Setup and Installation
Proper installation is crucial for the performance and longevity of your washdown pump kit. Follow these general guidelines:
- Mounting: Secure the pump using its industry-standard mounting pattern in a dry, well-ventilated area. Ensure the motor housing is protected from direct water exposure.
- Water Inlet: Connect the water source to the pump's inlet. Always install the provided 50 mesh strainer on the inlet side to prevent debris from entering the pump.
- Water Outlet: Connect the washdown hose to the pump's outlet using the provided fittings. Attach the sprayer nozzle to the other end of the hose.
- Electrical Connections: Connect the pump to a 12V DC power source. Ensure the wire gauge (14 AWG recommended) and fuse (25 Amps recommended) are appropriate for the pump's current draw. Observe correct polarity. The pump has a lead length of 1.5m.
- Priming: The pump is self-priming up to 2 meters (6 feet). Ensure the inlet hose is filled with water before initial operation to aid in faster priming.

Operating Instructions
The Seaflo 51-Series pump is designed for automatic operation controlled by a pressure switch. It is suitable for both freshwater and saltwater applications.
- Power On: Once installed and connected, apply 12V DC power to the pump. The pump will briefly run to build pressure.
- Automatic Operation: The pump will automatically start when the pressure drops (e.g., when you open the sprayer nozzle) and stop when the pressure reaches 70 PSI (e.g., when you close the nozzle).
- Run Dry Capability: The pump is capable of running dry for normal workloads without damage. However, prolonged dry running should be avoided.
- Applications: This pump is ideal for cleaning boats, fish boxes, anchor wells, inflatable boats, and other similar washdown tasks. The spray gun has a range of up to 10 meters (32.81 feet).
Caution: This pump is not designed for use with thick liquids such as oil or fructose. Use only with water.
Maintenance
Regular maintenance will ensure the longevity and optimal performance of your pump kit.
- Strainer Cleaning: Periodically inspect and clean the 50 mesh strainer to ensure unrestricted water flow and prevent debris from entering the pump.
- Connections: Check all hose and electrical connections regularly for tightness and signs of wear or corrosion.
- Winterization: In freezing conditions, ensure the pump and hoses are drained to prevent damage from ice expansion.
- Motor Protection: The motor is covered with an anti-corrosion varnish. Keep the motor housing clean and dry.
Troubleshooting
If you encounter issues with your pump, refer to the following common problems and solutions:
| Problem | Possible Cause / Solution |
|---|---|
| Pump does not turn on. | Check power supply, fuse, and electrical connections. Ensure correct polarity. |
| Low flow or pressure. | Check for clogged strainer, kinks in the hose, or air in the system. Ensure adequate water supply. |
| Pump runs continuously or cycles rapidly. | Check for leaks in the system (hoses, fittings, nozzle). Ensure the nozzle is fully closed when not in use. |
| Water present in a new pump. | This is normal. Each pump undergoes quality control testing at the factory, which may leave residual water. |
| Pump motor overheats. | Ensure proper ventilation around the pump. Avoid prolonged continuous operation; this pump is designed for intermittent duty. |
