PAGE 12 — QP-204H CENTRIFUGAL PUMP — OPERATION AND PARTS MANUAL — REV. #3 (06/05/06)
QP-204H — GENERAL INFORMATION
APPLICATIONThe QP204H Centrifugal Pump is designed to handle all typesof clear water applications. It is ideal for residential use such asdewatering basements and swimming pools. Both the suctionand discharge ports on the QP-204H pump use a 2-inch diameteropening, which allows the pump to pump at a rate ofapproximately 142 gallons/minute (gpm) or 538 liters/minute(lpm).
Centrifugal or self priming pumps are designed to purge air fromthe suction line and create a partial vacuum in the pump body.The reduced atmospheric pressure inside the pump allows waterto flow through the suction line and into the pump body. Thecentrifugal force created by the rotating impeller pressurizes thewater and expels it from the pump.
Power Plant
This centrifugal pump is powered by an 4.0 horsepower air cooled4-stroke, single cylinder HONDA GX-120 gasoline engine thatincorporates a low "Oil Alert Feature"
Oil Alert FeatureIn the event of low oil or no oil, the HONDA GX-120 engine hasa built-in oil alarm engine shut-down feature. In the event the oillevel is low the engine will automatically shut-down.
Standard Centrifugal PumpStandard centrifugal pumps provide an economical choice forgeneral purpose dewatering. These types of pumps should onlybe used in clear water applications (agricultural, industrial,residential) as they have a limited solid handling capability ofonly 10% by volume.
Suction LiftThis pump is intended to be used for dewatering applicationsand is capable of suction lifts up to 25 feet at sea level. Foroptimal suction lift performance keep the suction hose or line asshort as possible. In general, always place the pump as close tothe water as possible.
Pump SupportThe pump should always be placed on solid stationaryground, on a level position.
NEVER place the pump on soft soil. The suction hose or pipeconnection should always be checked for tightness and leaks. Asmall suction leak in the hose or fittings could prevent the pumpfrom priming.
ElevationHigher elevations will effect the performance of the pump. Due toless atmospheric pressure at higher altitudes, pumps DO NOThave the priming ability that they have at sea level. This is due tothe “thinner air” or lack of oxygen at higher altitudes.
A general rule of thumb is that for every 1,000 feet of elevationabove sea level a pump will lose one foot of priming ability.
For example, in Flagstaff, Arizona where the elevation isapproximately 7,000 feet, the pump would have a suction lift ofonly 18 feet rather than the 25 feet at sea level. Table 3 showssuction lift at various elevations.
Table 4 shows percentage drops in performance as elevationincreases.
QP-204H CENTRIFUGAL PUMP — OPERATION AND PARTS MANUAL— REV. #3 (06/05/06) — PAGE 13
Figure 2 shows a typical application using the QP-204H centrifugal pump. Please note that this pump is intended for the removal ofclean water.
1. Pump – The model QP-204H is 2-inch centrifugal pumpused in general de-watering applications. Typicaldewatering applications consist of dewatering basementsand swimming pools.
2. Fill Cap – Prior to operation, the pump casing should befilled with water. Remove this cap to add water to the pump.After the initial prime, a sufficient amount of water will beretained in the casing so that the operator will not need tore-prime later.
If the casing is dry or has insufficient water, the pump willhave difficulty in priming which could lead to prematuremechanical seal wear thus causing damage to the pump.
3. Discharge Port – Connect a 2-inch discharge hose to thisport.
4. Worm Clamp – Used to secure the hose to the inlet andoutlet ports on the pump. Use two clamps to secure thehose on the inlet side of the pump.
5. Discharge Hose – Connect this flexible rubber hose tothe discharge port on the pump. Make sure that the hoselays flat and is not kinked. Use only recommended typedischarge hose. Contact Multiquip parts department forordering information.
6. Suction Port – Connect a 2-inch inlet hose to this port.Use two worm clamps to secure the hose.
7. Suction Hose – Connect this flexible rubber hose to thesuction port on the pump. Make sure that the hose lays flatand is not kinked. Use only recommended type suctionhose. Contact Multiquip parts department for orderinginformation.
8. Drain Plug – Remove this plug to drain water from thepump.
9. Strainer – Always attach a strainer to bottom side of thesuction hose to prevent large objects and debris fromentering the pump. Strainer should be positioned so that itwill remain completely under water. Running the pump withthe strainer above water for long periods can damage pump.

Figure 4. Engine Controls and Components
INITIAL SERVICING
The engine (Figure 4) must be checked for proper lubrication andfilled with fuel prior to operation. Refer to the manufacturers enginemanual for instructions and details of operation and servicing. Theengine shown above is a HONDA engine, operation for othertypes of engines may vary somewhat.
1. Fuel Filler Cap – Remove this cap to add unleadedgasoline to the fuel tank. Make sure cap is tightenedsecurely. DO NOT over fill.
6. Choke Lever – Used in the starting of a cold engine, or incold weather conditions. The choke enriches the fuelmixture.
7. Air Cleaner – Prevents dirt and other debris from enteringthe fuel system. Remove wing-nut on top of air filtercannister to gain access to filter element.
8. Spark Plug – Provides spark to the ignition system. Setspark plug gap to 0.6 - 0.7 mm (0.028 - 0.031 inch) Cleanspark plug once a week.
9. Muffler – Used to reduce noise and emissions.
10. Fuel Tank – Holds unleaded gasoline. For additionalinformation refer to engine owner's manual.
Operating the engine without anair filter, with a damaged air filter,or a filter in need of replacementwill allow dirt to enter the engine,causing rapid engine wear.
2. Throttle Lever – Used to adjust engine RPM speed (leveradvanced forward SLOW, lever back toward operatorFAST).
3. Engine ON/OFF Switch – ON position permits enginestarting, OFF position stops engine operations.
4. Recoil Starter (pull rope) – Manual-starting method. Pullthe starter grip until resistance is felt, then pull briskly andsmoothly.
5. Fuel Valve Lever – OPEN to let fuel flow, CLOSE to stopthe flow of fuel.
NOTECAUTION - Fueling The Engine
Adding fuel to the tank should be done only whenthe engine is stopped and has had anopportunity to cool down. In the event of a fuelspill, DO NOT attempt to start the engine untilthe fuel residue has been completely wiped up,and the area surrounding the engine is dry.
Engine components can generate extreme heat.To prevent burns, DO NOT touch these areaswhile the engine is running or immediately afteroperating. NEVER operate the engine with themuffler removed.
CAUTION - Burn Hazard

