Pumping from the On-Board Tank

Follow the instructions to operate the pump from the on-board tank.

 High Pressure Hazard:

 Prior to connection of hoses, caps or other 

closures with pump intake or pump discharge connections, relieve 

pressure by opening drains.

 Scalding Water Hazard:

 When operating the pump, be sure to open at 

least one discharge valve slightly to prevent the pump from overheating. 

If the pump runs for a few minutes completely closed, it may heat the 

water enough to scald someone when the valve is opened. Overheating 

can damage the packing, seals and other pump parts. If the apparatus 

builder has installed a by-pass system or other provision designed to 

prevent overheating, opening a discharge valve may be unnecessary.

 Unexpected Truck Movement:

 Failure to properly shift transmission in 

accordance with the transmission operating instructions may result in 

unexpected truck movement which may result in serious personal injury 

or death.

1.  Engage the pump—refer to the pump transmission instructions for your 

application.

2.  Switch transfer valve to desired position.

NOTE:

 As a general rule, keep the transfer valve in pressure position when 

pumping up to 2/3 of the rated capacity of the pump and in volume 

when pumping more than 2/3 of the rated capacity. If high pressure 

is required (more than 200 psi, 13.8 bar), operating the pump in the 

PRESSURE position may be necessary even if it means closing one 

or more valves to reduce volume and avoid cavitation. The transfer 

valve may be changed from one position to the other while operating 

the pump. Decreasing the discharge pressure will make this easier. If 

the pump has a manually operated transfer valve, slow engine speed 

to reduce the discharge pressure to 75 psi (5.2 bar) or less. With the 

electric transfer valve, reducing the discharge pressure is necessary 

only if it exceeds 250 psi (17.3 bar).

3.  Open valve(s) in piping between water tank.
4. 

Allow about 30 seconds for water to flow into pump.

NOTE:

 Priming the pump may be necessary because of air trapped in 

piping.

5.  Accelerate engine to obtain desired discharge pressure and capacity.
6.  Set relief valves or other pressure governing device to desired pressure.

After operation do the following:

 High Pressure Hazard:

 Prior to removal of hoses, caps or other 

closures with pump intake or pump discharge connections, relieve 

pressure by opening the drains.

1.  Disengage the pump—refer to the pump transmission instructions for your 

application.

2. 

If pumping other than clean water during operation, flush the pump until all 

contaminants are removed.

3.  Close all drains and install intake and discharge caps.
