Pre-lubrication metering devices for use in single-line lubrication systems

Single-line metering device model 83748
Series SL-44 metering devices were developed for single-line, centralized lubrication systems dispensing fluid or semi-fluid lubricants. Lubricant output is externally adjustable, and the indicator stem permits a visual check of metering device operation. These carbon steel metering devices feature fluoroelastomer packing. Metering devices with fluoroelastomer packing (indicated by black adjustment caps) are used for applications requiring heat resistance or when a lubricant requires it for compatibility.

Features and benefits:

  • Screw-in type, single-port metering device for pre-lubrication affixed by adapter bolts
  • Suitable for use with manifolds having one to five ports to match number of lubrication points
  • Output is externally adjustable
  • Indicator stem permits visual check of operation
  • May be combined in a circuit with SL-41, SL-42 and/or SL-43 metering devices
  • Individual metering devices can be removed easily for inspection or replacement
