Dual-line metering devices

Lubricant metering devices for dual-line automatic lubrication systems


Working principle:

  • In contrast to single-line or progressive systems, dual-line systems are designed with two simultaneous feed lines. One of the main lines is pressurized while the other is relieved of pressure. In order to perform a complete lubrication cycle, both main lines have to be alternately pressurized and relieved of pressure. 
  • The metering devices measure an adjustable quantity of lubricant per lubrication cycle. Each lubrication point has its own lubricant outlet. A dual-line metering device can serve even or odd number of lubrication points.
