Product Uses

Here’s a polished and professional version of your text with improved formatting and clarity:

Suitable for clean water and liquids that are not chemically aggressive to the pump's construction materials.

EN733 centrifugal pumps are ideal for:

Water supply systems

Cleaning systems

Pressure boosting

Firefighting systems

Irrigation

Industrial applications

HVAC water circulation

Agricultural uses

Installation

1. The pump must be installed in a dry, cool, well-ventilated area where the ambient temperature does not drop below 0°C (frost-free). The diameter of the inlet pipe must not be smaller than that of the outlet pipe.

2. Before connecting the pump to the pipeline, verify the flow direction using the arrow marked on the pump casing. To ensure a sealed connection, install a rubber gasket or other sealing material between the flanges.

3. The installation site must provide sufficient space to ensure proper airflow and allow for future maintenance, disassembly, and servicing of the pump.

4. Isolation valves should be installed at the pump’s inlet and outlet to prevent system drainage during maintenance.

5. When installing the pipeline, ensure that the pump is not subjected to any pulling force from the piping.

6. The actual operating requirements of the pump must be fully considered, including its suction performance and pipeline pressure. Therefore, the inlet and discharge pipe diameters must be properly designed before installation.

7. The pump must not be installed at the lowest point of the system to avoid sediment accumulation.

8. During pipeline installation, avoid cavitation, particularly at the pump’s inlet side.
