MQ-D2H/D3H DIAPHRAGM PUMPS -- OPERATION AND PARTS MANUAL-- REV. #3 (04/02/08) -- PAGE 11
MQ-D2H/D3H -- GENERAL INFORMATION
APPLICATION
The MQ-D2H and MQ-D3H diaphragm pumps are designed to be used for de-watering applications.The suction and discharge ports on the MQ-D2H use a 2-inch diameter opening, which allows the pump to pump at rate of approximately 3,000 gallons/ hour (gph) or 11,340 liters/hour (lph). The suction and discharge ports on the MQ-D3H use a 3-inch diameter opening, which allows the pump to pump at rate of approximately 5,400 gallons/ hour (gph) or 20,456 liters/hour (lph).
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.
Power Plant
These diaphragm pumps are powered by a 4.0 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.
Oil Alert Feature
In the event of low oil or no oil, the HONDA GX-120 engine has a built-in oil alarm engine shut-down feature. In the event the oil level is low the engine will automatically shut-down.
Suction Lift
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 Support
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.
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 only 18 feet rather than the 25 feet at sea level. Table 3 shows suction lift at various elevations.

2. Use only premium lithium based grease, conforming to NLG1 Grade #2 consistency.
NOTE
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.
Gear Reduction Oil (Transmission)
1. Remove the transmission oil level plug (Figure 7). If oil begins to seep out as the plug is being removed, then it can be assumed that the transmission oil is at the proper operating level.
2. If oil does not seep out as the oil level plug is being removed, then remove the transmission oil fill plug and fill with SAE 80/90 EP (API GL-5) gear oil to the proper operating level. Transmission oil capacity is capacity is 22 ounces (651 ml.).
Figure 8. Connecting Rod Bearing Lubrication
Helpful Hints The capacity of this diaphragm pump will vary greatly depending on the height of the suction lift and length of the discharge hose. A discharge hose which is too small, long or high will cause the following: Excessive bulging of diaphragm on the down stroke. Valves closing with a loud snap. Rough operation. Engine overloads and slow downs. Reduced efficiency.

MQ-D2H/D3H -- MAINTENANCE (PUMP)
Pump Vacuum Test
To perform the pump vacuum test do the following:
1. Start the engine as outlined in the initial start-up section, and wait for the pump to begin pumping.
2 Check and make sure that there are no air leaks between the vacuum tester (Figure 21) and the inlet port on the pump. If air leaks are present reseat vacuum tester.
3. 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.
Flapper Valve Replacement
1. Remove the two bolts that secure the suction port chamber (Figure 20) to the pump well. Remove suction port chamber. Replace valves as required and reassemble.
NOTE
22 in. Hg (inches of mercury) translates into 25 feet of lift at sea level.
4. If the vacuum tester gauge indicates a reading
below -20 in. Hg, it can then be assumed that the pump
Figure 20. Flapper Valve Replacement
is not functioning correctly, and corrective action needs
to be taken.
2. Remove the two bolts that secure the discharge port
5. To test the flapper valve, shut down the engine. The
(Figure 20) to the pump well. Remove discharge port plate.Replace valves as required and reassemble.
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.
Gear Reduction Oil (Transmission)
1. Check gearbox oil level every 20 hours of operation or at least once a week; more often if any leakage is detected around the gearbox.
2. Change transmission oil after the first 40 hours of
operation. Use SAE 80/90 EP (API GL-5) gear oil.
Transmission oil capacity is 22 ounces (651 ml.). Check
oil level periodically and change oil after every 350 hours
of operation.
Connecting Rod Bearing Lubrication
1. Grease connecting rod bearing (Figure 8) every 8 hours of operation.This is done by rotating the rod bearing to the 12 o'clock position. At this point the grease fitting will be visible through the guard hole.
2. Use only premium lithium based grease, conforming to NLG1 Grade #2 consistency.
3. Remove connecting rod guard occasionally and wipe up excess grease from connecting rod bearing.

Rotation of Suction and Discharge Ports
In some applications, it may be preferable to have suction/ discharge ports rotated 90° (Figure 22) to be in-line with the pump wheels. Perform the following procedure to rotate ports:
1. Remove the four hex head cap screws, hex nuts, flat washers and lock washers from the pump base.
2. Push pump well downwards to separate from pump base.
3. Rotate pump well 90° clockwise so that driver is positioned over top of discharge plate.
4. Align pump well, pump base, and diaphragm with each other. Once all components have been properly aligned, reinstall the four hex head cap screws, hex nuts, flat and lock washers and tighten securely.
CAUTION - Stalled or Stopped Pump
If pump has stopped or stalled for any unknown reason, clean out pump cavity (well) thoroughly. Failure to comply could result in damage to plunger arm or other internal pump components.
Stalled Pump
If pump has stalled for any unknown reason perform the following: 1. Remove handle from pump. See Figure 6. 2. Remove the four hex head cap screws, hex nuts, flat
washers and lock washers from the pump base. 3. Push pump well downwards (Figure 23) to separate from
pump base. 4. Clean and remove all dirt and debris from pump well. 5. Align pump well, pump base, and diaphragm with each
other. Once all components have been properly aligned, reinstall the four hex head cap screws, hex nuts, flat and lock washers and tighten securely.
Figure 22. Suction/Discharge Port Rotation
Clearing a Jam-Up
If large solids or an accumulation of sand or other sediment becomes lodged in the pump well preventing the plunger arm from making a full stroke, the pump will either stall or the crank will slip on the output shaft.The MQ-D2H/D3H diaphragm pumps are designed to react this way to prevent severe internal damage.
If a jam-up does occur, the pump should be thoroughly cleaned as describe on the "Pump Stalls" section.
Figure 23. Pump Well (Clean-out)
WARNING - Lock Screw Torqueing
Pump jamming with an over-torqued lock screw (plunger arm) may cause internal damage. Under torqueing may allow the output shaft to spin and wear parts prematurely causing replacement.
