EXtronic® Diaphragm Metering Pump

EXtronic® Diaphragm Metering Pump

The series ProMinent EXtronic®, approved according the new EU EX Directive 94/9/EU (ATEX), for the metering of liquid media in gas-explosive operating sites and firedamp-endangered mining operations.

Designs

  • EXBb G Gas explosion protection device group II, device class 2G (zone 1, group II)
  • EXBb M Firedamp protection device group I, device class M2 (group I)

Advantages

  • ATEX-compliant
  • Exact adjustment and high level of reproducibility thanks to micrometer adjusting knob for stroke length
  • Reliable operation thanks to compensation even in case of supply voltage fluctuations. Switching from 50Hz to 60Hz operation is executed automatically.
  • Further range of application thanks to operating voltages of 500V, 230v, 115V
  • Easy integration into processes thanks to three different types of control
  • Also suitable for outgassing media thanks to self-venting liquid end
  • Comprehensive range of Ex-protected accessories and pump accessories

Application Areas

  • EXBg G for the use in areas at risk by gasses and vapours (degree of protection EEx [i, a] d IIC T6)
  • EXBb M for use in firedamp-endangered mining operations (degree of protection EEx d I/II C T6)

Explanation:

EEx: equipment conforms to European standards
[i,a]: control input intrinsically safe if two independent faults occur
d: Type of protection, flameproof enclosure
I C: Explosion group I for firedamp-endangered mining operations
II C:  Explosion group II for all other explosion-endangered areas, sub-group IIC (includes IIA and IIB)
T6:  Temperature class, permissible for gasses and vapours with ignition temperature > 85°C. This is the highest temperature class, it includes T 1 through T5.

Features

  • Output range of 0.19l/h to 60l/ at backpressures of up to max. 25bar.
  • Micrometer adjustment knob for stroke length
  • For outgassing media, self-venting liquid ends made of plexiglass (NS) and PVC (PS)
  • Delivery unit with the proven DEVELOPAN® metering diaphragm with Teflon coating
  • Liquid end materials: plexiglass, polypropylene (PP), PTFE Teflon®, stainless steel, material no. 1.4404, and SB for flammable media
  • Type 2501 SSM/SBM with diaphragm failure messaging, e.g. for the use in gas odorisation 
  • Control inputs “external contact”, “analogue” and “potential-free ON/OFF” are available as EXBb intrinsically safe – approved according to EN 50020.
  • Control type “internal”: Stroke length adjustment 1:10; stroke frequency adjustment 1:25, total adjustment range 1:250
  • Control type “external contact”: Stroke length adjustment 1:10; stroke frequency control 0 – 100 %, depending on the external switching contacts
  • Control type “analogue”: Stroke length adjustment 1:10; stroke frequency control 0 -100 %, proportional to the analogue signal 0/4-20mA
  • The short-stroke solenoid and the complete pump control are integrated in the pump housing. Protection against contact and moisture according to DIN 40050 is IP 65, also with opened front cover 
  • Tested and approved according to the harmonised EU regulations of EN 50014/50018 for the type of protection “flameproof enclosure”
  • Highest degree of protection of this type of protection. Apart from the EU countries, this approval is also recognised by many other international authorities
