7. The discharge side may utilize proper discharge hoses,
PVC pipe, or concrete pipe.
8. Check that discharge hoses lay flat and as straight as
possible. Remove any sharp bends or kinks from the
hose so the water flow cannot be blocked.
9. Once the engine is started; and depending on the
application set-up, the priming process will take a few
moments before water begins to flow.
10. The performance of the pump (Flow, Head, Water
Velocity, and Pressure) is dependent on the many
factors that surround the application. These factors
include, but are not limited to: operating altitude, suction
lift, discharge and suction hose diameter and length,
overall friction loss coefficients, the specify gravity of
the fluid to be pumped, the fluid temperature, and total
discharge head.
CAUTION
The strainer should be positioned so it will remain
completely
under water
. Running the pump with the
strainer above water for long periods can damage the
pump.
1. It is advantageous to place the pump as close as
possible to the water source (Figure 7) on a solid,
level operating surface. The most critical factor for
successful pump operations is not to exceed 25’ Total
Suction Lift (at sea level).
2. Ensure that the pump has the proper level of fuel and
engine oil.
3. Initially prime the pump by removing the fill cap (see
Figure 3) and filling the casing with water. If the pump
casing is not filled with water prior to operations, it will
not be able to start the pumping process and you risk
overheating the mechanical seal assembly.
4. Attach the proper suction and discharge hoses to the
pump ports. Ensure that the hose O-rings are in place,
and that hose do not show any cracks, gouges, or
holes. The hoses should not be kinked, and must be
secured tightly to their respective ports.
5. A proper suction hose is commonly reinforced with rigid
PVC helix and is specifically designed to safeguard
against collapsing during pumping operations. It is
essential that the pump utilize a suction hose with the
same diameter as the suction port.
6. Ensure that the strainer is placed on the end of the
suction hose, and that the hose is placed in the water
source in such a manner as not to bury the strainer
into sand or silt.
