Why MarinAire?
MarinAire sets the standard in the marine air conditioning industry with cutting-edge patented technology. Click here to learn more about our company.
MarinAire magnetic drive marine air conditioning pumps are engineered for reliable, long-term performance in demanding marine environments. Designed specifically for marine HVAC applications, these pumps deliver efficient and quiet water circulation while eliminating common failure points found in traditional mechanical seal pumps.
The MarinAire MFP Series utilizes a seal-less magnetic drive design, creating a completely leak-proof pumping system with no shaft seals to wear, corrode, or fail over time. This makes them an ideal solution for circulating water in marine air conditioning systems, where reliability and safety are critical.
All MarinAire marine pumps are ignition protected, making them suitable for installation in engine rooms and other enclosed marine spaces. They are non-submersible, in-line pumps, intended for dry-mount installation above the bilge, ensuring compliance with marine safety standards while simplifying service access.
Built to handle fresh water, and salt water, the MFP Series features advanced ceramic bearings formulated for exceptional resistance to abrasion and corrosion. This design significantly extends pump life, even in harsh saltwater environments.
In addition to durability, MarinAire pumps are optimized for efficiency. They offer low power consumption, low starting current, and high energy efficiency, helping reduce electrical load on onboard systems without sacrificing performance. Their quiet operation and smooth flow characteristics make them ideal for continuous-duty marine air conditioning circulation.
With a compact footprint, modern design, and marine-specific engineering, MarinAire magnetic drive pumps provide a dependable, long-lasting solution for boat owners, installers, and OEMs seeking high-performance marine air conditioning pump systems.

The information below applies only to MSWA brand marine air conditioning units and may not apply to other brands or systems.
For standard installations, each MSWA air conditioning unit requires its own circulation pump. Pump sizing depends on your MSWA unit capacity, installation layout, and plumbing run. Based on what most MSWA customers typically use, the following circulation pump sizes are common:
We carry two types of circulation pumps, and the correct choice also depends on where and how the pump is installed:
Each pump has different head pressure ratings, and factors such as hose length, vertical lift, fittings, and bends all affect flow.
Some installations use a single circulation pump to supply multiple MSWA units. In these cases, the pump must be sized by combining the required flow for each unit, and a pump relay panel is required to ensure proper operation.
Example:
Two MSWA 16K units (500 GPH each) would typically require a 1,000 GPH circulation pump and a compatible pump relay panel.
Proper sizing is critical:
Because shared-pump systems are more dependent on plumbing layout and head pressure, we strongly recommend consulting a qualified marine air conditioning installer to confirm pump sizing and system design.
The main difference is how and where they are installed.
Most March pumps are submersible, meaning they are designed to be installed in the bilge or areas that have high moisture. (note** the TE-5M-MD 1000GPH pump is not submersible)
MarinAire pumps are non-submersible and designed for dry, above-bilge installations such as closets.
Both March and MarinAire pumps are ignition protected and magnetic drive and suitable for marine environments. The correct choice depends on your installation layout, available space, plumbing run, and head pressure requirements.
If you’re unsure which pump is best for your setup, checking the spec sheets of the pumps are recommended.
No. These circulation pumps are designed and intended specifically for marine air conditioning and marine water circulation systems.
