How to Install Vertical Inline Circulation Pump Properly?

The proper installation and precautions for vertical inline circulation pumps are crucial for their efficient and stable operation. During installation, it is essential to ensure that the pump body is level, connections are secure, and valves are properly positioned. It is also crucial to avoid performance degradation caused by cavitation. In addition, regular inspection and maintenance of the pump and pipeline system, including cleaning filters, checking sealing elements, and lubricating bearings, can effectively extend the equipment's lifespan, prevent leakage and system failures, and ensure the reliable and efficient operation of the entire pipeline system. These measures not only improve the pump's working efficiency but also significantly reduce downtime and maintenance costs.

Installation Requirements

• If the system pipeline can support the pumps, pumps with 2.2kW motor power (including 2.2kW) can be hung inline; if the system pipeline cannot support the pumps or the pump motor power is higher than 2.2kW, the pump must be installed in brackets or base.
• Pumps with motor power lower than 2.2kW (including 2.2kW) can be installed horizontally or vertically to the pipeline. Pumps with motor power higher than 2.2kW, can only be installed vertically to the pipeline.
• The pump installation shall not allow the system pipeline tensile force to be transferred to the pump body.
• The pumps should be installed in the environment with sufficient cooling and the cooling air shall not be above 40 °C.
• If the pumps are installed outdoors, there should be covers to protect electric components from water.
• For the convenience of maintenance, there should be enough space above and below the pumps. Minimum 300 mm shall be kept for pumps with motor power lower than 5.5kW, and minimum 1000 mm for pumps with motor power higher than 5.5kW (including 5.5kW).
• To prevent noises and vibration and ensure the best operation, anti-vibration base shall be used in installation. Generally, cement base with the weight equal or bigger than 1.5 x pump weight shall be adopted.

For power ≤ 2.2kW

For power > 2.2kW

For power < 5.5kW

For power ≥ 5.5kW
