Chiller Applications for Our Pumps
Chiller systems remove heat from liquid for a variety of purposes through vapor compression or an absorption cycle. Magnetic drive pumps are needed to pump cooling liquids through the closed system, powering the process of heat removal. March pumps are your best option for long lasting chiller equipment.
Benefits of Mag Drive Pumps for Chiller Systems
Because the magnetic drive pumps are sealed and do not need a shaft coming out of the pump casing, there are some significant advantages to using a magnetic drive pump for your chiller system.
The pump design of magnetic drive pumps eliminates the need for pump seals which wear out and often leak. Additionally, magnetic drive pumps have minimal frictional surfaces that would generate heat, they transfer less heat during operation, making them ideal for use in chiller applications. Here are a few of the advantages of using a magnetic drive pump in your chiller systems:
Less heat generated by the pump functions and operation
No contamination risk of the pumped fluid
Less risk of fluid or vapor leaks
Higher flow rates at lower pressures
Magnetic drive pumps are reliable
Pump functions are quiet
Require very little maintenance
Couple easily with any system
Lower operational costs over a long period
How to Size and Select a Chilled Water Pump
Your chilled water pump needs to be correctly sized to create the right flow rates at the correct pressures. If there is not a sufficient enough flow, the cooling will not be sufficient. An oversized pump may generate too much pressure or too high a flow rate, creating stress on the system. It will also waste electricity and may cause excess wear on the system. Here is a Guide to Choosing the Right Chilled Water Pump. We believe a magnetic drive pump is ideal for chiller applications and we would be happy to help you in the selection of the right pump for your needs. Call or contact us today.
Parts of a Chiller Pump System and How They Work
Water chiller pumps are used to circulate chilled liquids through process equipment. The chiller cools the system and moves the heat away from the equipment and product. The cooled liquid absorbs heat from the equipment, warming it. Warmed liquid is pumped back to the chiller to be cooled again. Often a tank will be used to store liquids and a second pump may be required to move the chilling liquid to and from the reservoir. Magnetic drive pumps are ideal for use in chiller systems because the pump functions generate far less heat than other types of pumps.
Our American made seal-less centrifugal magnetic drive pumps are designed for chemical recirculation and heat transfer within chillers. A commonly used pump for these applications is the 320-CP, capable of generating a maximum flow of 3.3 gallons per minute at 1 foot, with a maximum head of 40 feet, or 17 psi. They can withstand a maximum internal pressure of 50 psi, and a maximum liquid temperature of 190 Fahrenheit. March products have pumped solvents and acids like Formaldehyde, Hydrochloric Acid, Nitric and Phosphoric acid.
