11 EATON 420 Mobile Piston Pump Technical Manual E-PUPI-TM002-E4 November 2014

Control Options

Remote Pressure Control

Remote relief valve is to be

connected to pilot port “J”

through necessary external

piping. Standard differential

pressure of 20 bar is set

at RPC spool. The required

outlet pressure (below 280

bar) can be set by adjusting

remote relief valve setting.

Once pressure reaches pre-

set value, ow across remote

relief valve starts, this results

in RPC spool movement due

to pressure imbalance. This

will de-stroke the pump to

maintain the set pressure.

Secondary pressure compen-

sator is provided to limit the

max pressure setting as a fail

safe measure. The delta pres-

sure is factory set which can

not be changed.

Delta Pressure setting at control valve - bar (psi) 14 - 24 (200 - 350)

Control uid consumption - lpm (gpm) 4.5 (1.2) max.

Recommended ow rating of remote relief valve- lpm (gpm) 3 – 5 (0.8 – 1.32)

Recommended Eaton Relief Valve part number RV5-10-S-0-50

* Flow Compensator is not

available with RPC.

* Flow Compensator/

Remote Pressure Control

setting should be selected

(140-350 psi).

* Remote relief valve is not

included in supply scope of

the pump.
