The March AC-1A-MD-1/2 is a compact, open-air (non-submersible) magnetic drive pump with 1/2-inch barb inlet and outlet ports, delivering up to 3 GPM at heads to 5 feet (2 PSI) on a 1/200 HP, 115V single-phase motor. Nylon and polypropylene wetted parts with an exposed ceramic magnet and 316 stainless steel shaft handle fluid temperatures to 190°F. Applications include chemical transfer, photographic processing equipment, small refrigeration systems, and decorative water displays. Since the pump is magnetically coupled rather than shaft-sealed, it runs leak-free with virtually no maintenance. A 3/8-inch port version (AC-1A-MD-3/8) is also available for applications needing a smaller connection or slightly lower flow
