Application

  • Water supply and pressure boosting 
  •  Industrial circulation systems 
  • Closed cooling circuits 
  • Fire extinguishing systems 
  • Washing systems

Scope of delivery

  • Helix V high-pressure multistage centrifugal pump
  • Installation and operating instructions
  • Helix V 2 – 16 (version PN16 with oval flanges): Stainless steel counter flanges with the corresponding screws, nuts and gaskets

Options

  • Helix V pumps are available on request with various types of mechanical seals such as porous silicon carbide (Q7Q7) for cooling applications with water-glycol mixture or tungsten carbide/silicon carbide (UQ) for water treatment applications with pure water (conductivity below 3 µS/cm).
  • Helix V 2 ... 52 are available with Victaulic connections, Helix V 2 ... 16 are also available with Tri clamp connections (DIN 32676).
  • Both stainless steel variants (304 and 316L) can be offered with EPDM or FKM seals.
  • New IE4 motors in 50 Hz are available on request to save even more energy.

Your advantages

  • Efficiency-optimized, laser-welded 2D/3D hydraulics, flow and degassing optimized
  • Corrosion-resistant impellers, guide vanes and stage housings
  • Flow and NPSH-optimized pump housing
  • Maintenance-friendly design with particularly robust coupling guard
  • Drinking water approval for pumps with parts that come in contact with the fluid made of stainless steel (EPDM version)
