Installation and Operating Instructions  »

Water-supply unit with a non-self-priming high-pressure multistage centrifugal pump and integrated speed control

  • Fully automatic water supply in intake mode, either from the public water supply network or from a tank
  • Pumping of potable water, process water, cooling water, water for fire-fighting or other water mixtures that do not chemically or mechanically attack the materials used and do not contain abrasive or long-fibre constituents
Special features/Product advantages
  • Heavy-duty system due to MVIE and Helix VE series stainless steel high-pressure multistage centrifugal pumps with air-cooled integrated frequency converter
  • Wide hydraulic range through the use of all pumps in the MVIE and Helix VE series
  • Frequency converter with superproportionally large control range
  • Integrated full motor protection via PTC
  • Integrated dry-running detection with automatic deactivation in the event of low water through the use of the performance characteristics of the motor control electronics

Description/Design
  • Base frame: 1.4301 stainless steel or galvanized steel (MVIE.../VR) with height-adjustable vibration dampers for comprehensive insulation against structure-borne noise
  • Pipework: Complete pressure-side pipework made of 1.4571 stainless steel, suitable for connection of all commonly used piping materials; the pipework is sized corresponding to the overall hydraulic performance of the pressure boosting system
  • Pumps: 1 pump is used from each of the series MVIE 2.., 4.., 8.., 16.., 32.. or 52.. (motor power up to max. 7.5 kW); the adapted, air-cooled frequency converter on the pump motor enables an infinitely variable control mode between 26 Hz and a maximum of 65 Hz for all pumps of these series; all pump components in contact with fluid are made of 1.4301 stainless steel
  • Fittings: Each pump is fitted on the pressure side with a DVGW-tested, Ni-coated, CuZn gear-operated shut-off ball fitting and a DVGW-approved POM non-return valve in a CuZu housing
  • Diaphragm pressure vessel: 8 l/PN 16 located on the discharge side with a butyl rubber diaphragm, completely safe in accordance with food safety laws; complete with Ni-coated CuZn shut-off ball cock for tests and inspections, with drain and throughflow fitting in accordance with DIN 4807
