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
