Design
Highly efficient water-supply unit ready for connection (non self-priming) with 2 to 4 vertically arranged stainless steel high-pressure multistage centrifugal pumps in glanded version from the Helix V series switched in parallel, including Smart Controller SC (available with and without frequency converter FC)
Application
- Fully automatic water supply in inlet mode, in the field of public water supply, for pressure boosting from tanks or pressure pipes, for municipal, commercial, industrial and domestic applications (e.g. water supply companies, trade and industrial companies, residential, office or public facilities, administration buildings, hotels, hospitals).
- Pumping of drinking water and process water, cooling water, fire water (apart from fire-extinguishing systems in accordance with DIN 14462 and with the approval of the local fire safety authorities) or other types of industrial water that do not attack the materials either chemically or mechanically and do not contain abrasive or long-fibre constituents.
Equipment/function
- 2 – 4 pumps per system of the Helix V 4 to Helix V 52 series with IE3 standard motor, including 0.75 kW and larger (optional for smaller motor power)
- Automatic pump control via Smart Controller SC The Smart FC version is additionally equipped with a frequency converter in the switchbox
- Parts that come in contact with the fluid are corrosion-resistant
- Base frame made of galvanised steel, with height-adjustable vibration absorbers for insulation against structure-borne noise, cable guidance and an integrated lifting device
- Shut-off device on the suction and pressure sides of each pump
- Non-return valve on the pressure side of each pump
- Diaphragm pressure vessel 8 l, PN 16, pressure side
- Pressure sensor, pressure side
- Pressure gauge, pressure side
- Optional low-water cut-out switchgear with pressure gauge, suction side
