Diaphragm Metering Pump
Capacity range of single pump: 0.19 – 60 l/h, 10 – 1.5 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 EC EX Regulation 94/9/EC (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
