Helix V
Multistage in-line pump
High efficiency and long service life for large buildings and other demanding fields of application.
- IE3/IE4 fixed-speed motor ensures high efficiency
- All components that come in contact with the fluid are corrosion-resistant, made of laser-welded or cast stainless steel (AISI 304/AISI 316L)
- Among other things, the gasket types and pump connections (oval flanges, round flanges to ISO, Victaulic or Triclamp connection) are versatile and configurable for specific applications.
- Maintenance made easy through convenient access to pump components (such as the bearing integrated in the lantern), the wide range of motor compatibility, and the spacer coupling and cartridge mechanical seal (if used)
- Suitable for high-temperature environments with a standard ambient temperature of up to 50 °C without power dissipation
- Drinking water approval if EPDM rubber is selected for the gasket
