Designed for applications having high humidity or potentially explosive atmospheres.

Hudson, MA — Clark Solutions introduces the CU15 Series Miniature Air Operated Diaphragm Pumps. Ideal for pumping liquids with very high viscosity, including those containing suspended solids, CU Series Miniature Diaphragm Pumps are available in a range of component materials to facilitate optimum chemical compatibility. 

Available pump body materials include polypropylene (PP) with maximum temperature of 60°C (140°F), or ECTFE with a maximum temperature of 95°C (203°F).  The CU Mini Diaphragm Pumps are designed for applications with high humidity, and are also ATEX certified for potentially explosive atmospheres

CU Mini Diaphragm Pumps do not require lubricated air and feature a stall-prevention pneumatic system to assure safe running. These pumps have self-priming dry capacity of 3 meters (9.84 ft.), even with considerable suction head.  In addition, CU Series pumps offer fine tuning of speed without pressure loss and resist damage resulting from dry operation.
