321 metering devices with pre-lubrication cycle

For single-line lubrication systems

The 321 Series pre-lubrication, single-channel metering units are designed for single-line centralized oil and liquid lubrication systems. These metering units are installed directly at the lubrication point, eliminating the need for a lubricant pipeline to the lubrication point and the need for a lubricant pipeline itself. This is convenient in space-constrained environments. A choice of six types meets the requirements of various applications.

Technical characteristics and advantages

  • Specially designed single-channel metering device with pre-lubrication cycle
  • Direct connection to the main pipeline
  • No separate piping or fittings required
  • The threaded metering device is controlled by a pressure switch on the main line. Suitable for 4 mm (oil) and 6 mm (liquid lubricant) supply lines.

Application areas

  • Machine tools
  • Printing machines
  • Packaging machines
  • Textile industry
