Liquid Ring Vacuum Pump Applications

Graham liquid ring vacuum pumps are commonly used in the production of food. Most of the applications in the food industry are geared toward the removal of water. Concentrating fruit juice, adjusting the boiling point (temperature) of water during cooking, and flash cooling after a food item has been cooked are all common processes where liquid ring vacuum pumps may be found. Materials of construction for these systems are normally cast iron or 316 stainless steel. Many of these systems are supplied with a precondenser to remove most of the condensible load upstream of the liquid ring pump. This results in a much smaller vacuum system.
