Voltmaster Trash Pumps
3 Operation
3.1 Before starting
3.1.1 Safety
Before operating the Voltmaster Trash Pump:
■
Read and be familiar with this instruction manual.
■
Read and follow all safety instructions (see Section 2.1, page 3).
■
Read and follow instructions in the engine manufacturer’s documentation.
3.1.2 Flow considerations
■
Ensure the power unit, pump, wiring, and piping installations are suitable for the fluid being
pumped and comply with all applicable codes and ordinances.
■
DO NOT expose pump to extremes conditions of acidity or basicity. If necessary, consult factory
for specific recommendations regarding chemicals and temperatures.
■
Drain the pump whenever there is a danger of freezing.
■
Overheating can occur if either the suction or discharge becomes restricted. If flow becomes
restricted, refer to Section 4,
Troubleshooting , page 9.
■
Before operating, ensure pump is on a firm, flat, level surface.
■
If pump is located next to a pit or hole, ensure pump is anchored so that it cannot fall in.
■
Locate pump as close to the level of the fluid to be pumped, but never higher than 25 feet (7.5m)
above fluid surface.
■
Keep hoses and piping straight and as short as possible, avoiding sharp bends.
■
If hoses must be laid across a roadway, protect it with planking. Instantaneous shutoff pressure,
applied when a vehicle runs over an unprotected hose, will cause “hydraulic shock” and may
damage the pump.
■
If the discharge line runs vertically more than 30 feet (9m), it is advisable to install a check valve in
the discharge line, near the pump, to stop destructive liquid hammer when the pump is shut
down.
❑
If a check valve is installed, it may be necessary to vent the top of the pump so that air can be
expelled during automatic priming. This can be accomplished by providing a 1/4-inch
(0.5cm) line from the top of the pump back to the fluid source.
❑
If a check valve is not installed, the manufacturer cannot assume responsibility for damage
to the pump due to destructive liquid hammer.
CAUTION
An overheated pump can be extremely hot, resulting
in severe burns.
Stop pump immediately if overheating occurs. Then,
slowly and with great caution, vent pump at drain plug.
