What a Single Line Oil Distributor Does
A single line oil distributor is the metering component in an oil circuit. One main line feeds it, and each outlet delivers a fixed oil volume per cycle to one point. It does not split flow like a passive junction. It measures a set dose at every outlet while the pump pressurizes the line.
Use this component when you need repeatable oil delivery to bearings, slides, chains, or other points in a central lubrication system. Each outlet can have a different metered volume, so one distributor can serve points with different needs. The pump, line, and distributor work together: pressure moves oil, then the line vents so outlets reset.
Declared Specifications
| Outlets | 2 to 12 |
| Metered volume per outlet per cycle | 0.01 to 1.5 cc |
| Working pressure range | 8 to 45 bar |
| Optional high pressure body | rated to 100 bar |
Confirm outlet count, dose per outlet, and body rating when you order. The table lists the declared range; your assembly is built to your specified dose.
How the Metering Cycle Works
The pump pressurizes the one main line. Oil enters the distributor and each outlet meters its set volume. A metering element controls the dose, so the outlet delivers the same volume each time the line reaches working pressure.
When the pump stops, the line vents. Venting lets the metering elements reset for the next cycle. The next pump cycle pressurizes the line again, and each outlet meters its dose. This pressurize and vent sequence is critical: without a clean vent, outlets may not reset for the next dose.
Some systems use a cycle indicator at the pump or distributor. Watch it to confirm the line pressurized and vented. A failed outlet or blocked point does not always stop oil delivery to other outlets, so use point checks too.
Matching the Distributor to Your Pump
The pump must reach the working pressure of the distributor and vent the line cleanly after each cycle. If the pump cannot vent, the metering elements stay pressurized and cannot reset. Check pump control, line length, and line size as one circuit.
Size the oil pump reservoir to the number of points and the cycle rate. More points and faster cycles use more oil. A reservoir that is too small may run dry; one that is too large adds weight without helping.
Use the pump and distributor as a matched pair. If the pump cannot hold pressure or vent fully, the metering cycle will be unreliable. Describe the pump, line size, and point list when asking for help.
Oil Distributor versus Grease Manifold Block
A grease manifold block is a passive junction. It divides grease flow to several points but does not meter oil at each outlet. A metering oil distributor measures a set dose at each outlet per cycle.
Fault behavior differs. On a passive block, a blocked point can change flow to other points because the block only splits flow. On a metered oil distributor, a blocked point shows at the cycle indicator or through a point check, not by stalling neighbors.
Choose the metering distributor for oil points that need a known dose. Choose a passive block only for simple flow division and no metering. The two parts look similar but do different jobs.
Sizing Outlets per Lubrication Point
Start with the oil need of each point. A bearing, slide, chain, or gear set needs a specific dose per cycle based on load, speed, and size. Use that dose to select the metering element.
You do not have to use every outlet. Unused outlets are closed with plugs. That lets you buy one body size and leave room for future points while keeping the circuit sealed.
Confirm doses at ordering. Give the point list, dose per point, oil type, viscosity, and cycle rate. If unsure, contact for a quotation and describe the machine. The distributor is built to the dose you approve, so order details matter.
Frequently Asked Questions
Is this a metering block?
Yes. It is a metering distributor for oil systems, not a passive junction block.
Does every outlet deliver the same volume?
No. Each outlet has a set metered volume, and volumes can differ per point.
How do I adjust the oil volume for each point?
Change the metering element or selector setting for that outlet. Confirm the target dose with your supplier before assembly.
What oils and viscosities can it handle?
Use clean mineral oil or synthetic oil compatible with seals and wetted parts. Viscosity must suit the pump and metering element.
What working pressure does it need?
It needs enough pressure to meter every outlet and reset after venting. The standard range is 8 to 45 bar, with an optional body rated to 100 bar.
Can I add outlets later?
Yes. You can add outlets later if the body has spare positions, then close unused positions with plugs until needed.
How do I know the system cycled?
Watch the cycle indicator during each pump stroke. A moving indicator shows the line pressurized and vented.
How is it different from a passive grease manifold?
A passive grease block only splits flow and does not meter oil. A blocked point shows at the cycle indicator, not by stalling neighbors.
What should I state when ordering?
State oil type, viscosity, temperature, cycle rate, and required dose per point. Share your point count and use our contact page for a quotation.
