- Automatic Operation: The pump features an automatic power switch that turns off the pump when no flow is needed, helping to conserve battery power and reduce wear. It will restart automatically when flow is required again.
- Continuous Duty: The pump has a 100% continuous duty rating, meaning it can operate without a cool-down period.
- Applications: This pump is suitable for various fluid transfer applications, including agricultural spraying (herbicides, insecticides), industrial uses, and commercial tasks.
Maintenance
Regular maintenance ensures the longevity and efficient operation of your pump.
- Flushing After Use: If using the pump for disinfectants, sanitizing agents, or other chemicals, it is crucial to flush the pump thoroughly with clean water after each use. This prevents chemical buildup and corrosion.
- Winterization: In freezing conditions, drain all fluids from the pump and lines to prevent damage from ice expansion.
- Inspection: Periodically inspect the pump for any signs of wear, leaks, or damage to hoses and connections. Ensure all fasteners are tight.
- Viton Valves and Santoprene Diaphragm: The pump is designed with corrosion-resistant Viton valves and a Santoprene diaphragm for long-term durability, minimizing the need for frequent component replacement.
Troubleshooting
If you encounter issues with your Everflo EF7000-BOX pump, refer to the following common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not run | No power, loose wiring, blown fuse, faulty switch. | Check power source, ensure connections are secure, inspect and replace fuse if necessary, test switch. |
| Low flow or no pressure | Clogged inlet filter, air leak in suction line, restricted discharge line, worn pump head. | Clean inlet filter, check all connections for air leaks, clear any obstructions in the discharge line, inspect pump head for damage. |
| Pump cycles on and off rapidly | Pressure switch issue, small leak in system, restricted flow. | Check for leaks in the system, ensure adequate flow, contact manufacturer if pressure switch is suspected to be faulty. |
| Leaking from pump head | Loose screws, damaged diaphragm or seals. | Tighten pump head screws. If leaking persists, internal components may be damaged and require professional service or replacement. |
