*Advantages:

Rugged system with Helix VE series stainless steel high pressure multistage centrifugal pump with integrated frequency converter

Proportional wide control range from 25 Hz to up to 60 Hz

The whole system is pressure loss optimized

Integrated dry-run detection with auto-deactivation via engine control electronics

Maximum control using the SCe controller with LC display, simple navigation and configuration using the knob

*Design:

The highly efficient water supply unit is ready to be connected (no self-priming). With 2 to 4 Helix VE series stainless steel high pressure centrifugal pumps arranged vertically in parallel converted route version; each pump is equipped with a built-in air-cooled inverter, included. Smart controller SCe
