All hoses/piping should be supported, braced and lined up square before connection to the pump flanges.
A flexible fitting is recommended on both suction and discharge to eliminate misalignment loads or stresses
being transmitted to the pump.
Note:
Flexible pipe couplings must be restrained so as not to transmit any strain to the pump flanges when expanding
or contracting under pressure. Unrestrained expansion fittings can transmit enormous forces to the pump flanges.
WARNING
The pump is designed to handle water and/or other liquids containing some slurries
and other entrained solids up to a certain diameter (refer to
for the correct diameter). It MUST NOT be used to pump volatile, corrosive
or flammable materials that can damage the pump, cause pump failure, or result in
explosion. Serious personal injury could result.
PUMP SET UP
1.
Disconnect the pump from the tow vehicle by turning the tongue jack
clockwise to raise the tongue from the hitch. Disconnect all safety chains,
surge brake cables and the trailer wiring harness. Chock the wheels to
prevent the unit from rolling.
2.
Lower the rear leveling jacks from the travel position. Turn the jack
handles clockwise until the leveling feet are in firm contact with the
ground. Adjust the jacks until the pump is as level as possible.
3.
Attach fittings to both the intake and outlet openings of the pump, making
sure they match the fittings on the hoses. Make sure a gasket/seal is in
place between the pump volute and the flange on the fitting being
attached. Tighten all hardware completely to ensure an airtight seal.
Threaded fittings require the use of pipe thread sealant.
4.
Attach a rigid hose to the intake (suction) side of the pump. To prevent cavitation, the suction hose/piping should
be at least as large as the pump flange, never smaller. The pump should be at the highest point of the hose/
piping. All suction piping and fittings should be checked for any foreign material (rocks, bolts, wire, etc.) and also
any sharp burrs that could disrupt the flow. Make sure the O-ring seal is present in the fitting on the pump before
attaching the fitting.
Note:
Lubricate the O-ring seal with grease to ensure an airtight seal.
CAUTION
The suction and discharge pipe/hose material should be compatible with the liquid being
pumped. If a hose is used on the suction line, it should be of the reinforced type to prevent
collapse under suction lift.
DANGER
IF A MANUAL SHUTOFF VALVE IS INSTALLED IN THE DISCHARGE LINE, IT MUST
NOT BE LEFT CLOSED DURING OPERATION. A CLOSED MANUAL SHUTOFF VALVE
WILL CAUSE OVERHEATING AND POSSIBLE EXPLOSIVE RUPTURE OF THE PUMP
CASING. PERSONNEL COULD BE SERIOUSLY INJURED.
5.
Attach a rigid intake screen or strainer to the end of the suction hose before placing it in the liquid. This will
prevent large items or excessive trash from entering the pump housing. The screen must have enough openings
to equal four times the area of the intake hose (6” x 3.14 = 18.84 sq in x 4 = 75.36 sq in [486 sq cm]). The screen
should be rigid enough to prevent collapse when flow is reduced due to clogging.
6.
Place the intake hose into the liquid to be pumped. The submergence of the suction pipe into the liquid should
be at least four to five times the pipe diameter. If this is not possible, provide a baffle or a floating board. This is
to prevent any vortex action allowing air into the pipe/hose. For best performance, a bell mouth fitting is
