Both the Model MID and CU15 miniature air-operated diaphragm pumps (AODPs) are ATEX certified for potentially explosive atmospheres, making them suitable for environmental and process-emissions monitoring. The standard version of both pumps is ATEX classified II for Zone 2, and the optional Conduct versions are ATEX classified II for Zone 1. The pumps facilitate transfer of liquids with very high viscosity, and are available with polypropylene (PP) or ethylene chlorotrifluoroethylene (ECTFE) pump bodies. The MID provides flowrates up to 5 L/min at pressures of up to 99.7 psi, and has a maximum operating temperature of 60°C. The CU15 provides flowrates to 17 L/min, with maximum operating temperatures of 60°C for PP models and 95°C for ECTFE models. — Clark Solutions, Hudson, Mass.
