Energy-efficient with high pressure – multi-stage plastic centrifugal pump with magnetic coupling

Single-stage centrifugal pumps are not very efficient at high pressure. For energy-efficient operation of centrifugal pumps in the high-pressure range, multi-stage centrifugal pumps are needed. This means several centrifugal pumps and impellers in series. In series operation, the feed levels get added.

The RM-MS achieves higher efficiency in the high pressure range than a single-stage centrifugal pump for larger volume flows, which runs in an unfavorable operating range and thus at low efficiency.

The well-thought-out and reliable design is convincing:
  • BEP (Best Efficiency Point) at high head and small flow rate
  • 1-, 2- and 3-stage versions
  • Compact, flexible and modular building block design
  • Excellent chemical resistance
  • Metal-free plastic version in PP or PVDF
  • Other materials, such as stainless steel on request
  • Environmental friendly due to hermetically sealed housing
Advantage over single-stage centrifugal pumps:
  • Small, compact design at high pressures
  • By adding the heads per stage, high pressures can be achieved at low flow rate and best efficiency.
