Operation PD 2A/3A

4. Operation

4.1 Application

This pump is intended for removing clean water or water containing a
large amount of debris and suspended solids. The model PD 2A can
pump water containing solids up to 30 mm (1.25 in.) diameter. The
model PD 3A can pump water containing solids up to 45 mm (1.75 in.)
in diameter.

Diaphragm pumps are ideal for pumping mud, slurries and seepage.
Typical applications include dewatering of trenches, sewers, pipelines,
septic tanks, holding tanks, farm ponds, fields and excavations where
a large amount of solids may be present in the water.

4.2 Recommended Fuel

The engine requires regular grade unleaded gasoline. Use only fresh,
clean gasoline. Gasoline containing water or dirt will damage fuel
system. Consult engine owner’s manual for complete fuel
specifications.

wc_tx000228gb.fm 18

Operation PD 2A/3A

4.4 Priming Pump

See Graphic: wc_gr001064

Diaphragm pumps are self priming and seldom need to have water
added to them before starting. However, if the pump has not been
used for several weeks and the rubber valves inside it are dry, adding
water through the surge chamber (f) will help the valves seal and
shorten the amount of time required for the pump to prime.

4.5 Before Starting

See Graphic: wc_gr001064

4.5.1 Read safety instructions at the beginning of manual.

4.5.2 Place pump as near to water as possible, on a firm, flat, level surface.

4.5.3 Check that hoses are securely attached to pump. Suction hose (c)
must not have any air leaks. Check that all hose clamps (b) and
couplings (a) are tight. Check that cap on surge chamber (f) is tight.

4.5.4 Check that discharge hose (e) is not blocked. Lay hose out as straight
as possible. Remove any twists or sharp bends from hose which may
block the flow of water.

Note: Operating the pump with any part of the discharge line
positioned higher than 7.5 m (25 ft.) above the pump can cause
backflow into the pump and damage pump components.

4.5.5 Make sure suction strainer (d) is clean and securely attached to end of
hose. The strainer is designed to protect the pump by preventing large
objects from being pulled into the pump.

Position strainer so it will remain under water as water level drops.

4.5.6 Check fuel level, engine oil level, and condition of air cleaner.

wc_tx000228gb.fm 20

Note: If engine is cold, move choke lever to close position (b1). If
engine is hot, set choke to open position (b2).

4.6.2 Turn engine switch to “ON” (e1).

4.6.3 Open throttle by moving it slightly to left (d1).

4.6.4 Pull starter rope (c).

Note: If the oil level in the engine is low, the engine will not start. If this
happens, add oil to engine. Some engines are equipped with an oil
alert light (f) that will come on while pulling the starter rope.

4.6.5 Open choke as engine warms (b2).

4.6.6 Open throttle fully to operate.

4.7 To Stop

See Graphic: wc_gr000014

4.7.1 Reduce engine RPM to idle by moving throttle completely to right (d2).

4.7.2 Turn engine switch to “OFF” (e2).

4.7.3 Close fuel valve by moving lever to the left (a2).

wc_tx000228gb.fm 21

Operation PD 2A/3A

4.8 Operation

Run engine at full speed while operating pump.
Pump should begin pumping water within a minute depending on

length of suction hose and height of pump above water. Longer hoses
will require more time.

If pump does not prime, check for loose fittings or air leak in suction
hose. Make sure strainer in water is not blocked.

DO NOT pump flammable fluids, fuels, corrosive chemicals or fluids
containing toxic substances. These fluids can create potentially

WARNING

dangerous health and environmental hazards. Contact local
authorities for assistance.

WACKER offers a complete line of fittings, hoses, and clamps to
properly connect the pump to match various job conditions.

PD 2A/3A Operation

4.10 Hoses and Clamps

See Graphic: wc_gr001065

Suction Hose

Suction hoses (a) must be rigid enough not to collapse when pump is
operating.

Discharge Hose

Discharge hoses (b) are usually thin-walled collapsible hoses. Rigid
hoses similar to those used as suction hoses may also be used as
discharge hoses.

Note: Suction and discharge hoses are available from WACKER.
Contact your nearest dealer for more information.

Suction Hose to Inlet Coupling

Two clamps (c) are recommended for connection of suction hoses to
inlet coupling.

Note: This connection is important. Even a small air leak on the
suction side of pump will prevent the pump from priming.

Other Hose Connections

For other hose connections, one T-bolt or worm-gear type clamp is
usually sufficient to hold hoses in place. In some cases, slight
variances in hose diameters may make it necessary to add more
clamps in order to maintain tight connections.

5.7 Cleaning Pump

See Graphic: wc_gr003451

When pumping heavy sludges or water containing large amounts of
dirt and solids, clean the pump often. If allowed to sit in the pump and
dry, these materials will harden and could damage the valves or
diaphragm inside the pump the next time it is used.

When cleaning pump:

5.7.1 Pump clean water through pump for a few minutes after each use to
flush dirt from inside pump and hoses.

5.7.2 Remove dirt from between engine cooling fins to prevent them from
clogging up. This will prevent engine from overheating.

5.7.3 Remove front cover (k) and clean dirt and grease build-up from
connecting rod and inside of front pump cover.

5.9 Carburetor Adjustment

See Graphic: wc_gr000032

5.9.1 Start the engine and allow it to warm up to operating temperature.

5.9.2 Set the pilot screw (a) two turns out. See Note.

5.9.3 With the engine idling, turn the pilot screw (a) in or out to the setting
that produces the highest rpm.

5.9.4 After the pilot screw is adjusted, turn the throttle stop screw (b) to
obtain the standard idle speed. See Technical Data.

Note: On some engines the pilot screw is fitted with a limiter cap (c)
to prevent excessive enrichment of the air-fuel mixture in order to
comply with emission regulations. The mixture is set at the factory and
no adjustment should be necessary. Do not attempt to remove the
limiter cap. The limiter cap cannot be removed without breaking the
pilot screw.

5.10 Storage

If pump is being stored for more than 30 days:

NEVER open priming plug, discharge plug, or cover when pump is hot.

WARNING

5.10.1 Remove discharge plug from pump casing and drain out any water left
in the housing after pump has cooled.

5.10.2 Remove pump cover and clean inside of pump housing. Coat inside of
