- Diaphragm Metering Pump

From

Capacity range of single head pump: 1 – 60 l/h; 25 – 1 bar. The diaphragm metering pump EXtronic is perfectly suited for the sensitive use of liquid media in facilities with an explosive gas atmosphere as well as for mines at risk of firedamp, as it is approved in compliance with the EU EX Regulation 2014/34/EU (ATEX).

Precise metering with explosion protection

The ATEX-compliant diaphragm metering pump Extronic (EXBb) is tested and approved in line with the harmonised EC provisions of EN 50014/50018 for 'compression-resistant enclosures' and thus offers the maximum level of protection. The short-stroke solenoid and the complete pump control are integrated in the pump housing so that, together with the explosion-proof power end, there is IP 65 protection against contact and humidity as per DIN 40050 even when the front cover is open.

Optimum adaptation for use in areas at risk from explosion

  • ATEX-compliant in line with EExd IIC T6 and EExd I/IIC T6
  • Excellent operating and functional reliability by a microprocessor controller, which compensates for fluctuations of mains voltage and automatically switches from 50 to 60 Hz operation
  • Broad range of applications with an operating voltage of 500 V, 230 V and 115 V
  • Ease of integration into processes thanks to the range of control types (internal, external contact, analogue)
  • Also suitable for gaseous media, thanks to self-bleeding head

Field of application

  • Oil, gas and petrochemicals
  • Mining
  • For use in areas at risk of gases and vapours
  • Use in mines at risk from firedamp
