Milk Vacuum Pump

Vacuum pumps are used in dairy farms to create suction to extract milk from the cow and move the milk to the cooling system. These pumps are also used to clean the milk pipelines between milkings by flushing the lines with wash water. The load on the pump varies throughout the milking process, so the VFD allows the pump motor to adjust the speed according to the demands of the system. The VFD varies the electricity frequency going into the motor that allows the motor speed to vary. The VFD is automatically controlled by a vacuum or pressure transducer that measures changes in pressure in the milking suction system. VFDs or variable speed drives (VSD) installed with existing milk vacuum pump equipment, or installation of new milk vacuum pump equipment with a VSD/VFD, are eligible for a rebate.
