Description/construction

  • Baseplate:Hydraulically and electrically pre-configured pump system, run-down tank, control, pneumatic valves, structure-borne noise insulation, measuring instruments, emergency spillway
  • Pipework:Complete pipework made of stainless steel, suitable for the connection of all conventional piping materials; the pipework is designed according to the overall hydraulic performance of the pressure boosting system
  • Pumps:Helix V, VE or MVI, MVIE series pumps, for more information about the pump, please refer to the catalogue section “High-pressure multistage centrifugal pumps”
  • Monitoring connection:Control connection for the function test of pumps and actuators.
  • Stagnant water connection: Integrated stagnant water connection for replacing the volume of water of the drinking water connection pipe in accordance with DIN 1988-600.Flushing quantity depending on the time, conductor length/content.
  • Pump control: Manual/Automatic switch per pump, standard soft starter for individual switching capacity over 4 kW.Requirements-dependent and pressure-dependent cut-in and deactivation of the integrated pump(s).
  • Rotation connection ensuring consistent operating hour figures of all pumps of the drinking water-sewage system.
  • Emergency operation pipe:Securing of the pump minimum volume flow in accordance with DIN 14462 and DIN EN 12845
  • Operating and error messages:Functional check of the drinking water-replenishment valves and pumps, overflow indicator, dry-running protection, operating and error messages in plain text display
  • Building management systems: Potential-free contact for external fault display
  • Run-down tank: Specially developed run-down tanks made of stainless steel with free outlet in accordance with DIN EN 1717. Replenishment of high volume flows at low volume of water in the run-down tank. In the separator integrated with tank for reduction of gas input and reduction of the inflow speed.Connection for possible connection of the pump test pipe to the run-down tank.
  • Drinking water replenishment:Replenishment from public mains in accordance with DIN EN 1717 with free outlet type AB
  • Emergency drainage with overflow siphon:Upon cut in of the emergency spillway with integrated anti-syphon trap, drainage is performed in the underpressure system
