4. Operation
4.1 Initial Start-up
- Ensure all electrical and hose connections are secure.
- Fill the supply tank with the desired fluid.
- Turn on the 12V DC power supply to the pump. The pump will begin to prime and build pressure.
- Once pressure is built, the pump's automatic shut-off feature will activate, stopping the motor until flow is required.
4.2 General Use
The Everflo EF1000-BOX pump features an automatic shut-off when no flow is required, which helps conserve battery life. When a spray wand or nozzle is opened, the pump will automatically restart to maintain pressure and flow. The pump is compatible with glyphosate and other agricultural brand herbicides due to its polypropylene housing, Viton valves, and Neoprene diaphragm.
4.3 Applications
This diaphragm pump is suitable for a variety of applications, including:
- Tree spraying
- Lawn and garden spraying
- Livestock spraying
- Fence line spraying
- General fluid transfer

5. Maintenance
5.1 Cleaning After Use
Proper cleaning after each use is crucial for extending the life of your pump, especially when using herbicides or pesticides. Failure to clean the pump can lead to chemical residue buildup, which may damage internal components and seals.
- Drain the Tank: Completely drain any remaining fluid from the supply tank.
- Rinse Tank: Add clean water to the tank and drain it again to remove initial residues.
- Flush System: Add approximately 2 inches of clean water to the tank. Power on the pump and spray the water out through the nozzle until the water hitting the ground appears clear and free of suds or chemical residue.
- Relieve Pressure: Turn off the pump and squeeze the lever on the wand to release any remaining pressure within the pump and lines.
- Storage: Store the unit in a clean, dry place. It is recommended to leave some clean water in the tank, but not in the pump itself, to prevent seals from drying out.
5.2 Component Care
The pump features a polypropylene housing and valve plate, Viton valves, and a Neoprene diaphragm for chemical resistance and durability. Regular inspection of these components for wear or damage is recommended. Zinc-plated steel fasteners resist corrosion.
6. Troubleshooting
This section addresses common issues you might encounter with your Everflo EF1000-BOX pump.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not turn on | No power, blown fuse, faulty switch, loose electrical connection. | Check 12V power supply. Inspect and replace inline fuse if blown. Verify switch functionality. Tighten electrical connections. |
| Pump runs but no fluid or low flow | Clogged inlet filter, air leak in suction line, kinked hose, low fluid level, worn diaphragm/valves. | Clean inlet filter. Check all suction line connections for air leaks. Straighten hoses. Refill tank. Inspect and replace diaphragm/valves if necessary. |
| Pump runs continuously (does not shut off) | Leak in system, faulty pressure switch, air in system. | Check all hoses, fittings, and spray components for leaks. Inspect pressure switch for damage. Bleed air from the system by running the pump with an open nozzle. |
| Pump leaks from head | Loose head screws, damaged O-rings or seals, cracked housing. | Ensure head screws are tightened evenly. Inspect and replace O-rings or seals. If housing is cracked, pump replacement may be necessary. |
| Reduced pressure | Worn diaphragm/valves, partial clog, weak power supply. | Inspect and replace diaphragm/valves. Clear any clogs in the system. Ensure adequate 12V power supply. |
