out of
adjustment.
