Transferring and Filtering of Chemicals, Plating

Solutions, Pharmaceuticals, Cosmetics and Farm

Chemicals, Emptying and Filling Carboys, Vats, Tanks,

Barrels or Entire Systems.

OPERATING INSTRUCTIONS

INSTALLATION - Pump may be installed in any position.

Rotation of motor determines the location of the pump

intake. The motor is normally wired for clockwise rotation

when looking at pump cover, with inlet port on the right.

SELF-PRIMING - Vertical, dry suction lift of 10'. Pump

will produce suction lift up to 22' when wet. BE SURE

SUCTION LINES ARE AIRTIGHT or pump will not self-

prime.

DISCHARGE - When transferring liquids further than

25', use I" ID discharge Iine.

RUNNING DRY - Unit depends on liquid pumped for

lubrication. DO NOT RUN DRY FOR MORE THAN 30

WARNING

!Explosion hazard. Do not use where flammable

vapors are present. Do not pump solvents,

thinners or gasoline. To do so can cause an

explosion which can result in injury or death.

SERVICE INSTRUCTIONS

DISASSEMBLY

TO REPLACE IMPELLER

1. Remove end cover cap screws, end cover, gasket

and wearplate.

2. Grasp impeller hub with water pump pliers and with-

draw impeller from body. Check seal and internal

parts, for wear. Replace worn parts if necessary.

TO REPLACE SEAL ASSEMBLY

3. Loosen adaptor clamp nut and remove pump head

from motor Use a screwdriver to spread the clamp

slighty to facilitate removal.

4. See above Step #1.

5. Remove body, gasket and wearplate from adaptor.

Push impeller from body bore.

6. Remove seal liner and seal by pressing from motor

end of adaptor.

7. Remove seal from liner. Check all parts for wear.

Replace if questionable.

ASSEMBLY

TO REPLACE IMPELLER

1. Coat body bore and end of impeller extended insert

with a light film of water pump grease. Align detent

in impeller extended insert with keyway in shaft.

Depress the two impeller blades which fit under the

cam, and carefully push the impeller into the body

bore. Use a screwdriver in the drain slot area to push

the neoprene slinger up onto the end of the extended

impeller. Rotate the impeller in a clockwise direction

to assure the impeller blades are in the correct

position for easy starting.

2. Replace wearplate, gasket, end cover and

secure with end cover cap screws.

TO REPLACE SEAL ASSEMBLY

3. Install seal liner in bore of adaptor, aligning bolt

holes carefully.

4. Dip seal in water for lubrication and push into seal

liner bore with lip facing outwards. Wipe a thin film of

grease on lip of seal.

5. Install wearplate against liner, install gasket, align

bolt holes.

6. Push the impeller into the body and rotate the

impeller in a clockwise direction to align blades for

correct direction of rotation. Place the body impeller

assembly over the gasket and wearplate, and

carefully insert the impeller extended insert through

the seal.

7. Install the four capscrews through the adaptor flange

and screw into threaded holes in body flange.

Tighten bolts evenly and securely.

8. Repeat Step #2.

9. Align the tab in the slinger bore with the keyway in

the shaft and push the slinger part way onto the

shaft.

10. Align the detent in the impeller extended insert with

the keyway in the shaft and push the pump head

onto the motor hub, firmly against the motor. Tighten

the adaptor clamp nut just enough to prevent the

pump head from turning on the motor hub. If too

tight, motor bearing will seize the shaft and become

damaged during operation. Attach short lengths of

hose to suction and discharge ports and place both

hose ends in a bucket of water, before plugging

motor in, to check operation.
