QSL

High-pressure metering devices for use in single-line lubrication systems

QSL metering device

QSL metering devices are designed for 300 bar pressure. As a result, NLGI 2 greases can be pumped at temperatures below zero without problems. All metering devices operate independently of each other. This means that in the event of a blockage or fault of one metering device, all other metering devices will continue to supply lubricant. A control pin on top shows proper function of each injector.

Features and benefits:

  • Suitable for use with manifolds from 1 to 6 ports to match number of lube points; must be ordered separately
  • Corrosion-resistant, black-cromated or nickel-plated surface
  • Each indicator stem permits visual check of operation
  • Can be removed easily for inspection or replacement
  • Controlled via main line
