Flow limiter series SMBM For base plate mounting, for use in oil circulation lubrication systems INNOVATIVE BUILDING BLOCK DESIGN FOR HIGHEST VARIABILIT Y Advantages: • Modular design • Constant oil flow • Self-adjusting metering • Identical oil flows despite different back pressures • Wide viscosity range • Virtually independent of viscosity • ATEX versions available • Easy system design • Space-saving installation • Easy start-up, no adjustment required • Effective monitoring

Oil circulation lubrication systems with SKF flow limiters Application System set-up Flow limiters are used in oil circulation lubrication systems. They feed specified individual oil flows to each lubrication point of the connected system. These individual oil flows are non-sensitive to system pressure changes and virtually independent of viscosity. A pump (1) sends oil to the main line (2). Attached to the main line are the flow limiters (3) or flow dividers which divide the oil flow into constant smaller flows. Optionally, progressive metering devices can be mounted downstream of the flow limiters...

How it works The total oil flow Qin entering a bank of flow limiters mounted on a base plate is divided up into individual oil flows Qout. The system pressure, being the input pressure p1, is the same for all flow limiters mounted on the same base plate. Single-flow version SMBM-X Every flow limiter has a spring loaded control piston with 1 plug-in nozzle D1 (SMBM-X) or 2 plug-in nozzles D1/D2 (SMBM-V) which acts as a differential pressure regulator. The non-adjustable plug-in nozzles (D1 or D1/D2) on the control piston determine the rated oil flow (→ figure 1 and 2) while D3 is a variable orifice...
