PUMP COMPONENTS

Figure 2 shows a typical application using the QP4TE Centrifugal Trash pump. Please note that this pump is intended for the removal of clean water and water containing some debris and solids. Maximum size of solids should not exceed 2 inches (50 mm) in diameter. DO NOT set strainer on bottom of water bed. Placing the strainer above the water bed will prevent the pump from drawing in excessive amounts of sand and foreign debris.

Figure 2. QP4TE Pump Application

1.	Pump – The MQ Model QP4TE is a 4-inch trash pump
	used in general de-watering applications. Typical
	dewatering applications consist of manholes, septic tanks,
	fast and slow seepage ditch water, silt water, mud water
	and muck water.
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.	Clean-out Cover Handles –To gain access to the pump's
	clean-out area, grip both handles, then pull to remove cover.
	Make sure both locking knobs have been released before
	attempting to remove clean-out cover.
9.	Drain Plug – Remove this plug to drain water from the
	pump.

10. Clean-out Cover – Remove cover to gain access to the clean-out area.

11. Locking Knobs – Turn both knobs clockwise to secure clean-out cover, turn counter-clockwise to release cover.

12. 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.
