Figure 2 shows a typical application using the QP-402H centrifugal pump. Please note that this pump is intended for the removal of clean water.

Figure 2. QP-402H Pump Application

8 4 6

1.	Pump – The model QP-402H is a 4-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 4-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 4-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.
