Control Systems
  • Smart Conveying Technology

    For a rapid replacement of the rotor and stator.

  • Compression Casing

    Ensures optimal feeding of the media.

  • Extension Hopper

    Connected to the upstream dewatering machine with integrated filling level sensor and pump speed.

  • Control intelligence

    Frequency inverter with integrated PLC.

  • Open hopper pump

    Excellent discharge in hopper.

  • Injector

    Connection for injection of compressed air.

  • Air receiver

    For storing and releasing compressed air from the upstream compressor.


  • For the sterilization of sewage sludge and the processing of dewatered sludge into fertilizers or for safe disposal into landfills.
  • Sterilizes and stabilizes sludge
  • Adjustable lime metering based on the amount of sludge and level of treatment needed
  • Optimum mixing of hydrated or quick lime due to direct control of sludge level at the paddle shaft of the SEEPEX hopper pump with dry running protection TSE and dynamic temperature control
  • For keeping filling levels and flow rates in pump hoppers or supply tanks constant
  • Integrated protection and control functions
  • Compact PLC with integrated display and control unit. Internal PID interface to control pump speed and set the fluid levels in the hopper or supply tank
  • Process evaluation sent as text messages
  • Filter press filling process, pressure based control of pre-filling pump and high pressure pump
  • Polymer pump quantity-based regulation
  • Polymer pump throughput control
  • Stator temperature control (dry running protection - TSE)
SAI Controller
  • For the control of sewage sludge conveyance over up to 1,000 meters (Smart Air Injection)
  • Control over the conveying capacity of the connected pumps
  • Control of compressed air injection for triggering dense phase pneumatic conveying 
  • Monitoring of security functionalities: Overpressure and dry running protection
  • Visualization and monitoring of the SAI process (e.g. compressed air and lubricant consumption)
  • Error diagnostics
  • Interface with the higher-level control System
