March AC-5M-MD Magnetic Drive Pump

March Pump's AC-5M-MD is an American seal-less centrifugal magnetic drive pump ideal for marine applications. It is capable of generating a maximum flow of 17 gal per minute at 1' and its maximum head is 27' (11 PSI). The pump is ignition protected per SAE J1171 and ISO 8846, and has extended run dry protection through the use of a carbon bushing. It is capable of 48,000 BTU an hour.

March C and CP series magnetic-drive pumps have long been trusted for marine seawater circulation thanks to their reliable seal-less centrifugal design. New M-series pumps were designed with marine specific improvements including enhanced corrosion protection, extended run-dry protection, and standardized configurations for continuous sea water and fresh water circulation systems.

Notes:

• This pump is not self-priming, a non-self-priming pump cannot remove air from its suction line by itself and must already be filled with liquid before it can move fluid:
  • Starting the pump dry may cause it to overheat, cause damage to seals or internal components, and will not move water
• It is recommended to use a water strainer with this pump (not included)
