DO NOT START THE PUMP UNTIL IT IS FILLED 

WITH WATER.

14. STUFFING BOX - MECHANICAL SEAL

With the exercise of a few precautions a mechanical 

seal will furnish very satisfactory operation in pumps. 

Precautions which should be observed are:

 

1. Do not run the pump dry. The flat faces of the seal 

 

  are lubricated by the liquid being pumped.

 

2. Vent the seal housing if it is the high point in the 

   pump.

 

3. Purge the system thoroughly to remove welding 

 

  slag, scale, or dirt which may injure the seal 

 

  prematurely due to the abrasive condition of liquid.

15. INSTALLING A NEW MECHANICAL SEAL

CAUTION:

 this seal is a precision product and should be 

handled accordingly. Be especially careful not to scratch 

or chip the lapped sealing faces of the washer and floating 

seat. If reinstalling a used seal, both sealing faces should 

be relapped.

INSTALLING STATIONARY ELEMENT

The seat must be seated securely in the seat ring with 

the lapped face out. The 

unlapped

 face is marked and 

correctly assembled when shipped. Oil the seat ring with 

light oil and seat it firmly and squarely. If this cannot be 

done with the fingers, use a sleeve as shown in Fig. 5, 

inserting the cardboard shipping disc between the sleeve 

and the lapped face to prevent scratching sealing face.

INSTALLING ROTATING ELEMENT

Oil shaft with light oil. Shaft should be clean and polished 

smooth. Slide seal body on shaft (washer end first) and 

seat firmly. A sleeve as shown in Fig. 6 will facilitate this 

operation and prevent the rubber driving ring from pulling 

out of place as the seal body is slid along the shaft. 

Assembly of impeller automatically sets seal in proper 

position.

Make sure at all times, and particularly before final 

assembly, that both sealing faces are absolutely clean. 

Sealing faces should be oiled with clean, light oil.

NOTE: DO NOT USE PETROLEUM BASED PRODUCTS 

TO LUBRICATE EPT OR EPDM ELASTOMERS - USE 

ONLY WATER BASE LUBRICANT.

WARNING:

Do not work on this pump until you are sure the pump 

and associated piping are totally depressurized, and if 

pumping hot liquids that the temperature is safe to handle.

Be sure that electricity to the motor is shut off and locked 

out, or if the motor is to be tested while running that it 

is conducted by a qualified person and safe electrical 

procedures are followed.

To insure safety and a successful repair, if there is 

anything about the pump and motor you do not completely 

understand, contact your distributor or the factory for 

instructions.

BEARING LUBRICATION:

A #2 grease is recommended. Use a water resistant, 

nonfiberous grease. Lithium base greases are excellent 

and molydisulfide is acceptable. Approximately 1/2 ounce 

of grease, or a teaspoonful for bearings of small size, and 

a tablespoonful for larger sizes, is needed each time a 

bearing is relubricated.