Pre-Setup (Pump)
1. Read safety instructions at thebeginning of manual.
2. Place pump as near to water aspossible, on a firm flat, level surface.
3. To prime pump, remove fill cap (Figure 2) and fill pump casingwith water. If the pump casing is not filled with water beforestarting, it will not begin pumping.
QP-204H — PRE-SETUP (PUMP)
4. Check for leaks between pump and engine. If water is leakingbetween the pump and engine housing, the seal inside thepump may be worn or damaged. Continued operation of thepump is not recommended. Further usage of the pump underthese conditions may cause severe water damage to engine.
Hoses and Clamps
1. Check that all hoses are securely attached to the pump.Make certain suction hose (Figure 2) does not have any airleakage. Tighten hose clamps and couplings as required.
2. It is recommended that 2 clamps be used when securing thesuction hose to the inlet side (suction) of the pump.
3. Remember suction hoses must be rigid enough not tocollapse when the pump is in operation.
4. Check that the discharge hose (Figure 2) is not restricted.Place hose so that it lays as straight as it is possible on theground. Remove any twists or sharp bends from hose whichmay block the flow of water.
NOTESuction and discharge hoses areavailable from Multiquip. Contactyour nearest dealer for moreinformation.
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.
6. Make sure the suction strainer (Figure 2) is clean andsecurely attached to the water end of the suction hose. Thestrainer is designed to protect the pump by preventing largeobjects from being pulled into the pump.Pump casing must be filled with water before using pump.
Otherwise pump will not be able to begin pumping.
CAUTION - Pump Casing
DO NOT open fill cap if pump is hot!Water inside may be under pressure.The possibility exists of scalding,resulting in severe bodily harm.
WARNING - High PressureThe strainer should be positioned so it will remain completelyunder water. Running the pump with the strainer abovewater for long periods can damage the pump.
CAUTION - Strainer
CAUTION - Flammable Fluids-Chemicals
DO NOT pump flammable fluids, corrosive chemicals or fluidscontaining toxic substances. These fluids can create potentiallydangerous health and environmental hazards. Contact localauthorities for assistance.
CAUTION - Mechanical Seal
This pump uses a water-cooled mechanical seal to preventwater from seeping into the engine. The passage of waterthrough the pump casing lubricates the seal and prevents itfrom overheating. NEVER! operate the pump without waterin the casing as this will cause damage to the mechanicalseal.

QP-204H — MAINTENANCE (PUMP)
To perform the pump vacuum test do the following:
1. Remove the pump fill cap (Figure 2), and fill the pumpwith 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 18 (next page), place a water hoseinside the discharge opening of the pump, and turn onthe water. This flow of water into the discharge openingwill prevent the pump from running dry.
4. Place the Pump Vacuum Tester (P/N 7000030) overthe pump suction (inlet) opening (Figure 18) with thevacuum gauge facing upwards. It may be necessary toapply a small amount of water around the rubber seal ofthe vacuum tester to make a good suction fit.
5. Check and make sure that there are no air leaks betweenthe vacuum tester and the inlet port on the pump. If airleaks are present reset vacuum tester.
6. Run the pump for a few minutes while monitoring thevacuum gauge. If the gauge indicates a reading between-25 and -20 in. Hg. (inches of mercury) then it can beassumed that the pump is working correctly.
Pump Vacuum Test
25 in. Hg (inches of mercury)translates into 25 feet of lift at sealevel.
7. If the vacuum tester gauge indicates a readingbelow -20 in. Hg, it can then be assumed that the pumpis not functioning correctly, and corrective action needsto be taken.
8. To test the flapper valve, shut down the engine. Thevacuum tester should remain attached to the pumpsuction inlet port by vacuum. This indicates the pump'sflapper valve is seating properly to hold water in thesuction hose when the engine is stopped. This preventsbackflow and allows for faster priming when the engineis restarted.
NOTE
CAUTION - Pump Priming
DO NOT attempt to start the engine unless the pump haspreviously been primed with water. Severe pump damagewill occur if pump has not been primed.

QP-204H — PREPARATION FOR LONG -TERM STORAGE
Pump Storage
For storage of the pump for over 30 days, the following isrequired:
Drain the fuel tank completely.
Run the engine until the fuel in the carburetor iscompletely consumed.
Completely drain used oil from the engine crankcaseand fill with fresh clean oil, then follow the proceduresdescribed in the engine manual for engine storage.
Remove the drain plug from the pump and drain out anywater from left in the housing.
Remove the pump cover and clean inside of pumphousing. Coat inside of pump housing with a light film ofoil to reduce corrosion. A spray can of oil works well forthis application.
Cover suction and discharge ports with duct tape toprevent any foreign matter from falling into pump.
Cover pump and engine with plastic covering orequivalent and store in a clean, dry place.
To protect the water cooled-seals, place one-half pint oflubricating oil (new or used) through the discharge openingon the pump and crank the engine several times. Thiswill prevent excessive corrosion and also keep themechanical seal lubricated.
