Types of Refrigerant Pumps Used in Industrial Applications

In the world of industrial refrigeration, precision and performance are everything. The efficiency of cooling systems in sectors like food processing, pharmaceuticals, petrochemicals, and HVAC hinges on the quality of one crucial component: the Industrial Refrigerant Pump. At Hydrodyne Teikoku, we specialize in delivering cutting-edge pump technology engineered to meet the rigorous demands of these applications.

This blog dives into the various types of refrigerant pumps used across industries, helping you understand which pump type best suits your operational needs.

1. Canned Motor Pumps

Canned motor pumps are widely favored in industrial refrigeration systems for their leak-free design and high safety standards. Unlike conventional pumps that use mechanical seals, these pumps encase the motor and pump in a single hermetically sealed housing. This design eliminates the risk of refrigerant leakage especially important when dealing with hazardous or expensive gases like ammonia (NH₃) or carbon dioxide (CO₂).

Hydrodyne Teikoku is a market leader in canned motor pumps, offering unmatched durability, energy efficiency, and quiet operation. Their compact footprint also makes them ideal for space-constrained installations.

2. Centrifugal Refrigerant Pumps

Centrifugal pumps use impellers to move refrigerants and are ideal for large-capacity systems with moderate pressure requirements. These pumps excel in chiller systems and air conditioning applications where continuous circulation of refrigerant is essential.

Hydrodyne’s centrifugal Industrial Refrigerant Pump designs offer smooth flow, low pulsation, and high performance under variable load conditions. With corrosion-resistant materials and precision-balanced impellers, they ensure minimal maintenance and long service life.

3. Positive Displacement Pumps

Positive displacement pumps, including gear and screw pumps, are typically used when consistent flow rates are essential, regardless of system pressure. These pumps are ideal for applications where the refrigerant is in a mixed phase or contains entrained gases.

Industries such as chemical processing or cryogenic refrigeration benefit from Hydrodyne’s positive displacement models due to their ability to handle viscous or multiphase refrigerants with superior reliability.

4. Submerged Motor Pumps

Designed for installation inside refrigerant storage tanks or flooded chillers, submerged motor pumps offer efficient cooling of both pump and motor. Their configuration reduces vibration and allows for quiet operation. These pumps are particularly suited for low-temperature applications in food preservation and ice manufacturing.

Hydrodyne’s submerged motor refrigerant pumps feature precision sealing systems and advanced thermal management, helping maintain optimal performance even under extreme conditions.
