ST50 - 30 - 10

The ST50/30/10 immersed vertical pump range benefits from proven design features gained through over 60 years of experience and developments, and has been specially designed to handle the transfer of industrial and corrosiv fluids for flowrates from 1 up to 5m3/h and with a total head of up to 7 meters.

The innovative design integrates an internal stainless steel structure overmolded with plastic (PP or PVDF) which eliminates weak shaft connections whatever the temperature or liquid nature.

The chemical duty motor with monobloc SS shaft ensures a great alignment of the impeller, the unique hydraulic part (closed impeller + innovative diffusor) has been enhanced through numerical simulations to improve hydraulic performances in comparison to existing pumps.

All those innovations allow the pump to reach incredible efficiency. All our pumps are individually tested in order to ensure proper operation and hydraulic performances.

Highlights

  • High efficiency : 20% higher than the market average pumps
  • Important energy savings
  • Improves productivity through enhanced hydraulic performances
  • Quiet and vibration free operation
  • Ultracompact design
  • Dry run possible without deteriorations
  • Sturdy and safety of operation
  • High density version available on request (up to d=2m)

Typical applications

  • Electroplating baths, rinse bath, acids, alkalis, chemically contaminated fluids, corrosive media and effluents
  • Works in the bath only (a version that works outside of the tank is also available)
