QP-204H CENTRIFUGAL PUMP — OPERATION AND PARTS MANUAL— REV. #3 (06/05/06) — PAGE 13
Figure 2 shows a typical application using the QP-204H centrifugal pump. Please note that this pump is intended for the removal of
clean water.
1. Pump – The model QP-204H is 2-inch centrifugal pump
used in general de-watering applications. Typical
dewatering applications consist of dewatering basements
and swimming pools.
2. Fill Cap – Prior to operation, the pump casing should be
filled with water. Remove this cap to add water to the pump.
After the initial prime, a sufficient amount of water will be
retained in the casing so that the operator will not need to
re-prime later.
If the casing is dry or has insufficient water, the pump will
have difficulty in priming which could lead to premature
mechanical seal wear thus causing damage to the pump.
3. Discharge Port – Connect a 2-inch discharge hose to this
port.
4. Worm Clamp – Used to secure the hose to the inlet and
outlet ports on the pump. Use two clamps to secure the
hose on the inlet side of the pump.
5. Discharge Hose – Connect this flexible rubber hose to
the discharge port on the pump. Make sure that the hose
lays flat and is not kinked. Use only recommended type
discharge hose. Contact Multiquip parts department for
ordering information.
6. Suction Port – Connect a 2-inch inlet hose to this port.
Use two worm clamps to secure the hose.
7. Suction Hose – Connect this flexible rubber hose to the
suction port on the pump. Make sure that the hose lays flat
and is not kinked. Use only recommended type suction
hose. Contact Multiquip parts department for ordering
information.
8. Drain Plug – Remove this plug to drain water from the
pump.
9. Strainer – Always attach a strainer to bottom side of the
suction hose to prevent large objects and debris from
entering the pump. Strainer should be positioned so that it
will remain completely under water. Running the pump with
the strainer above water for long periods can damage pump.
