1. Product Overview
The SEAFLO Magnetic Circulation Pump is a centrifugal magnetic drive pump designed for continuous duty in various applications, including marine air conditioning systems. It eliminates the need for a shaft seal, enhancing durability and reducing maintenance. The pump is serviceable with a standard screwdriver and can operate fully submerged or in open air, offering complete moisture protection. It is capable of pumping liquids with a specific gravity greater than water and higher viscosity.
Key Features:
- Suitable for AC systems up to 12,000 BTU.
- Run dry safe for normal workloads.
- Lifetime exceeding 10,000 hours.
- Continuous duty operation.
- 8.5 GPM seawater circulation pump.
- Designed to replace various marine air conditioning pump brands.

2.2 Typical Marine AC System Integration
The pump is commonly used in marine air conditioning systems to circulate seawater for cooling. A typical setup involves drawing water from a sea cock through a strainer, then pumping it through the A/C condenser coil, and finally discharging it via a sea water outlet.

3. Operating Instructions
The SEAFLO pump is designed for continuous operation and is safe to run dry under normal workloads. It can be installed either fully submerged or in an open-air environment, thanks to its moisture-protected design. Ensure the liquid temperature does not exceed 54°C (130°F) for optimal performance and longevity.
4. Maintenance
Regular maintenance ensures the longevity and efficient operation of your SEAFLO pump. The pump is designed to be serviceable with a standard screwdriver.
4.1 General Maintenance Tips
- Periodically inspect the pump's inlet and outlet for any blockages or debris.
- Ensure all electrical connections are clean and secure.
- Check for any signs of wear or damage to the power cord and housing.
- If the pump is operating in an open-air environment, ensure it is protected from excessive moisture and direct sunlight.

5. Troubleshooting
If you encounter issues with your SEAFLO pump, consider the following common troubleshooting steps:
- No Power: Check electrical connections, ensure the power source is active, and verify the correct voltage (115V or 230V) is supplied to the pump.
- Low Flow or No Flow: Inspect the inlet and outlet for blockages. Clean any strainers in the system. Check for air leaks in the suction line. Ensure the impeller system (Key 6) is free from debris and operating correctly.
- Unusual Noise: This could indicate debris in the pump chamber, a worn bearing, or an issue with the impeller. Disassemble the pump (refer to Section 4.2) and inspect components.
- Overheating: Ensure adequate liquid flow through the pump. Verify the liquid temperature is within the specified limits (max 54°C / 130°F).
If problems persist after these steps, contact SEAFLO customer support or a qualified technician.
