Description
Bijur Delimon – Control Unit CRA-5/0: Extra Extra Slow Flow, Reverse Type A
L. Dewitt's SKU #: B7142 | Mfr Part #: B7142The Bijur Delimon B7142 Control Unit (Type CRA-5/0) is an oil proportioning device for continuous-flow lubrication systems. The CRA is a reverse-flow control unit — the inlet connects to a pressurized internal oil passage within the machine body and the outlet connects a tail tube to the bearing point. Calibrated to "Extra Extra Slow" output.
Calibrated Extra Extra Slow Output
As a CRA-5/0 unit, this control unit is calibrated to the Extra Extra Slow output rate — the minimum end of the C-series range. It is specified for bearing points or slides that require only the most minimal trace of lubrication in a continuously running system, where even a slight over-delivery would cause contamination or pooling.
Continuous System Design
For continuous-flow lubrication systems only. No internal check valve. Do not use in cyclic pump systems.
