SP / SMB8

Flow limiter for use in oil circulating lubrication systems

SP / SMB8 with signal transmitter
SP / SMB8 with signal transmitter

The SMB 8 flow limiter is designed to divide the main line flow into parallel, individual flows. The flow is generated independently of system pressure changes and virtually independently of viscosity, guaranteeing a constant flow. 

The SMB 8 provides a flow rate from 0,08 to 8 l/min (0.16–16.9 pts/min) and a pressure range of up to 200 bar (2 900 psi). The flow limiter offers oil flow monitoring with a signal transmitter or piston detector. These indicators create a fault signal when the flow rate drops to approximately 70%. Up to six SMB 8 can be combined on a mounting plate, providing a simple, space-saving installation and compact construction with only one inlet.

Features and benefits

  • Stable system regardless of pressure, temperature or viscosity changes
  • Easy start-up with fixed flow rate via pre-selected nozzle sizes
  • Adaptation of flow rate possible (nozzle exchange)
  • Optional ATEX version Ex II 3 cII CT6
  • Available as attachment to PSG2, PSG3 and VP on the same mounting plate
