Refrigeration System Applications for Our Pumps
Refrigeration is an essential element for many businesses and industries. From allowing the transportation and purchasing of various kinds of food to the production of various hydrocarbons to the preservation of perishable medicines, refrigeration has truly transformed society. But for refrigeration systems to work effectively, you need effective and reliable pumps such as those offered by March Pumps.

Choosing a Pump for Refrigeration Systems
Because they’re responsible for moving liquids (which can lead to multiple kinds of hazards if leakage or catastrophic failure should occur), pumps for refrigeration systems need to be chosen carefully. Selection criteria should involve consideration of the following:
- Pump Capabilities and System Design. When purchasing any pump, a buyer should consider the pump’s thresholds for pressure, horsepower, power requirements, maximum flow, maximum head, and the like. However, concomitant required information also includes the nature of the system itself. What will you be cooling? How quickly will you need the coolant to flow? And what exactly will that coolant be?
- Coolant Characteristics. Some refrigerants have more challenging characteristics than others and can entail some risks when using. A system failure could lead to environmental contamination or the injury of personnel. Ensure that your pump not only has the appropriate power to move the refrigerant through your system but is also constructed of materials that won’t degrade or corrode. (Note that magnetic drive centrifugal pumps mitigate a significant amount of leakage risk since the motor shaft doesn’t penetrate into the pump, eliminating the need for a seal that could fail.)
Common Roles for Pumps in Refrigeration
Refrigerant pumps are used for more than simply powering space-cooling systems. Some common roles for pumps in refrigeration include the following:
- Tanker Unloading. Due to its low cost, ammonia is a preferred refrigerant in commercial applicants, and transferring it from location to location requires the use of tank trucks. Pumps are employed to move the ammonia to its final destination.
- Batch Chemical Processes. Batch processing is a manufacturing method that’s often used in the production of industrial refrigerants.
- Specialty Chemicals. Refrigerants are constantly undergoing new chemical formulations, and pumps are involved in their production and storage.
- Column Reflux. A method of distillation, reflux will sometimes involve the use of refrigeration, which requires a pump.
In order to perform properly, refrigeration systems must be able to handle liquid transfer for heating and cooling operations. Seal-less mag drive pumps like March Pump’s industrial 809-SS-HS pump model are ideal for maintaining liquid flow and internal pressure in cooling systems. Built with stainless steel, Teflon and silicone, our pumps have dispersed cutting oils, ethylene glycol, hot water and saltwater. Our pump models can generate a maximum flow of 7 gallons per minute at 5 feet, with a maximum head of 18.6 feet.
March pumps come with a one year warranty against defects in materials and workmanship, and are manufactured in the United States in our suburban Chicago facility.
