Flow limiter SMB 13

For circulating oil lubrication systems

The SMB 13 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 13 provides flow rates from 6 to 38 l/min (12.6–80.3 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 13 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 for Ex II 2G with TX Gb, Ex II 2D with TX Db
  • 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

Ordering information
The product can be configured using a configuration code. The flow rate must be adjusted according to the insert nozzle size, as shown in the table below.
24-2713-0… SMB13 without monitoring, … plug-in nozzle size = see table below
24-2713-1… SMB13 with electrical monitoring, … insert nozzle size = see table below
24-2713-2… SMB13 with monitoring for ATEX, … plug-in nozzle size = see table below
24-2713-3… SMB13 without monitoring for ATEX, … plug-in nozzle size = see table below
ATEX versions are available upon request for ATEX only (EX II 2G with TX Gb, EX II 2D with TX Db), without monitoring, or with a piston sensor. Add "ATEX" to the end of the part number.
