Pump types
A stainless steel pump is a pump where the pump casing and fluid-carrying parts are made of stainless steel – typically AISI 304 or AISI 316. This makes it particularly suitable for liquids with low pH, high salt content or chemical exposure.
Stainless steel pumps are used where corrosion and material degradation can be a problem or where high hygiene is required, such as in the food industry, process plants or wastewater treatment.
Stainless steel pumps work just like any other pump – the difference lies in the choice of material:
Stainless steel protects against corrosion and chemical degradation
Withstands higher temperatures and aggressive liquids
Available as submersible pump, motor pump, electric pump or self-priming solution
Available with both open and closed impellers, depending on particle content and flow requirements
Many stainless steel pumps can be connected SRO systems for intelligent operation and monitoring.
Corrosion resistant – long service life even in harsh conditions
Suitable for aggressive and chemical liquids
Easy to clean and maintain
Reliable solution for both permanent and temporary installations
Available in compact or high-capacity versions
High-load wastewater treatment
Process water and chemicals in industry
Food production and pharmaceutical plants
Pumping seawater, salt water or acidic liquid
Drainage and pumping stations with long-term moisture impact
Stainless steel pumps are available in multiple configurations and steel grades:
Materials:
AISI 304: Good for most light corrosion applications
AISI 316: Acid resistant – suitable for highly aggressive environments
Pump shaper:
Submersible pumps in stainless steel
Electric centrifugal pumps
Self-priming pumps with stainless steel casing
Stainless steel gear pumps for viscous fluids
Optional extras:
Ex protection (ATEX)
Seals for chemical impact
Frequency control and level control
