Bild vergrößerndelta® Membrandosierpumpe

Solenoid diaphragm metering pump with optoDrive® drive technology. Complete control of the suction and pressure stroke for an optimal adaptation to the metering task and monitoring of the peripheral hydraulic instruments via optoGuard®.

  • Capacity range 7.5 - 75 l/h, 25 - 2 bar
  • Continuous or pulsating dosing
  • Programmable suction and delivery stroke duration
  • Pump can be adapted to the dosing media
  • Integrated injection control optoGuard® detects blocked dosing points, broken dosing lines and air or gas bubbles trapped in the dosing head
  • Stroke length continuously adjustable from 0 - 100 % (recommended range 30 - 100 %)
  • Acrylic glass, PVDF and stainless steel material versions
  • Patented coarse/fine ventilation
  • Detection and indication of diaphragm failure
  • Large backlit graphic display
  • External control options via potential-free contacts with optional increase/reduce speed pulse
  • Interfaces for PROFIBUS® or CANopen
  • Connection for 2-stage level switch
  • Optional concentration input for volume-proportional dosing
  • Flexible adaptation to the metering task ensuring optimal metering accuracy
  • The integrated injection control optoGuard® detects hydraulic failures which can then be messaged via the optional relays
  • High level of economy thanks to savings with regard to accessories such as e. g. pulsation dampeners, flow monitoring etc.
  • High metering accuracy even at varying backpressure
