ProMinent - Model EXTRONIC -Diaphragm Metering Pump

Precise metering with explosion protection

The ATEX-compliant diaphragm metering pump EXTRONIC (EXBb) is tested and approved in line with EN 60079/-1 for the ignition type '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 drive, there is IP 65 protection against contact and moisture as per EN 60529 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 in mains voltage and automatically switches from 50 to 60 Hz operation
• Broad range of applications due to operating voltages of 230 V, 115 V, special voltage on request
• Ease of integration into processes, thanks to the range of control types (internal, external contact, analogue)
• Also suitable for use with gaseous media, thanks to the self-bleeding head

• Stroke length: 1.25 mm, rod force: 2000 N
• Stroke length adjustment range: 0 – 100% in operation and idle
• Stroke length adjustment: manually using scaled rotary dial
• Metering reproducibility is better than ± 2 % within the 30 – 100% stroke length range under defined conditions and with correct installation. Observe the information in the operating instructions
• DEVELOPAN® diaphragm with PTFE coating with diaphragm rupture monitoring
• Wetted materials: Polypropylene, PVC, PTFE with carbon, clear acrylic, stainless steel, special designs available on request
• Degree of protection: IP 65 (even with open front cover)
• Short stroke solenoid drive and complete pump control integrated in the pump housing
• 'Internal', 'External contact' and 'Analogue' control inputs are available, the latter two also available as intrinsically safe and approved to EN 60079-11
• EXBb G for use in areas with hazardous gases and vapours, degree of protection EEx [i,a] d IIC T6

This means:

• EEx - Equipment complies with European standards
• [i,a] - Control input is intrinsically safe when 2 independent errors occur
• d - Type of ignition protection, compression-resistant enclosure
• IIC - Explosion group II for all areas at risk from explosion with the exception of mining, sub-group IIC (includes IIA and IIB)
• T6 - Temperature class permissible for gases and vapours with ignition temperature > 85 °C
