QP40TH — PUMP COMPONENTS

Figure 2 shows a typical application using the QP40TH 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. QP-40TH Pump Application

1.

Pump – The model MQ40TDH is 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.
