Variable Speed Vacuum Pump Control

The ATL Variable Speed Vacuum Pump Control is designed to make vacuum production more effective and efficient.

The system controls the vacuum pump(s) speed and air flow to ensure that vacuum is produced when required by the milking parlour. Therefore, reducing the energy consumption and electricity costs.

Variable Speed Vacuum Pump Control


  • The Variable Speed Vacuum Pump Control allows more efficient production of vacuum as vacuum is produced based upon demand.
  • Vacuum demand will change throughout milking depending upon whether units are being attached, units being removed etc.
  • This reduces energy use and therefore reduces electricity expenditure.
  • Additionally, the system can reduce noise levels and extend the life of the vacuum pump and motor by reducing wear and tear.

How it works

  • System uses digital vacuum sensor to constantly monitor the vacuum level.
  • Digital vacuum sensor either included in ATL Auto Wash Pro automatic plant washer or ATL Remote Vacuum Sensor.
  • System will only increase or decrease the speed of the vacuum pumps if the vacuum level changes.
  • The vacuum level will change based on the demand for vacuum – putting a cluster on an animal increases demand and removing a cluster from an animal decreases demand.
  • Set minimum and maximum vacuum pump speeds to match your vacuum pump specifications.
  • Digital vacuum sensor and invertor drive in separate boxes to maximise flexibility during installation.

Inverter Unit

  • Available for 1 phase input versions for motor sizes 2.2kW, 3.0kW, and 4.0kW. IMPORTANT – Requires 3 phase motor on vacuum pump.
  • Available for 3 phase input versions for motor sizes 2.2kW, 3.0kW, 4.0kW, 5.5kW, 7.5kW and 11kW.
  • Invertor unit includes filter and choke to prevent electrical interference and is therefore suitable for use with 134.2kHz RFID systems.
  • Includes manual run setting on the front of the invertor for emergency control.
