STN

Compact, Plastic and Fluoroplastic Magnetic drive Horizontal Centrifugal pumps

Materials: PP-GF (Polypropylene-Glass filled) - CFR-ETFE (Carbon Fiber filled - Ethylene tetrafluoroethylene)

Close-coupled execution

 

Versatility: The STN offer a wide range of materials for the wetted parts:

PP-GF (Polypropylene-Glass filled)

CFR-ETFE (Carbon filled - Ethylene tetrafluoroethylene) - *only casing

 

Reliability: Suitable for handling corrosive, aggressive and hazardous liquids (low viscosity, clean or slightly contaminated) in the chemical applications

 

Design: Made with a reliable quality as the ETN but designed for smaller applications or where the working condition are less critical
