4.2.2  Pump 

1.  Remove  dust  caps  from  drive  end  and  inspection  end 

bearing housings. 

2.  Remove  lockwashers  and  locknuts  from  both  inspection 

end and drive end of shaft. 

3.  Remove  both  bearing  housings.  (To  remove  bearing 

housing, screw two of the bearing housing setscrews into 
the tapped holes provided in the bearing housing. Evenly 
tighten  the  setscrews  to  withdraw  the  bearing  housing.) 
Take care not to damage the mechanical seal faces. 

4.  Press out the ball bearings from the bearing housings. 

5.  Remove  the  bearing  dampening  O-Rings  from  the  shaft 

then  carefully  remove  the  mechanical  seal  components 
from  both  the  bearing  housings  and  from  the  rotor/shaft 
assembly. 

6.  Remove  body  covers  and  wearplates  (To  remove  body 

cover,  screw  four  of  the  bearing  housing  setscrews  into 
the  tapped  extraction  holes  provided  in  the  body  cover. 
Evenly tighten the setscrews to withdraw the body cover.) 

7.  Withdraw  the  rotor/shaft/vane  assembly  from  the  body 

taking  care  to  support  the  vanes  as  the  assembly  is 
withdrawn. 

8.  Remove  vanes  and  pushrods  from  the  rotor  (note  the 

orientation  of  the  vanes  relative  to  the  direction  of 
rotation) 

9.  Remove liner from body (note the orientation of the liner 

relative to the inlet and discharge ports of the body. 

10. Remove grease nipples and pressure release plugs from 

the bearing housings. 

11. Remove oil seal from drive end dust cap.

INSPECTION 

NOTE:

 

Optimum 

performance 

is 

achieved 

by 

maintaining 

the 

pump 

within 

the 

following 

guidelines.  

Adequate  performance  may  still  be  achieved 

dependent on application parameters

1.  Inspect  rotor/shaft  assembly  and  liner.    If  damage  or 

excessive wear is evident, it is recommended to replace 
both components. Scoring in the seal zones of the liner is 
detrimental to optimum performance. 

NB:

 The rotor is permanently attached to the shaft. 

2.  Inspect both mechanical seals. Replace mechanical seal 

assembly if components are worn or damaged  

3.  Inspect  vane  pushrods  for  wear,  damage  and 

straightness. Replace the pushrods if they show signs of 
physical  damage,  wear  or  distortion  e.g.  mushroomed, 
rounded  or  tapered  ends,  scoring  on  flanks,  bending, 
etc. 

4.  Inspect vanes for wear or damage. Replace if damaged 

or excessive wear is evident. Check for scoring on vane 
tips.

5.  Inspect  pressure  relief  valve  assembly  and  components 

for wear or damage.  Replace or refurbish as required. 

6.  It  is  recommended  that  all  O-Rings  and  lip  seals  be 

replaced at every overhaul. 

7.  Inspect  both  ball  bearings  for  wear.  It  is  recommended 

on major overhauls that ball bearings be replaced. 

 

8. 

Ensure pressure relief ducts in bearing housings are not 

obstructed

 

4.4 

SPARE PARTS 

1.  When  ordering  spare  parts,  to  ensure  a  minimum  of 

delay  and  correct  replacement  to  original  specification, 
ALWAYS quote the pump Serial Number located on the 
nameplate of the pump. 

2.  Advise  the  name,  Cat  #  and  quantity  required.    Refer 

Section 5 

– Parts Designation. 

3.  Advise  complete  delivery  instructions,  transportation, 

etc. 

NOTE:

  Substitute  or  so-

called  ‘equivalent’  item/spare 

parts are not recommended for use.  

Compliance,  safe  operation  and  pump  performance 
may be severely compromised if incorrect or substitute 
spare  parts 

–  including  Fasteners,  O-Rings,  Ball 

Bearings, etc 

– are used.  

Only use genuine Ebsray spare parts. 

 

4.5 

REASSEMBLY - PRELIMINARY 

1.  Ensure  all  parts  are  clean  and  deburred  before 

assembly. 

At all times when handling and 
installing  mechanical  seals, 

care  must  be  taken  to  ensure  lapped  faces  and  seats 
are not damaged.  Particular attention must be given to 
carbon seats to prevent marking or chipping. 

 
2.  Lubricate  all  O-Rings  and  lapped  faces  of  mechanical 

seals  with  a  good  quality,  compatible,  detergent-free 
light oil before assembly. 

3.  Pack Ball Bearings with a good quality, suitable grease. 

4.  Ensure  correct  orientation  of  components  relative  to 

pump rotation/handing . 

CAUTION

DANGER 

Ball  Bearing  Replacement  interval  should  not  exceed 

V2000 

10,000 operational hours 

 

V3000 

  5,000 operational hours 

 

V3010 

  5,000 operational hours
