phase the material moves outwards along the drum until it comes into contact 

with the wedge bar screen (3) or remaining layer of previously accelerated 

material. By building up an additional layer of material over the previous layer 

the old material is forced to glide over the screen and out from the centrifuge 

via the outlet for dry chips (4). During the time the material is exposed to the 

centrifugal force the liquid is separated from the solid particles. When the 

material passes over the screen the liquid goes through this and out from the 

centrifuge via the outlet for liquids (7). This outlet is located immediately 

behind the outlet for dry chips.

10  Maintenance

Read Chapter  ‘4 Safety’ before carrying out maintenance. 

Installation, repair and maintenance work is to be carried out by qualified 

personnel using only original Nederman spare parts. Contact your nearest 

authorized distributor or Nederman for advice on technical service.

NOTE! 

The service intervals in this chapter are based on the unit being 

professionally maintained.

10.1  Maintenance instruction

NEDERMAN Swarf Centrifuge is very robust in design but should like every 

other production machine be regularly checked and maintained. 
Daily checks should be made at the start of operations until a permanent 

maintenance schedule can be established. When this has been done only  

routine checks and general observations are necessary.
All parts coming into contact with the material which passes through the 

centrifuge are subject to wear. Negligent or delayed replacement of worn 

parts results in high repair costs and unsatisfactory separating of liquid. A 

maintenance schedule should therefore be established which also indicates 

when it is time to replace worn parts. This schedule may only be drawn up by 

you since wear is highly dependent upon the ingoing chip quality. A basic rule, 

however, is to check the screen, drum and housing once a month in the case of 

one-shift operations. Inspection takes place via the front door.

10.2  Lubrication

The Swarf Centrifuge has an automatic lubricator for the two roll bearings. The 

lubricator is on delivery filled with oil, Shell OMALA EP150 or equivalent.
Check the oil level in the container regularily (once a month) and fill 

additionally. Changing of oil must be done every six months during 1-shift 

operation.
A grease nipple is situated between the packing rings at the housing. 
On delivery Castrol N1-ENTGR-18K (NLGI 2) grease or equivalent has been 

used.
The greasing intervals should be adjusted to the operating intensity, there must 

always be grease between the packing rings.
