4. Setup and Installation
Proper installation is crucial for the pump's performance and longevity. The pump can be mounted in any position.
4.1 Unpacking and Inspection
Carefully remove the pump from its packaging. Inspect for any visible damage that may have occurred during shipping. Report any damage to your supplier immediately.
4.2 Mounting
Mount the pump in a dry, well-ventilated area. Ensure the mounting surface is stable and secure. The pump includes a metal base plate with rubber feet for vibration dampening. Secure the pump using appropriate fasteners through the mounting holes on the base.
4.3 Plumbing Connections
Connect 1/2" - 14 Male Parallel Thread fittings to the pump's inlet and outlet ports. Ensure all connections are tight to prevent leaks. Avoid overtightening. It is recommended to use flexible hoses to minimize vibration and noise transmission.
4.4 Electrical Connections
The pump operates on 115 Volts AC. Connect the pump to a suitable power source according to local electrical codes. The pump is supplied with ground wires. Ensure proper grounding for safety. If you are unsure about electrical connections, consult a qualified electrician.

5. Operating Instructions
Once properly installed, the SHURflo 2088-594-154 pump is designed for straightforward operation.
5.1 Priming the Pump
The pump is self-priming up to 9 vertical feet. To prime, ensure the inlet line is submerged in the fluid source and the outlet line is open to allow air to escape. Turn on the power. The pump will draw fluid and expel air until a steady flow is achieved.
5.2 Automatic Operation
The integrated 45 psi demand switch automatically turns the pump on when system pressure drops (e.g., when a faucet is opened) and off when the pressure rises (e.g., when a faucet is closed). This allows for on-demand operation without manual intervention.
5.3 Dry Running
The pump is designed to run dry without damage. However, continuous dry running is not recommended as it can lead to unnecessary wear and tear. Ensure a consistent fluid supply.
6. Maintenance
The SHURflo 2088-594-154 pump is designed for easy maintenance. Regular checks can extend its lifespan.
- Periodic Inspection: Regularly check all plumbing and electrical connections for tightness and signs of wear.
- Cleanliness: Keep the pump exterior clean and free from debris.
- Winterization (if applicable): If the pump is used in an environment where freezing temperatures may occur, ensure it is drained and protected from freezing to prevent damage.
- Diaphragm and Valve Checks: While designed for durability, if flow or pressure issues persist, the diaphragm and valves may require inspection or replacement. Consult a qualified technician or SHURFLO service center.
7. Troubleshooting
This section provides solutions to common issues you might encounter.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not turn on | No power; Blown fuse/circuit breaker; Loose wiring; Faulty pressure switch | Check power supply; Reset breaker/replace fuse; Inspect and secure wiring; Test/replace pressure switch |
| Low flow or pressure | Clogged inlet filter; Air leak in inlet line; Restricted outlet; Worn diaphragm/valves; Low voltage | Clean filter; Check inlet connections for leaks; Clear any obstructions; Inspect/replace diaphragm/valves; Verify correct voltage supply |
| Pump cycles on and off rapidly | Small leak in system; Restricted outlet; Accumulator tank issues (if present) | Check for leaks in plumbing; Ensure outlet is not restricted; Inspect accumulator tank for proper charge/function |
| Excessive noise/vibration | Loose mounting; Air in system; Pump cavitating; Worn motor bearings | Tighten mounting screws; Bleed air from system; Ensure adequate fluid supply; Contact service for motor issues |
