PRESSURE ADJUSTMENT
IMPORTANT
DANgER !
Before starting pump, be sure all drive
equipment guards are in place.
failure to properly mount guards may
result in serious injury or death.
ASSEMBLY
Reverse the procedures outlined under
“Disassembly,”
page 10. If the valve is removed for repairs, be sure to
replace in the same position. The relief valve adjusting screw
cap must always point towards the suction side of the pump.
If pump rotation is reversed, remove the relief valve and turn
end for end.
If a new spring is installed or if pressure setting of the
pressure relief valve is to be changed from that which the
factory has set, the following instructions must be carefully
followed.
1. Carefully remove the valve cap that covers the adjusting
screw.
2. Loosen the locknut that locks the adjusting screw so
the pressure setting will not change during operation of
the pump.
3. Install a pressure gauge in the discharge line for the
actual adjusting operation.
4. Turn
the adjusting screw in to increase the pressure and
out to decrease the pressure.
5. To test the valve setting, slowly close the line valve on
the downstream side of the pump until the pressure
relief valve opens and flow through the pump stops. This
will show the maximum discharge pressure the valve
allows at the current setting. Limit the amount of time
in this condition to prevent overheating of the pump due
to internal recirculation of the liquid.
In ordering parts for the pressure relief valve, always
give the model number and serial number of the pump
as it appears on the nameplate and the name of the part
wanted. When ordering springs, be sure to give the pressure
setting desired.
