Bijur Delimon – Meter Unit FJB-4: Extra Fast Flow, Junction Type B
L. Dewitt's SKU #: B2499 | Mfr Part #: B2499The Bijur Delimon B2499 Meter Unit (Type FJB-4) is a precision oil proportioning device for Single Line Resistance (SLR) cyclic lubrication systems. The FJB is the most commonly used meter unit junction type — it threads into a standard Bijur junction or junction header and delivers "Extra Fast" metered oil via a 5/32" tail tube to the bearing point.
Regulated Extra Fast Flow
As a FJB-4 model, this unit delivers Extra Fast flow, providing a high-volume oil delivery for the largest or most critically loaded bearing points in the system. Typically specified for oversized journals, large-diameter slides, and applications with extreme load or speed requirements.
Cyclic System Integrity
An integrated 5 lb check valve ensures one-directional oil flow (arrow stamped on 3/8" hex body) and prevents the tail tube and distribution lines from draining back during the pump's off cycle. For cyclic lubrication systems only. Not compatible with continuous-flow pumps.
