Operation (Hydraulic-Powered Pumps)
Starting and Adjusting the Pump
1.Charge the surge tank, if you are using one. See the separate instruction manual,
2.Open all shutoff valves (D).
3.Turn on the hydraulic power supply.
4.Open the flow control valve (S) all the way.
5.Open the return line shutoff valve first, then open the supply line shutoff valve.
6.Open the dispensing valve/spray gun at the last gun station and keep it open while starting the pump.
7.Adjust the pressure reducing valve (P) until you get the desired fluid pressure.
8.When fluid is flowing smoothly from the gun, release the gun trigger.
9.One at a time, open any other guns in the system to purge air from the lines.
10.With a gun triggered open
11.Open the flow control valve (S) slowly until the cycle rate and fluid pressure return to the desired level. This method of setting the hydraulic controls ensures proper pump operation and prevents pump runaway and damage if the fluid supply runs dry.
12. Release the gun trigger.
NOTE: In a circulating system, the pump operates continuously until the power supply is shut off. In a direct supply system, the pump starts when the gun/ valve is opened, and stops when the gun/valve is closed. The pump always stops on the downstroke due to the vented inlet seat (32).
WARNING
COMPONENT RUPTURE HAZARD To reduce the risk of overpressurizing your system, which could cause component rupture and serious injury,
never exceed the specified maximum hydraulic input pressure to the pump (see Technical Data on page 46).
Shutdown
WARNING
To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 12.
Relieve the pressure.
Always shut off the supply line shutoff valve first, and then the return line shutoff valve. This is to prevent overpressurizing the motor or its seals.
