Product Description
March Marine Pumps
March marine pumps are engineered to support reliable performance across critical applications, including marine AC water pump systems, boat AC pump systems, and marine engine cooling pump systems.
Without proper flow, temperatures rise, systems strain, and equipment failure becomes a real risk.
Seal-Less Magnetic Drive Design
One of the biggest advantages of March marine pumps is their magnetic drive (seal-less) design.
Unlike traditional pumps, there are no mechanical seals to wear out or fail.
Why this matters:
✔ Reduces leak risk
✔ Minimizes maintenance requirements
✔ Improves long-term reliability
✔ Ideal for continuous-duty marine environments
For marine systems, where exposure to water and moisture is constant, this design significantly improves operational dependability.
Marine Pump Configurations Available
March offers a range of magnetic drive marine pump configurations to match different vessel requirements:
Above-Water Marine Pumps
Installed outside the fluid, commonly used in marine engine cooling pump systems.
Explore AC-5M-MD (AC-5C-MD )
DC Marine Pumps (12V & 24V)
Ideal for battery-powered systems and smaller marine applications requiring compact, efficient circulation.
These pumps are commonly used as 12 volt water pumps, 24 volt water pumps, and boat DC pump systems.

Submersible Marine Pumps (LC Series - Marine "M" Versions)
Many March marine pumps are now available in the updated Marine “M” Series, designed specifically for seawater applications.
Most Marine ‘M’ Series pumps Include (excluding LC-2M-MD):
✔ 3-flat stainless steel shaft
✔ Carbon bushing design
What this improves:
- Reduced wear in continuous operation
- Better resistance to temporary dry running
- Increased reliability in marine environments
While no pump is immune to dry running damage, these enhancements provide operators more time to restore flow before damage occurs.
