Modernization of pumps

Modernization method

Replacement of standard seals and frictionless bearings for bearing-sealing BPU type units, which include face seals, support and thrust plain bearings.

Realized projects

  • Modernization of oil console and chemical NK-type pumps.
  • Modernization of condensate pumps for TEC, including KSB 125-140, KS 125-140, KS 80-155.  
  • Modernization of double support D350 type pumps.
  • Modernization of the feeding pumps.  


The first pumps have been operated without overhaul since 1997, power consumption being reduced and pump vibroacoustic characteristics improved.
