Installation procedure of packing 

 

 

1. Cut packing 
 

You should wind the packing around the 
shaft and cut a little longer about half of 
the packing width from a butt joint. 
 
  length of packing(L)=π(D+4/3 W) 
    (D: shaft bore diameter, W: packing 
  width) 
 
Please make sure the butt joint of the   
packing in cutting. 

 
 
2. Insert packing 
 

Please confirm you can insert the packing 
smoothly by butting joint of the packing   
ring as arching the back. Please insert one   
ring into the stuffing box if you confirm 
you can insert smoothly. You should 
compress the inside of stuffing box, 
because of increasing sealing performance, 
and not providing packing unreasonable 
surface pressure by rounding together of 
rings. 
You need the packing fitted the shaft by   
compressing inside part of the stuffing 
box in inserting rings because surface 
pressure of each of packing rings in the box 
tend not to decrease as more inner side in 
case of cramping the packing by packing 
gland. 
Joint of rings should be staggered and kept 
120 degree apart. 

 
3. Tightening packing 
 

After the last rings is installed, you should 
bring the follower down on the packing and 
finger-tighten the gland nuts. 
Please pay attention that gland bolts are 
tightened evenly and a gland do not touch 
with shaft or sleeve. 
(Stopping leakage entirely at this point will 
cause the packing to burn up.)

4. Adjustment of running 
 

You will start operating the packing after finish inserting packing rings. 
You should operate with confirming the condition through the irrigation, making sure to the air vent 
cock and valve, signing the operation with checking each part and not to mistake screwing the valve. 
After start of operating, you should continue initial operation with paying attention to amount of 
leakage, heat, and noise of the gland, removing air in the pump.   
Amount of leakage is as the following

 

list. 

You should not set amount of leakage to zero after start of operates. You need to take care of initial 
operate due to easy development of heat. 
Stable operate could start after 15 to 20 minutes of initial operate. You need to pay attention to tighten 
the gland nuts after stable operate.

DISMANTLEMENT AND ASSEMBLY OF THE TYPE 

CRD 

DATE 

28 SEP. 2009 

 

 

This type should be dismantled and assembled according to the next order with referring 

the assembly drawing. (Refer to 98DS0043/A1DS0538/A1DS0539/A5DS0143) 

 

1. Remove the bolt of the pump suction flange and the discharge flange. 

2. 

Remove the casing cover (002) from casing (001). O ring (050) attention. 

3. 

Remove the impeller nut (120).   

4. Remove the spring washer (821/9) and the impeller washer (124). 

5. Remove the impeller Remove the impeller (003). 

6. Remove the sealing water pipes. (CRD-50 is excluded. ) 
 
* In case of CRD-50, 65, and 80 

7. Remove the casing (001) from the frame (404), and pull out each mechanical seal. 

8. Remove the floating seat from the casing (001). 
 
* In case of CRD-100, 100-2, 100-3, and 125 

7. Remove the bolt, and seal cover (521) is removed. 

8. Remove the casing (001) from the frame (404). 

9. Loose the set screw of mechanical seal (9). 

10. Remove the seal ring of mechanical seal (520). 

11. Remove the seal cover (521) from shaft (101). 

12. Remove the floating seat from seal cover (521). 
 

The entire pump is assembled in the reverse order of the pump resolution.

 

 
 
Attention of Assembling 
 

・Please do not damage sealing surfaces when you install the mechanism seal. 
・Apply lubricating oil of ISO No. VG32-VG68 or equivalent. 
・The seat cup (2) firmly at the bottom in the seal cover. (So as not to beat with the hammer. ) 

 
(Please make sure that assembling will be completed within 30 minutes as bellows of this type of 
mechanical seal will get stuck onto the pump shaft. )
