Why does the CoolantLoop™ use air pumps?
Several reasons. FIrst, it s the right pump for the application. Centrifugal pumps will shear oil molecules into smaller pieces due to their high mechanical impact on the oil. Positive displacement pumps transfer packets of fluid which has litttle or no impact on the fluids being transferred. Our choice of air operated double diaphragm (AODD) pumps is based on the parameters required for the fluid being pumped. Coolant sumps by their very nature have a great deal of solids present. By choosing the right AODD pump we can specify the pumpable solids specification we d like to see for the application. Other positive displacement pumps, such as progressive cavity pumps, are quickly damaged by solids in the fluid being pumped. Another reason we use air operated pumps is that it means you don’t need electirical control panels, or electricians to hook it up or repair it. All you need to do is attach an air line and you re underway. Plug and play!
