VSL dosing devices

For dual-line lubrication systems

Robust VSL metering units made of galvanized steel are designed for dual-line systems with pressures up to 400 bar (5800 psi) Inclusive. These metering devices can have up to eight outputs, and each pair of outputs is equipped with an indicator for visual monitoring. VSL metering devices can also be equipped with wear-resistant proximity switches or piston position sensors for monitoring. Additional features include corrosion-resistant material.

Technical characteristics and advantages

  • Simple transverse hole pattern with external screw
  • One-piece construction improves strength and simplifies replacement
  • Efficient operation over a wide temperature range
  • Convenient monitoring

Application areas

  • Cement plants
  • Quarry excavators
  • Steel mills
