ST42 - 22

Description
The ST42 - 22 out of tank 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 corrosive fluids with flowrates from 2 up to 4 m3/h and with a total head of up to 5.5 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 integrated extended 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
  • Design ultracompact
  • Dry run possible without damage to the pump
  • Robust and reliablet
  • High density version available on request (up to d=2m)
  • No overflow flow rate thanks to counterturbine

Typical applications

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