MQ62TK SERIES TRASH PUMP • OPERATION AND PARTS MANUAL — REV. #0 (01/30/18) — PAGE 27
SETUP
The MQ62TK series trash pump is intended for the removal
of clean water or water containing some debris and solids.
Maximum size of solids should not exceed 3 inches (76 mm)
in diameter. Figure 11 below shows a typical trash pump
application.
1. It is advantageous to place the pump as close as
possible to the water source on a solid, level operating
surface. The most critical factor for successful pump
operation is to not exceed 25 feet (7.62 meters)total
suction lift (at sea level).
2. Ensure that the pump has the proper level of engine oil.
3. Initially prime the pump by removing the fill cap and
filling the casing with water. If the pump casing is not
filled with water prior to operation, 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 all hose O-rings are in place,
and that the hoses 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 to not bury the strainer in
the sand or silt.
7. The discharge side may utilize proper discharge hoses,
PVC pipe, or concrete pipe.
8. Check that the discharge hose lays 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 setup, 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 specific gravity of
the fluid to be pumped, the fluid temperature, and the
total discharge head.
CAUTION
The strainer should be positioned so it will remain
completely underwater. Running the pump with the
strainer above water for long periods can damage the
pump.
