3. Configuración e instalación

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 Colocación

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 Conexión de alimentación

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. Instrucións de funcionamento

The Tsurumi 50UT2.75S pump is designed for automatic operation, making it user-friendly for continuous or intermittent pumping tasks.

4.1 Funcionamento automático

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 Funcionamento manual (se corresponde)

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. Mantemento

Regular maintenance ensures the longevity and reliable performance of your Tsurumi 50UT2.75S pump. Always disconnect power before performing any maintenance.

5.1 Inspección xeral

• 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 Limpeza

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 Almacenamento

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.
