DISASSEMBLY:
1. Separate motor from pump by unscrewing collar, (8) from motor. Gently pull pump from motor.
2. Remove retaining ring (15) from lower head. Remove screw (16) and set aside
3. Place a wide screwdriver in coupling spider (6) to keep it from turning and unscrew impeller (5)
(left hand thread) using a screwdriver between two of the vanes of the impeller.
4. Remove coupling spider (6) by lifting out.
5. Hold coupling (7) to prevent rotation Insert a small screwdriver in the slot of coupling shaft (14)
and unscrew coupling
6. Unscrew ball bearing housing (17) from pump and remove complete assembly. including shaft,
from pump.
7. Place a small screwdriver in slot of coupling shaft (14) and, using a small pair of pliers, grip
shaft (2) just below the ball bearing housing (17). Unscrew pump shaft.
8. Insert the head of a small common nail into the bearing retainer (4). Hook the back end of
bearing retainer and pull it out along with the bearing (3)
9. Before dismantling ball bearing housing (17) inspect ball bearings (11) as follows: Grasp
coupling shaft (14) and rotate ball bearing housing (17) by hand slowly. Rotation should
be absolutely smooth with no roughness. If continued operation is questionable, replace ball
bearings (11).
NOTE: These ball bearings are lubricated with special grease. Replace with original factory
quality parts only. We strongly recommend that you replace ball bearings and seal together as
a complete assembly with coupling shaft. See item 14. Otherwise see ball bearing and seal
replacement instructions below.
BALL BEARING and SEAL REPLACEMENT:
1. Remove retaining ring (10) from both ends of ball bearing housing (17).
2. Remove bearing housing components by pushing out coupling shaft (14) and ball
bearings (11) simultaneously
3. While supporting a ball bearing (11) and seal (13), remove from coupling shaft (14)
4. Repeat step 3 for other ball bearing (11).
5. Replace ball bearings by pressing on to shaft in the same manner in which they were first
removed .
6 Once ball bearing (11) and seal (13) are located on coupling shaft (14), press entire
assembly into bearing housing (17) and install retaining rings (10).
REASSEMBLY:
(1) To assemble bearing (3) to bearing retainer (4), insert bearing into 3/8 inch diameter end of
bearing retainer and pull 1" of bearing through slot Wrap 1" end of bearing (3) onto bearing
retainer (4) for 3/4 of one turn. Bearing must be wrapped on the mid section of bearing retainer
so as not to interfere with shoulders at each end.
2. Install bearing (3) and bearing retainer (4) assembly into pump tube (1)
3. Screw shaft (2) into coupling shaft (14).
4. Carefully guide the shaft (2) into the center of pump tube (1) without force. Then secure ball
bearing housing (17) by screwing into pump tube
5. Install coupling (7) onto coupling shaft (14).
6. Insert coupling spider (6) into coupling (7).
7. While holding coupling spider (6), install impeller (5) onto shaft (2) (left hand thread) tighten
impeller using a screwdriver between two vanes of the impeller.
8. Install screen (16) and retaining ring (15) into pump tube (1) tighten impeller using a screwdriver
between 2 vanes of the impeller.

1. KNOW YOUR UNIT—Read owners manual carefully. Learn its
applications, limitations, capabilities and proper use.
2. HAZARDOUS LOCATIONS—Use hazardous duty motor in
locations where fire or explosion hazards may exist due to
flammable gases or vapors. Use air motor in a dust environment.
Use stainless steel pump for flammable liquids.
3. KEEP WORK AREA CLEAN—Cluttered areas and benches invite
accidents.
4. AVOID DANGEROUS ENVIRONMENT—As with any electric
power tool, don’t expose the unit to rain.
5. KEEP BYSTANDERS AWAY—All visitors and unauthorized
persons should be kept a safe distance from work areas.
6. STORE PROPERLY—As with any power tool, when not in use,
unit should be cleaned and stored in a dry place away from
unauthorized personnel.
7. DON’T FORCE TOOL—Do not use pump to break ice in drums or
break up sludge masses. Rapid wear and/or damage will occur
when pumping abrasives or thick materials.
8. WEAR PROPER APPAREL—No loose clothing or jewelry to get
caught on hoses or cords. Rubber gloves, aprons and footwear
are recommended.
