3. Setup and Installation
Proper setup is crucial for the optimal performance and longevity of your Tsurumi 50UT2.75S pump. Ensure all safety precautions are followed before beginning installation.
3.1 Placement
The pump is designed for submersible use. Place the pump on a solid, level surface in the liquid to be pumped. Ensure it is not resting directly on soft sediment or debris that could impede its operation or clog the intake.
3.2 Discharge Connection
Connect a standard 2-inch hose or pipe to the pump's discharge port. Secure the connection to prevent leaks and ensure efficient flow. For permanent installations, consider using a check valve to prevent backflow.
3.3 Power Connection
The pump operates on 115V power. Connect the 32-foot power cord to a grounded electrical outlet. Ensure the power supply matches the pump's voltage requirements. Avoid using extension cords if possible; if necessary, use a heavy-duty, outdoor-rated extension cord of appropriate gauge.
4. Operating Instructions
The Tsurumi 50UT2.75S pump is designed for automatic operation, making it user-friendly for continuous or intermittent pumping tasks.
4.1 Automatic Operation
The integrated ball float switch controls the pump's operation. When the water level rises to a predetermined point, the float activates the pump, initiating the pumping cycle. The pump will continue to operate until the water level drops, causing the float to deactivate the pump.
4.2 Manual Operation (if applicable)
Refer to the specific wiring diagram or control panel instructions if manual override or continuous operation is desired for specific applications. Always ensure the pump is fully submerged during operation to prevent dry running and potential damage.

5. Maintenance
Regular maintenance ensures the longevity and reliable performance of your Tsurumi 50UT2.75S pump. Always disconnect power before performing any maintenance.
5.1 General Inspection
- Periodically inspect the pump for any visible damage to the casing, power cord, or discharge port.
- Check for any signs of excessive wear or corrosion, especially on the resin impeller.
- Ensure the dual inner mechanical seal is intact and not leaking.
5.2 Cleaning
Remove any accumulated debris or foreign objects from the pump's intake screen and around the impeller. This prevents blockages and maintains optimal flow. The pump's design allows for handling solids, but excessive buildup can reduce efficiency.
5.3 Storage
If storing the pump for an extended period, clean it thoroughly and store it in a dry, protected area to prevent damage from freezing temperatures or environmental exposure.
6. Troubleshooting
This section provides guidance for common issues you might encounter with your Tsurumi 50UT2.75S pump. For complex problems, contact Tsurumi (America), Inc. support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start or run. | No power supply; Float switch stuck or obstructed; Thermal overload activated. | Check power connection and circuit breaker; Clear any obstructions around the float switch; Allow pump to cool down if thermal protection activated. |
| Pump runs but no water is discharged or flow is low. | Discharge hose/pipe clogged or kinked; Intake screen blocked; Impeller obstructed. | Inspect and clear discharge line; Clean intake screen; Inspect and clear impeller (disconnect power first). |
| Pump cycles on and off frequently. | Float switch range too narrow; Water level fluctuating rapidly. | Adjust float switch position if possible; Ensure proper sump/pit size for application. |
| Unusual noise or vibration. | Debris in pump; Worn bearings; Improper installation. | Disconnect power and check for debris; Contact service for internal component issues; Re-check installation for stability. |
