APPLICATION
QP4TZ Trash Pump
The
is designed to be used for dewatering
applications. Both the suction and discharge ports on the QP4TZ
trash pump use a 4-inch diameter opening, which allows the
pump to pump at a rate of approximately 526 gallons/minute
(gpm) or 2,000 liters/minute (lpm).
Trash or self-priming pumps are designed to purge air from the
suction line and create a partial vacuum in the pump body. The
reduced atmospheric pressure inside the pump allows water to
flow through the suction line and into the pump body. The
centrifugal force created by the rotating impeller pressurizes the
Elevation
Higher elevations will effect the performance of the pump. Due to
less atmospheric pressure at higher altitudes, pumps DO NOT
have the priming ability that they have at sea level. This is due to
the “thinner air” or lack of oxygen at higher altitudes.
A general rule of thumb is that for every 1,000 feet of elevation
above sea level a pump will lose one foot of priming ability.
For example, in Flagstaff, Arizona where the elevation is
approximately 7,000 feet, the pump would have a suction lift of
25 feet rather than the 18 feet at sea level. Table 3 shows suction
lift at various elevations.

HATZ 1B40
Trash Pump
Trash pumps derive their name from their ability to handle a
greater amount of debris and solids than standard centrifugal
pumps. This pump generally handle solids up to 1/2 the size of
the discharge opening making them less likely to clog. Also trash

pumps are capable of handling water with 25% solids by weight.
This pump is intended to be used for dewatering applications
and is capable of suction lifts up to 25 feet at sea level. For
optimal suction lift performance, keep the suction hose or line as
short as possible. In general, always place the pump as close to
the water as possible.

PUMP COMPONENTS
Figure 2 shows a typical application using the QP4TZ 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 1.5 inch (30 mm) in diameter. DONOT 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- 4TZ Pump Application
1.Pump – The model QP4TZ is a 4-inch trash pump used in
general dewatering 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
either port (one of two ports).
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.

To perform the pump vacuum test do the following:
1.Remove the pump fill cap (Figure 2), and fill the pump with
water.
2.Start the engine as outlined in the initial start-up section,
and wait for the pump to begin pumping.
3.As shown in Figure 13, place a water hose inside the
discharge opening of the pump, and turn on the water. This
flow of water into the discharge opening will
pump from running dry.

pump suction (inlet) opening (Figure 13) with the vacuum
gauge facing upwards. It may be necessary to apply a small
amount of water around the rubber seal of the vacuum tester
to make a good suction fit.

6.To test the
tester should remain attached to the pump suction inlet port
by vacuum. This indicates the pump's flapper valve is seating
properly to hold water in the suction hose when the engine
is stopped. This prevents backflow and allows for faster
priming when the engine is restarted.

Pump Cleaning
After pumping water containing large amounts of dirt and debris,
perform the following:
1.Remove the drain plug from the pump housing (Figure 2)
and drain any water left in the pump.
2.Loosen the two locking hand knobs (turn counterclockwise)
and remove
3.Clean and remove dirt, debris from pump casing. Inspect
impeller and volute for wear. Replace any damaged or worn

PREPARATION FOR LONG -TERM STORAGE
Pump Storage
For storage of the pump for over 30 days, the following is
required:
z
Drain the fuel tank completely.
z
Run the engine for about 3 minutes and then stop.
z
Stop the engine. Drain the engine crankcase oil while
the engine is still warm. Fill engine crankcase with fresh
oil.
z
Pull the recoil starter grip (Figure 17) 2 or 3 times. DO
NOT start the engine.
z
Pull the recoil starter grip slowly. STOP when it feels
tight. This closes the intake and exhaust valves
(compression position), and helps prevents rust from
forming.
z
Wipe any oil or dirt that may have accumulated on the
engine.
z
Remove the drain plug from the pump and drain out any
water left in the housing.
z
Remove the pump cover and clean the inside of pump
housing. Coat the inside of pump housing with a light
film of oil to reduce corrosion. A spray can of oil works
well for this application.
z
Cover suction and discharge ports with duct tape to
prevent any foreign matter from falling into pump.
z
Cover pump and engine with plastic covering or
equivalent and store in a clean, dry place.
z
To protect the water-cooled seals, place one-half pint of
lubricating oil (new or used) through the discharge opening
on the pump and crank the engine several times. This
will prevent excessive corrosion and also keep the
mechanical seal lubricated.
