Benefits

  • Robust design for long service life and low maintenance costs due to volute casing with double volute and centreline feet; robust and cost-effective component seal can be used across a wide pressure and temperature range.
  • High system availability due to intensive cooling of the seal chamber via replaceable high-efficiency cooling insert or tube-in-tube heat exchanger (if required).
  • Long service life (L10h over 17,500 hours) and high reliability of the bearings ensured by optimised shaft, individual selection of the balancing holes and angular contact ball bearings in triple arrangement, dimensioned for high inlet pressures.
