STN – Plastic and fluoroplastic magnetic drive horizontal centrifugal pumps

Category Brand

Description

The STN pumps are 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

PRODUCT CHARACTERISTICS

  • 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
