TQLT Vertical Inline Pump for Cooling Tower

The TQLT cooling tower pump is a specialized centrifugal pump developed by Tianquan for closed cooling towers and condenser water circulation systems. Featuring a cantilever design with standard flange connections for inlet and outlet, it operates at a maximum pressure of 1.0 MPa and temperature of 80℃. The pump utilizes a direct motor connection, where the impeller is mounted on the motor’s extended shaft, eliminating the need for an independent bearing system. Radial and axial forces are fully supported by the motor bearings.

Applications:

Suitable for commercial and industrial buildings to circulate condenser water in cooling towers, ensuring stable temperature control for air conditioning systems.
Supports precision cooling in data centers by maintaining consistent water flow in chilled water systems, preventing equipment overheating.
Integrates with geothermal and solar thermal cooling systems to optimize energy transfer and heat exchange.

Model selection instructions

After sales1

Users' selection shall not be limited by the performance parameters list. Parameters in the catalog are only for reference. We could design and manufacture the product according to the actual requirements. If there is a special selection beyond the sample performance parameters, please get in touch with our technical support.

If the selected model is close to performance parameters, generally standard impeller pumps and high-speed pumps are preferred. (NPSH shall meet the requirements).

If a high-voltage motor or special motor is required, please DO NOT make the foundation according to the installation dimension of the sample. Our technical support shall customize the drawings.
