Description/structure

  • Support frame: galvanised, with height-adjustable anti-vibration mounts, providing good structure-borne sound insulation; other versions on request
  • Pipe system: complete piping system in stainless steel 1.4301, suitable for connection of all common pipe materials; the pipe system is designed according to the overall hydraulic capacity of the FLA pressure booster system
  • Pumps: pumps of the series Helix FIRST V 16, 22, 36, 52 and MVI 70; all pump components in contact with fluid are made of stainless steel / EN-GJL-250 with cataphoresis coating. See catalog section "High-pressure centrifugal pumps" for more information about the pump.
  • Fittings: Each pump has a 1.4571 stainless steel throttle needle valve on the check valve to return the volumetric flow through the bypass to the receiving tank. All throttle valves and shut-off valves are sealed and secured against unintended adjustment. The pumps are equipped with automatic venting valves on the top side of the hydraulic section.
  • Diaphragm pressure vessel 8 l/PN 16, mounted on the end pressure side. For inspection and testing purposes, equipped with a special flow valve which allows the diaphragm pressure tank to be shut off and emptied
  • Pressure switch: pressure switch is positioned on the discharge side, for activation of the central FLA controller
  • Pressure display: Pressure gauge (ø 63 mm) on the discharge side; additional digital indication of operating pressure and FLA controller settings
  • Control unit/controller: The unit is equipped with a special FLA controller as standard
