TQWT Horizontal End Suction Pump for Cooling Tower

The TQWT Series is a high-efficiency horizontal end suction centrifugal pump specifically designed for cooling tower and condenser water circulation systems. The discharge nozzle of TQWT series cooling tower pumps typically features a radially pointing upward design(i.e., the discharge port is oriented 90° perpendicular to the pump shaft, facing straight upward). The core advantage is that can be space-saving including ideal for compact cooling tower equipment configurations and enable vertical piping layout, reducing the need for horizontal elbows. Based on a mixed-flow hydraulic model, the pump efficiently delivers high flow rates at low head, making it ideal for cooling tower applications. It offers horizontal installation with speeds of 2960/1480 RPM and 28 model variants to accommodate diverse spatial layouts and circulation requirements.

Applications:

Provides continuous water circulation in closed-loop cooling systems for power plants, manufacturing facilities, enhancing heat dissipation efficiency.
Circulates cooling water in injection molding machines, die-casting systems, and other high-heat industrial processes to ensure operational stability.

Product Features

Easy Installation

The motor is fixed directly to the base frame, eliminating the need for additional support installation on the pump body end, ensuring quick and hassle-free setup.

Corrosion-Resistant & Long Service Life

Flow components (pump body, impeller, etc.) are made of high-quality cast iron or stainless steel, with electrophoretic coating (E-coating) or anti-corrosion spray treatment for enhanced rust resistance and durability.

Low Vibration & Noise

Direct-coupled structure minimizes transmission losses for smoother operation. Precision dynamic balancing reduces vibration and noise, making it ideal for noise-sensitive environments.

High Efficiency & Energy Saving

Optimized hydraulic design with flow channels ensures high operational efficiency, significantly reducing energy consumption.

What's more, impeller and pump casing are engineered with advanced hydraulic models for higher efficiency.

Wide Applicability

Compatible with both closed and open cooling tower circulation systems. Offers a broad range of flow and head options to meet diverse industrial cooling and HVAC applications.

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.
