Limited Warranty
STA-RITE warrants to the original consumer purchaser (“Purchaser” or “You”) of the products listed below, that they will be free
from defects in material and workmanship for the Warranty Period shown below.
Product Warranty Period
Water Systems Products — jet pumps, small centrifugal pumps,
submersible pumps and related accessories
whichever occurs first:
12 months from date of original installation,
or 18 months from date of manufacture

Our warranty will not apply to any product that, in our sole judgement, has been subject to negligence, misapplication,
improper installation, or improper maintenance. Without limiting the foregoing, operating a three phase motor with single phase
power through a phase converter will void the warranty. Note also that three phase motors must be protected by three-leg,
ambient compensated, extra-quick trip overload relays of the recommended size or the warranty is void.
Your only remedy, and STA-RITE’s only duty, is that STA-RITE repair or replace defective products (at STA-RITE’s choice). You
must pay all labor and shipping charges associated with this warranty and must request warranty service through the installing
dealer as soon as a problem is discovered. No request for service will be accepted if received after the Warranty Period has
expired. This warranty is not transferable.
STA-RITE SHALL NOT BE LIABLE FOR ANY CONSEQUENTIAL, INCIDENTAL, OR CONTINGENT DAMAGES WHATSOEVER.
THE FOREGOING WARRANTIES ARE EXCLUSIVE AND IN LIEU OF ALL OTHER EXPRESS AND IMPLIED WARRANTIES,
INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE FOREGOING WARRANTIES SHALL NOT EXTEND BEYOND THE DURATION EXPRESSLY PROVIDED HEREIN.
Some states do not allow the exclusion or limitation of incidental or consequential damages or limitations on the duration of an
implied warranty, so the above limitations or exclusions may not apply to You. This warranty gives You specific legal rights and
You may also have other rights which vary from state to state.
This Limited Warranty is effective June 1, 2011 and replaces all undated warranties and warranties dated before June 1, 2011.

California Proposition 65 Warning
This product and related accessories contain
chemicals known to the State of California to cause cancer, birth
defects or other reproductive harm.
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.
NOTICE: 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.
NOTICE: 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 counter-
clockwise.
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.
