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.
