4. Setup and Installation
- Mounting: The pump can be mounted in any position. Secure it to a stable surface using appropriate fasteners through the mounting holes on the base. Ensure there is adequate space around the pump for ventilation and maintenance.
- Plumbing Connections: Connect your fluid lines to the 1/2" - 14 Male Parallel Thread Ports. Use thread sealant appropriate for your application to ensure leak-free connections. The pump is self-priming up to 9 vertical feet, but it is recommended to place the pump as close to the fluid source as possible.
- Electrical Connection: Connect the pump to a 115VAC power source. Ensure the power supply matches the pump's voltage requirements. It is recommended to use a 1.6 AMP slow blow fuse for protection.
- System Check: Before initial operation, verify all connections are secure and there are no obstructions in the fluid path.
5. Operation
The SHURFLO 2088-594-144 is an automatic demand pump. It will turn on when there is a demand for fluid (e.g., opening a spray nozzle) and turn off when the demand ceases or the system pressure reaches 45 psi.
- Initial Start-up: Once installed, open any discharge valves to allow air to escape the system. Apply power to the pump. The pump will begin to prime and move fluid. Close discharge valves once fluid flows steadily.
- Automatic Operation: The pump's internal demand switch will automatically regulate operation based on system pressure.
- Flow Rate: The pump delivers a maximum flow rate of 3.0 Gallons Per Minute (GPM).
6. Maintenance
This pump is designed for easy maintenance. Regular inspection and cleaning will ensure optimal performance and longevity.
- Filter Usage: It is highly recommended to install an inline filter on the intake side of the pump to prevent debris from entering and damaging the diaphragm or valves. Regularly inspect and clean this filter.
- Connection Checks: Periodically inspect all plumbing and electrical connections for leaks or corrosion. Tighten as necessary.
- Winterization: If the pump is exposed to freezing temperatures, ensure it is drained of all fluids to prevent damage.
- Diaphragm and Valve Inspection: If performance degrades, inspect the diaphragm and valves for wear or damage. Replacement kits are typically available from SHURFLO.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not turn on. | No power, blown fuse, faulty switch. | Check power supply, replace fuse (1.6 AMP slow blow), inspect wiring. |
| Low flow or no flow. | Clogged filter, air leak in intake, restricted line, worn diaphragm/valves. | Clean intake filter, check all intake connections for leaks, inspect lines for kinks, check diaphragm and valves. |
| Pump runs continuously or cycles rapidly. | Leak in discharge line, faulty pressure switch, air in system. | Check for leaks in the discharge plumbing, ensure all air is purged from the system, contact support if pressure switch is suspected. |
| Fluid leaking from pump head. | Loose connections, damaged seals or diaphragm. | Tighten port connections, inspect and replace seals or diaphragm if damaged. |
| Excessive noise or vibration. | Loose mounting, air in system, foreign object in pump. | Ensure pump is securely mounted, purge air from system, inspect pump for obstructions. |
