Clark Solutions has introduced two miniature air operated diaphragm pumps: the MID and the CU15, both ATEX certified for potentially explosive atmospheres.

These air driven diaphragm pumps are a good choice for environmental/process emission monitoring within the petrochemical industries and other process industries. MID and CU15 Pumps also feature a stall-prevention pneumatic system design which does not require lubricated air and therefore allows “dry” operation without incurring damage. Self-priming dry capacity is 3 meters, even with considerable suction head, and pump speed can be fine-tuned without pressure loss for unrivalled versatility. The standard version of both pumps is ATEX classified II 3/3 GD c IIB T135°C (for zone 2), and the optional Conduct versions are ATEX classified II 2/2 GD c IIB T135°C (for zone 1).

Model MID Air-Operated Miniature Diaphragm Pumps provide flow rates to 5 LPM (1.32 GPM) at pressures to 70 Meters (99.7 PSI), and have a maximum operating temperature of 60°C (140°F).

CU15 Air-Operated Miniature Diaphragm Pumps provide flow rates to 17 LPM (4.49 GPM) at pressures to 70 Meters (99.7 PSI). Maximum operating temperature for polypropylene models is 60°C (140°F); for ECTFE models it is 95°C (203°F).
