Compliance and Restrictions

  • This item is restricted for international sale.


This vacuum switch is intended to be used as a control device to eliminate the need to attend a pump while a limited liquid source is being pumped. By shutting off the electric motor when the liquid is depleted, it helps to protect the pump and the drive from breakdown due to dry operation.
