Ограничитель расхода SMB 14

Flow limiter SMB 14

For circulating oil lubrication systems

The SMB 14 flow limiter is designed to divide the flow in a main pipeline into separate parallel streams and restrict them as required. The flow is created independently of system pressure and virtually independent of viscosity, ensuring a constant flow rate.

SMB 14 provides flow rates from 25 to 90 l/min (52.8–190 pints/min) and pressure range up to 50 bar (725 psi). The limiter has a built-in gear-type flow indicator for electronic and visual monitoring of oil consumption. Each rotation generates a signal providing flow information.

The SMB 14 flow limiter is the ideal solution for applications with changing ambient temperatures and the need for a stable oil flow, such as circulating oil lubrication systems.

Features and Benefits

  • Stable oil flow regardless of changes in pressure, temperature or viscosity
  • Visual and electronic monitoring to indicate actual consumption
  • Easy start-up with a fixed flow rate pre-set by selecting the nozzle size
  • Adaptation of flow rate using plug-in nozzles
  • Optional ATEX version
  • Optional connection to enterprise data management system
  • Extremely robust construction

Application areas

  • Mining, cement and oil and gas industries
  • Machines for metal forming, machine tools
  • Pulp and paper industry
  • Industrial gearboxes
