Twin-screw pumps

Twin-screw pumps

CHEMSPIN INLINE – choice of couplings for simple change to twin-screw pumps

CHEMSPIN twin-screw pumps are available with different coupling orientations. INLINE versions with parallel couplings are available for pipes with continuously vertical or horizontal runs.

These versions permit simple replacement of rotary lobe or rotary piston pumps with CHEMSPIN twin-screw pumps.

CHEMSPIN twin-screw pumps can be mounted

• horizontally

• vertically upwards or downwards

• sideways to a wall

Advantages at a glance
  • Low space requirements   
    Thanks to the oppositely located couplings, the pumps can be mounted easily into existing plants.
     
  • Very high flexibility
    Many different products and a wide range of flow quantities and viscosities can be handled by a single pump. Reverse operation is possible – the range of different pumps in a plant can be reduced considerably.
     
  • Safe operation
    Loaded, abrasive or lumpy media can be conveyed – a suitable shaft seal can provide dry-run protection. Very low vibration and noise levels.
     
  • Low cavitation risk
    The CHEMSPIN exhibits very low NSPH values. This applies for the full operating range, also for operating points close to zero throughput. Increasing pump speeds and viscosities only have a limited effect.
     
  • Self-priming, able to handle entrained gas
    Outstanding suitability for emptying & transfer pumping operations.
     
  • High chemical resistance
    The CHEMSPIN is made of 1.4404 stainless steel as standard. Hardened pumping elements and contactless operation ensure high wear resistance.
