MQ-D306HA — GENERAL INFORMATION
Elevation
APPLICATION
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.
The MQ Model D305HA diaphragm pump is designed to be
used for de-watering applications. The suction and discharge
ports on this pump use a 3-inch diameter opening, which allows
the pump to pump at rate of approximately 5,100 gallons/hour
(gph) or 19,305 liters/hour (lph).
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.
Diaphragm pumps use a positive displacement design rather
than centrifugal force to move water through the casing. This
means the pump will deliver a specific amount of flow per stroke,
revolution or cycle. These pumps are commonly referred to as
mud hogs, mud hens and mud suckers.Their names reflect their
popularity for use in applications where shallow depths and slurry
water render centrifugal pumps ineffective
For example, in Flagstaff, Arizona where the elevation is
approximately 7,000 feet, the pump would have a suction lift of
only 18 feet rather than the 25 feet at sea level. Table 3 shows
suction lift at various elevations.

This diaphragm pump is powered by a 5.5 horsepower air cooled,
4-stroke, single cylinder, HONDA GX-120 gasoline engine that
incorporates a low "Oil Alert Feature" . The drive shaft of the
engine is coupled to an offset connecting rod that is coupled to a
flexible diaphragm. The connecting rod alternately raises
(expands) and lowers (contracts) the diaphragm at a rate
between 40 and 65 strokes per minute depending on engine
speed.

The pump should always be placed on solid stationary ground
in a level position.
NEVER place the pump on soft soil. The suction hose or pipe
connection should always be checked for tightness and leaks. A
small suction leak in the hose or fittings could prevent the pump
from priming.
Please contact your nearest authorized MQ
dealer for any accessories that your pump
may require.

MQ-D306HA — PUMP COMPONENTS
Figure 2 shows a typical application using the MQ D306HA series diaphragm 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 (38 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.
Contact your nearest
Multiquip dealer for
quick disconnect hoses
and fittings.
Figure 2. MQ-D306HA Pump Application
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.

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.
8. 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.
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.
9. Support Body – This unit is equipped with a hinged
support assembly, that allows for easy access to the pump
body.
3. Discharge Port – Connect a 3-inch discharge hose to
this port. Use two worm clamps to secure the hose.

4. Check that the discharge hose (Figure 2) is not restricted.
Place hose so that it lays as straight as it is possible on the
ground. Remove any twists or sharp bends from hose which
may block the flow of water.
NEVER operate the pump in a confined
area or enclosed area structure that does
not provide ample free flow of air.
ALWAYS wear approved eye and hearing
protection before operating the
compactor.
Suction and discharge hoses are
NOTE
available from Multiquip. Contact
your nearest dealer for more
information.
Before Starting
5. The discharge hose is usually a collapsible (thin-walled)
hose, however if a thin-walled discharge hose is not avail-
able, a rigid suction hose can be substituted in its place.
1. Read safety instructions at the
beginning of manual.
2. Place pump as near to water as
possible,onafirmflat,levelsurface.
6. Make sure the suction strainer (Figure 2) is clean and
securely attached to the water end of the suction hose. The
strainer is designed to protect the pump by preventing large
objects from being pulled into the pump.
3. Toprimepump,removefillcap(Figure2)andfillpumpcasing
with water.If the pump casing is not filled with water before
starting, it will not begin pumping.
CAUTION - Strainer
The strainer should be positioned so it will remain completely
under water. Running the pump with the strainer above
water for long periods can damage the pump.
CAUTION - Pump Casing
Pump casing must be filled with water before using
pump. Otherwise pump will not be able to begin
pumping.
CAUTION - Flammable Fluids
DO NOT pump flammable fluids, corrosive chemicals or fluids
containing toxic substances. These fluids can create potentially
dangerous health and environmental hazards. Contact local
authorities for assistance.
WARNING - Fill Cap
DO NOT open fill cap if pump is hot! Water inside may
be under pressure.
4. Checkforleaksbetweenpumpandengine.Ifwaterisleaking
between the pump and engine housing, the seal inside the
pumpmaybewornordamaged.Continued operationofthe
pumpisnot recommended.Furtherusageofthe pumpunder
theseconditionsmaycauseseverewaterdamagetoengine.
CAUTION - Mechanical Seal
This pump uses a water-cooled mechanical seal to prevent
water from seeping into the engine. The passage of water
through the pump casing lubricates the seal and prevents it
from overheating. NEVER! operate the pump without water
in the casing as this will cause damage to the mechanical
seal.
Hoses and Clamps
1. Check that all hoses are securely attached to the pump.
Make certain suction hose (Figure 2) does not have any air
leakage.Tighten hose clamps and couplings as required.
2. Itisrecommendedthat 2 clampsbeusedwhensecuringthe
suction hose to the inlet side (suction) of the pump.

MQ-D306HA — MAINTENANCE (PUMP)
Pump Vacuum Test
CAUTION - Priming Pump
Pump Cleaning
After pumping water containing large amounts of dirt and
debris, perform the following:
DO NOT attempt to start the engine unless the pump has
previously been primed with water. Severe pump damage
will occur if pump has not been primed.
1. Remove the drain plug from the pump housing (Figure 2)
and drain any water left in the pump.
3. Clean and remove dirt, debris from pump casing.Inspect
impeller and volute for wear. Replace any damaged or
worn parts.
To perform the pump vacuum test do the following:
Gear Reduction Oil (Transmission)
1. Remove the pump fill cap (Figure 2), and fill the pump
with water.
1.
Change transmission oil after the first 40 hours of
operation. Use SAE 80/90 EP gear oil. Transmission oil
capacity is 1-1/4 pints (590 ml.). Check oil level periodically
and change oil after every 400 hours of operation.
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 19 (next page), 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 prevent the pump from running dry.
Connecting Rod Bearing Lubrication
1. Grease connecting rod bearing thru the access
hole (Figure 7) every 25 hours of operation.
2.
Use only premium lithium based grease, conforming to
NLG1 Grade #2 consistency.
4. Place the Pump Vacuum Tester (P/N 7000030) over
the pump suction (inlet) opening (Figure 19) 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.
Connecting Rod Bearing Lubrication
1. Keep interior of pump and valves clean. Flush out
pump with clear water after operation.
2. Remove connecting rod guard occasionally and wipe
up excess grease from connecting rod bearing.
5. Check and make sure that there are no air leaks between
the vacuum tester and the inlet port on the pump. If air
leaks are present reseat vacuum tester.
6. Run the pump for a few minutes while monitoring the
vacuum gauge. If the gauge indicates a reading between
-25 and -20 in. Hg. (inches of mercury) then it can be
assumed that the pump is working correctly.
25 in. Hg (inches of mercury)
translates into 25 feet of lift at sea
level.
7. If the vacuum tester gauge indicates a reading
below -20 in. Hg, it can then be assumed that the pump
is not functioning correctly, and corrective action needs
to be taken.
6. To test the flapper valve, shut down the engine. The
vacuum 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.
