MODEL EEDD-29 PUMP UNIT ONLY
To mount pump to your engine, proceed as follows:
1. Loosen clamp assembly (Key No. 4C) on shaft extension.
Position pump adapter on motor; insert engine shaft into shaft
extension. BE SURE pump adapter pilot fits pilot bore in engine.
2. Attach pump adapter to engine using (4) 5/16 x 3/4” capscrews
and lockwashers–(5/16-24 capscrews are required for engines
with aluminum blocks, and 5/16-18 capscrews are required for
engines with cast iron blocks).
3. Push shaft extension toward pump until fibre spacer will not rotate
freely on shaft. Tighten clamp assembly on shaft extension. Hold
the shaft extension with a screwdriver in one of the slots while
tightening the nut.
4. As the fibre spacer is used to establish impeller clearance only, it
will burn out shortly after pump is put into operation and need not
be replaced.
NOTE: If engine is removed, a new fibre washer should be
obtained to re-establish clearance before replacing engine.
5. Use one of the following engines:
(a) Briggs and Stratton
(b) Kohler
(c) Tecumseh
Refer to engine manufacturer’s service manual for parts or service
to engine.
BE SURE to fill crankcase with recommended grade of oil.
Do NOT run pump until it has been primed, as this could ruin
the seal.
NOTE: MODEL EDG-105 IS BUILT FOR USE WITH SWIMMING
POOLS.
MODEL EDG-105 IS SHIPPED WITH A 1-1/2” SUCTION FLANGE
ASSEMBLY.
* These parts are not furnished. Order Strainer Fittings Package
C298-9, which includes these parts.
PLACING THE PUMP
This pump is portable, and should be placed on a level foundation or
firm level ground as near the water source as possible, for efficient
operation. Model EEDD-29 can be mounted on an available gasoline engine. It must have the engine supported to the same level as
the pump mount, to avoid placing strain on the pump adapter or
engine. All suction and discharge piping should also be supported
independently near the pump, to avoid strain on the unit. Standard
piping can be used, or as the pump is portable, reinforced suction
hose can be used on the suction inlet. This hose must have the
equivalent capacity of 2” iron pipe. A strainer should be used on the
end of the suction pipe or hose. See Figures 1 and 2 for typical
installations.
PRIMING THE PUMP
Install pipe tee in the discharge opening of the pump with a nipple.
Provide a priming plug in the top opening.
See Figure 2.
Fill the pump with water and tighten the priming plug. Start the
engine, and the pump will prime, with priming time depending upon
the suction lift and the horizontal distance to water.
OPERATING SPEED
Models With Engine
These pumps leave the factory with a gas engine set to operate at
3500 rpm when pumping, which is the correct speed for maximum
efficiency. Model EEDD-29 must be provided with an engine which
will operate at approximately the same speed (3500 rpm).
Always start the unit at full speed until unit is primed and pumping
water. It can be throttled to lower the pump’s capacity while pumping.

PUMP SERVICE
Due to the simple, rugged construction of the pump, it should require
little service. However, if it should be necessary to replace a part, the
following procedure should be used.
1. Remove the capscrews, Key No. 8, which hold the pump body to
the engine adapter.
2. The pump body can now be removed.
3. A tap on the volute diffuser, Key No. 18, will enable you to remove
it, exposing the impeller.
4. Remove the impeller from the engine shaft by turning counterclockwise.
5. Seal replacement. The shaft seal consists primarily of two parts,
a rotating member and a floating seat.
The highly polished and lapped faces of this seal
are easily damaged. Read instructions and handle the seal with
care.
Some models are equipped with an impeller screw, which has a left
hand thread. Before unscrewing the impeller, remove the impeller
screw.
Removal of Old Seal
1. After unscrewing impeller, carefully remove rotating part of seal
by prying up on sealing washer, using two screwdrivers (see
Figure 3A, below). Use care not to scratch motor shaft.
2. Remove seal plate from motor and place on flat surface, face
down. Use a screwdriver to push ceramic seat out from seal cavity (see Figure 3B, below).
Installation of Floating Seat (Figure 3C)
1. Clean polished surface of floating seat with clean cloth.
2. Turn seal plate over so seal cavity is up. Clean cavity thoroughly.
3. Lubricate outside rubber surface of ceramic seat with soapy water
and press firmly into seal cavity with finger pressure. If seat will
not locate properly in this manner, place cardboard washer over
polished face of seat and press into seal cavity using a 3/4” socket or 3/4” piece of standard pipe.
4. Dispose of cardboard washer. Be sure polished surface of seat is
free of dirt and has not been damaged by insertion.
Installation of Rotating Part of Seal Unit (Figure 3D)
1. Reinstall seal plate.
2. Inspect shaft to make sure that it is clean.
3. Clean face of sealing washer with clean cloth.
4. Lubricate inside diameter and outer face of rubber drive ring with
soapy water and slide assembly on motor shaft (sealing face first)
until rubber drive ring hits shaft shoulder.
5. Screw impeller on shaft until impeller hub hits shaft shoulder. This
will automatically locate seal in place and move the sealing washer face up against seat facing. Reinstall impeller screw (if used).
MAINTENANCE
Be sure to drain pump during freezing weather to prevent damage
from frost. To drain, remove drain plug directly below the suction
inlet of the pump; also remove the priming plug. Drain the suction
pipe at a point below the frost line. All pipe exposed to freezing temperatures should also be drained. Before restarting pump, replace
all connections and plugs and reprime.
For service and maintenance to the engine, see the booklet which
comes with the engine.

TROUBLE – CAUSES AND REMEDY
Trouble
No water delivered or not enough
water delivered.
Probable Cause
Pump not primed
Speed too low
Suction line clogged
Suction lift too high
Air leak in suction line
Impeller plugged
Suction end not submerged deep
enough
Remedies
Fill pump body with water
Pump should operate about 3500
RPM - Check engine
Clean suction screen
Put pump closer to water
Tighten connections or replace with
new hose or pipe
Use pipe compound to seal all male
threads
Clean impeller
Submerge suction hose or piping
enough so that no air enters while
pump is operating
