What the DJF1000 Does
The DJF1000 is a Series 1000 progressive divider valve manifold. It takes one lubricant input and splits it into multiple metered outputs. Inside the block, each piston must finish its stroke before the next piston starts. That fixed order means every lubrication point is served in sequence, cycle after cycle. The design suits medium-duty machinery: CNC machining centers, packaging lines, conveyors, and mixers. Where a single pump feeds several bearings or slides, the DJF1000 divides the flow into measured doses instead of letting lubricant take the easiest path. For heavier duty cycles, see the DJF3000 progressive blocks; for a smaller frame, the DJF2000 progressive block covers lighter demand.

Valve Sections and Part Numbers
Each working section carries its own part number and discharge volume. The letter in the code tells you the outlet count: T means twin outlets, S means single outlet. The 05, 10, 15, and 20 numbers mark the discharge size step, from smallest to largest.
| Section | Part number | ml per cycle | Outlets |
|---|---|---|---|
| 1000-05T | 20710-05T | 0.08 | 2 |
| 1000-05S | 20710-05S | 0.16 | 1 |
| 1000-10T | 20710-10T | 0.16 | 2 |
| 1000-10S | 20710-10S | 0.32 | 1 |
| 1000-15T | 20710-15T | 0.24 | 2 |
| 1000-15S | 20710-15S | 0.48 | 1 |
| 1000-20T | 20710-20T | 0.32 | 2 |
| 1000-20S | 20710-20S | 0.64 | 1 |
How the Progressive Sequence Works
Lubricant enters the inlet port under pump pressure. The first piston in the stack strokes fully, pushing its measured volume to its outlet. Only when that stroke completes does the next piston begin. This repeats through the block in a fixed order that never changes between cycles. Because the pistons are mechanically linked in series, a blocked outlet stops the whole block. That is a safe interlock: pressure cannot build past the pump setting, and no point downstream receives a double dose while another starves. Cycle indicators on the block show piston movement at a glance, and optional switches can feed a controller for remote monitoring.
Configuring an Assembly
A DJF1000 assembly needs at least 3 sections and can carry up to 8. You can mix section sizes in one block: small sections for light bearings, large sections for heavy points that need more lubricant per cycle. Indicators mount on designated sections, so confirm their position when you order. Custom inlet and outlet diameters are available on request. The physical build order is always the same: inlet section first, working sections in the middle, end section last. If you need higher discharge volumes or a different divider family, the JPQ progressive blocks are an alternative. Send your point list through our quote request page and we will map sections to points.
Installation Notes
Mount the block vertically where possible; this helps the pistons return under gravity and keeps air pockets out. Keep inlet pressure between 1.4 and 16 MPa. Never block an outlet to silence a line; a dead-ended outlet stops the entire sequence. Keep components clean during assembly, and cap open ports until lines are connected. Check the cycle indicators on a daily walk-round so a stalled block is noticed before a bearing runs dry. For assembly questions, reach us through the quote request page.
Frequently Asked Questions
What is a DJF1000 progressive block?
It is a divider manifold that meters oil or grease to multiple points in a fixed sequence.
How many lubrication points can it serve?
It serves 1 to 18 points, using 3 to 8 valve sections.
How much does each outlet deliver?
Each outlet delivers 0.08 to 0.64 ml per cycle, depending on section size.
What happens if one outlet blocks?
The whole block stops. Find and clear the blocked line before restart.
Can different section sizes be mixed?
Yes. The modular design lets you mix T and S sections in one assembly.
Which lubricants work?
Use oil of viscosity grade 68 minimum, or NLGI 000 to 2 grease.
What pressure does it need?
It needs 1.4 MPa minimum to start and 16 MPa maximum.
Can sections be added later?
Yes. Add working sections between the inlet and end sections.
How is it monitored?
Cycle indicators show piston movement, and switches can feed controllers.
