PUMPS

Max. flow: 400 gpm

Max. head: 800 feet (345psi)

Applications

• Water supply and pressure boosting
• Industrial circulation systems
• Process water
• Cooling water circuits
• Fire protection systems
• Washing stations
• Irrigation systems

Benefits

• 2D/3D laser-welded, efficiency-optimized hydraulics
• Standard IE2 IEC, 3-phase, 2-pole motor (IE3 motor on request)
• Thanks to their modular body (height and flange are adaptable), Helix pumps can be installed in existing piping systems.
• Helix V 22-52: Pressure sensor connections in the pump body enable simple monitoring and control of pump operation (optional for standard version, and included in versions for aggressive fluids).
• The entire Helix range is available with an X-Seal cartridge mechanical seal (with standard gasket) for fast, easy maintenance.
• Removable coupling (from 7.5 kW) enables mechanical seal replacement without motor removal
• The default position of the terminal box is oriented towards the suction flange. However, this can be changed if required.
• Intermediate bearings (Al203/CW) ensure long service life
• Corrosion-resistant shaft thanks to stainless steel bushing
• WRAS/ACS approval for all wetted parts
