Operation
Proportioning Pump Chart
Displacement pump combinations for mix ratio, pres-
sure ratio and volume per cycle for each model.
CAUTION
With three displacement pump models, the outer two
displacement pumps must be identical models to
balance forces and avoid damaging the pumps.

Relief Valve Selection Table
To select the appropriate relief valve:
1.
Determine the Maximum Pump Fluid Pressure of
your system.
2.
Verify that all system components meet or exceed
the pressure ratings of the pressure relief valve
that you have selected.
3.
Select the lowest pressure relief valve with a maxi-
mum working pressure that exceeds the Maximum
Pump Fluid Pressure.
