MODEL EEDD-29 PUMP UNIT
ONLY
To mount pump to your engine, proceed as follows:
-
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.
-
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).
-
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.
-
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. -
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 Pack age 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.
- Remove the capscrews, Key No. 8, which hold the pump body to the engine adapter.
- The pump body can now be removed.
- A tap on the volute diffuser, Key No. 18, will enable you to remove it, exposing the impeller.
- Remove the impeller from the engine shaft by turning counterclockwise.
- Seal replacement. The shaft seal consists primarily of two parts, a rotating member and a floating seat.
CAUTION 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
- 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.
- 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)
- Clean polished surface of floating seat with clean cloth.
- Turn seal plate over so seal cavity is up. Clean cavity thoroughly.
- 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.
- 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)
- Reinstall seal plate.
- Inspect shaft to make sure that it is clean.
- Clean face of sealing washer with clean cloth.
- 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.
- 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 | Probable Cause | Remedies |
|---|
No water delivered or not enough
water delivered.| 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| 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

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.
