Key Performance Features
-
Leak-Proof Magnetic Drive: The motor and pump are magnetically coupled, eliminating the need for a traditional shaft seal. This seal-less design prevents leaks and significantly extends the service life of the unit.
-
Low Power Consumption: Operates on a 12V DC system with a maximum draw of only 14 Watts, making it ideal for solar-powered or battery-dependent systems where energy conservation is critical.
-
Continuous Duty Performance: Features a permanent magnet, ball-bearing motor rated for up to 5,000 hours of uninterrupted service, ensuring reliable operation for livewells or refrigeration cooling.
-
Versatile Fluid Compatibility: Safely handles fresh water, salt water, and ethylene glycol mixtures (up to 60%). It is built to operate in extreme temperatures ranging from -40°F to 212°F.
-
Engine Room Safe: The unit is ISO 8846 ignition protected, allowing for safe installation in engine compartments and other potentially hazardous areas on your vessel.
-
Magnetic Drive Technology: The motor and pump are magnetically coupled, creating a leak-proof design that eliminates the need for a traditional shaft seal. This significantly reduces maintenance and prevents leaks.
-
Continuous Duty Motor: Equipped with a permanent magnet, ball-bearing motor rated for up to 5,000 hours of uninterrupted service. It is built to handle voltage fluctuations of ±20%.
-
High Efficiency: Provides a steady flow rate of 4.0 GPM (15 L/min) while maintaining very low electrical consumption (Max 14W), making it ideal for battery-powered systems.
-
Liquid Versatility: Safe for use with fresh water, salt water, and ethylene glycol mixtures (up to 60% glycol). It can handle extreme liquid temperatures ranging from -40°F to 212°F.
-
Safety & Durability: The unit is ISO 8846 ignition protected, meaning it can be safely installed in engine compartments. It is also designed to withstand dry running for up to 30 minutes without damage.

Installation & Maintenance
This is a normal-priming centrifugal pump, which means it is not self-priming. It must be mounted in a position where it is always flooded (below the water level of the source) or be manually primed before use. This model includes a flexible cord for easier wiring integration.
Pro Tip: While the pump can handle some dry running, its lifespan is maximized when kept flooded. It should not be used with soiled water containing hard particles, as these can damage the magnetic drive.
Comparison: CM10 vs. CM30
If you need more power, the CM30P7-1 is the larger sibling to this pump, offering a higher flow rate of approximately 5.3 GPM to 6.9 GPM depending on the port size.
