Technical Features
Design
Water-supply unit with a non-self-priming high-pressure multistage centrifugal pump and integrated speed control.
Application
- Fully automatic water supply in inlet mode, either from the public water supply network or from a tank.
- Pumping of drinking water, 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 MVIE series pump with infinitely variable control mode via integrated frequency converter
- All components in contact with the fluid are corrosion-resistant
- Check valve, pressure side
- Non-return valve, pressure side
- Diaphragm pressure vessel 8 l, PN16

Construction
- Base frame: Galvanised steel with height-adjustable vibration dampers for comprehensive insulation against structure-borne noise
- Pipework: complete pressure-side pipework made of stainless steel, suitable for the connection of all piping materials used in building services; the pipework is dimensioned according to the overall hydraulic performance of the pressure boosting system
- Pumps: 1 pump from the series MVIE 2.., 4.., 8.., 16.., 32.. or 52.. (up to max. motor power of 7.5 kW) is used; the adapted, air-cooled frequency converter on the pump motor enables continuous auto control between 25 Hz and a maximum of 65 Hz for all pumps of these series; all pump components in contact with fluid are made of stainless steel.
- Valves: the pump is fitted on the pressure side with a check valve with DVGW approval mark and a DVGW-approved non-return valve
- Diaphragm pressure vessel: 8 l/PN16 located on the discharge side with a butyl rubber diaphragm, completely safe in accordance with food safety laws; for testing and inspection purposes, with shut-off ball cock, with drain and throughflow fitting according to DIN 4807
Options