9. USE SAFETY GLASSES— The operation of
any power tool can result in foreign objects
(splashing) being thrown into the eyes, which
can result in severe eye damage. Always wear
safety glasses with eye shields before com-
mencing power tool operation. We recommend
Wide Vision Safety Mask for use over
spectacles, or safety glasses.
10. DON’T ABUSE CORD—Never carry tool by
cord or yank it to disconnect from receptacle. Keep cord from heat
and sharp edges .
11.SECURE PUMP AND HOSE—When not pumping from a drum,
secure pump to prevent accidental immersion into tanks. Secure
discharge end of hose to prevent “whipping” of hose.
Secure hose clamp tight.
12.DO NOT IMMERSE—pump into fluid above pump discharge.
Do not immerse motor in any fluid.
13. DON’T OVERREACH—Keep proper footing and balance at all times .
14.MAINTAIN EQUIPMENT with care — Keep pump clean for best
performance. Follow maintenance instructions.
15. DISCONNECT MOTOR—when not in use and before servicing,
remove plug from power supply.
16. AVOID ACCIDENTAL STARTING—Don’t carry plugged-in tool
with finger on switch. Be sure switch is off when plugging in.
17. KEEP HANDS AND FINGERS FROM IMPELLER.
18. KEEP FACE AWAY—Don’t look into hose, pump discharge or
suction.
19. REVIEW MATERIAL SAFETY DATE SHEET OF THE PRODUCT
TO BE PUMPED
.
INTRODUCTION
DOUBLE INSULATION is a concept in safety, in electric power tools,
which eliminates the need for the usual three wire grounded power
cord and grounded supply system. Wherever there is electric current
in the tool there are two complete sets of insulation to protect the user.
All exposed metal parts are isolated from the internal metal motor
components with protecting insulation.
IMPORTANT — Servicing of a motor with double insulation requires
extreme care and knowledge of the system and should be performed
only by a qualified service technician. For service, we recommend
returning your motor to Sethco.
HAZARDOUS DUTY MOTOR — When service is required, return to
factory. NOTE: This motor is equipped with a thermal overload sen-
sor. When activated the pump will stop and re-start automatically
when the motor cools.
Problem: Pump capacity reduced
1.
Worn impeller and/or suction intake 1. Replace
2. Low voltage 1. Check outlet
3. Thick fluids 1. Consult factory
4. Hose crimped 1. Straighten
5. Pump bearings worn 1. Replace
6. Motor bearing worn 1. Return to factory
7. Suction partially clogged 1. Unplug motor and clean
8. Discharge line restricted 1. Unplug motor and clear
CAUTION: Read rules for safe operation and instructions carefully
WEAR YOUR
SAFETY GLASSES
SWITCH
The standard 115V & 230V electric P90 motor is equipped with a
rocker switch located in the upper part of the handle. Press the upper
part of the rocker to start and the opposite half to stop. The switch
has a built in circuit breaker which will trip the switch in the event of
an overload. Be sure switch is in the “off” position before connecting
to power supply.
SWITCH
The hazardous duty motor is equipped with a rotary switch. Make sure
the switch is in the “off” position before connecting to power supply.
OPERATION
1. Align coupling splines and motor spline.
2. Align motor key and pump head.
3. Insert pump head into motor and secure with collar (1).
4. Slip hose clamp over hose end.
5. Slip hose onto pump discharge. Push hose onto full length of
discharge nipple. (1-1/8 inches).
6. Align hose clamp between discharge nipple “barbs”.
7. Tighten hose clamp.
START-UP (CAUTION — OBSERVE SAFETY RULES)
1. Insert pump into drum. 2. Control or secure discharge hose.
3. Plug in motor. 4. Switch unit on.
STOPPING
1. Switch unit off. 2. Unplug motor.
3. Lift pump from fluid slowly; allowing pump to drain.
STORAGE
1. Run pump in a rinsing solution for 30 seconds with discharge hose
open and 30 seconds with discharge hose closed.
2. Allow pump to drain.
3. Store in a secure area to prevent unauthorized use.
MAINTENANCE
When servicing, replace with original factory quality parts only. Only
the parts shown in the materials list are intended to be replaced by
the customer. The standard 115V & 230V motor is equipped with a
“DOUBLE INSULATION” system and should be serviced only by a
qualified service technician.
