Technical Features
Design
High-efficiency, water-supply unit ready for connection. With vertical stainless steel high-pressure multistage centrifugal pump in glanded version, incl. EC controller (Easy Controller).
Application
- Fully automatic water supply and pressure boosting in inlet mode, either from the public water supply network or from a tank, for domestic, commercial, industrial and municipal applications (e.g. residential, office, administration buildings, hotels, hospitals, trades, industry, water supply companies).
- Pumping of drinking water and process water, cooling water, fire water (apart from fire-fighting 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
- 1 pump of the Helix V series with IE3 standard motor, including 0.75 kW and larger (optional for smaller motor power)
- Components that come in contact with the fluid are corrosion-resistant
- Base frame made of galvanised steel, with height-adjustable oscillation absorbers for insulation against structure-borne noise
- Shut-off valve, discharge side
- Non-return valve, discharge side
- Diaphragm pressure vessel 8 l, PN 16, discharge side
- Pressure transducer, discharge side
- Pressure gauge, discharge side
- Optionally with low-water cut-out switchgear (WMS) with pressure gauge, suction side
- EC-control with IP54 plastic housing, consisting of an internal power supply unit, microprocessor, analogue and digital input and output modules
