Johnson Pump CM30P7-1 - 12V - Circulation Pump - 10-24488-03
The Johnson Pump CM30P7-1 – 12V Circulation Pump (10-24488-03) is a compact, high-efficiency centrifugal circulation pump engineered for continuous duty freshwater and water/glycol circulation in marine, RV, automotive, and industrial applications. Featuring a magnetic drive design, this pump delivers dependable fluid movement with minimal current draw, making it ideal for propulsion cooling, freshwater loop circulation, HVAC systems, live well and fish tank circulation, and other systems where low-noise, reliable flow is needed.
Constructed with corrosion-resistant thermoplastic materials and a stainless steel shaft, the CM30P7-1 offers long-lasting durability in demanding environments. The magnetic drive eliminates traditional shaft seals for a leak-resistant design, while the enclosed permanent-magnet motor is designed for continuous operation.
This 12-volt DC circulation pump is optimized for systems that do not require self-priming. Its lightweight design, along with flexible mounting options, makes it easy to install and service.
Key Features & Performance
-
Sealless Magnetic Drive: This design eliminates the need for a traditional shaft seal, significantly reducing the risk of leaks and extending the pump's operational life.
-
High Efficiency: Delivers a maximum flow rate of 5.3 GPM (20 L/min) with very low electrical current consumption, drawing a maximum of only 27 Watts.
-
All-Weather Reliability: The motor is IP67 rated, making it both dust-proof and waterproof. It can even withstand temporary submersion for up to 30 minutes.
-
Fluid Compatibility: Highly versatile and suitable for use with fresh water, salt water, and ethylene glycol mixtures (up to 60% glycol).
-
Dry-Run Capability: While it is a normal-priming centrifugal pump that should ideally be flooded, it is engineered to withstand dry running for up to 30 minutes without immediate damage.

Installation Insight
Since this is a centrifugal pump, it is not self-priming. It must be mounted in a location where it will be flooded with liquid (below the header tank or fluid level) to ensure the impeller is always submerged before the motor starts.
Typical Uses
-
Freshwater circulation loops on boats, RVs, and vehicles
-
Engine cooling circulation systems
-
HVAC cooling and heating loops
-
Live fish tank and aquaculture circulation
-
Water-to-water heat exchange systems
