VK / VM Resist-Type Distributor
The VK / VM Resist-Type Distributor is a manifold of calibrated restrictions for oil circuits: the simplest and cheapest way to feed a group of lubrication points. Built with 2, 4, 6 or 8 outlets on Ø4 main and branch tube throughout, with Ø7 fixing holes.
How it works
Each outlet carries a calibrated restriction. Oil divides between the outlets according to those restrictions, continuously, for as long as the pump runs, so the dose a point receives is set by run time rather than by cycle count.
That makes the VK / VM the cheapest way to feed a group of points, and the most robust: there is no piston, no spring and no valve inside the block, so there is nothing to seize or to re-meter.
VK blocks come in two, four, six and eight outlets on 34 to 118 mm hole centres. The VM-4-8 is the same four-outlet function on 21 mm centres, for a mounting the VK will not fit.
Specifications
Model matrix by order code
VM is the compact four-outlet body: same function as VK-4-8 on 21 mm hole centres instead of 62 mm.

Installation notes
Mounting is by two Ø7 holes per body, on hole centres set by outlet count: 34 mm at VK-2-8, rising to 118 mm at VK-8-8, or a compact 21 mm on the VM-4-8 where the 62 mm VK-4-8 centres don't fit. Main and branch tube run Ø4 throughout on M8×1 ports, so the same fittings serve every outlet regardless of model.
The pump feeding it must run without a pressure take-off mechanism: the take-off relieves the very line pressure the VK / VM depends on holding, so fitting one wrong stops the manifold metering at all.
Before you order
- Resist-type distribution is proportional, not metered. Where each point needs a stated volume per cycle, specify RH-3 or 35 type instead.
- A pump with a pressure take-off mechanism is wrong for this block: the take-off relieves the line the VK depends on holding.
Warranty
One year against manufacturing defect from date of invoice.
How it pairs
The VK / VM Resist-Type Distributor is commonly specified alongside the NKHY / PH Hand Type Oil Pump, the TZ Type Oil Lubrication Pump, the HL Type Oil Lubrication Pump, and the TCJ/TCZ Resist Type Distributor. That is the same recommendation carried on its own datasheet, not a generic same-category suggestion.

Frequently asked questions
Does the VK / VM meter a fixed dose per cycle?
No. Flow divides between outlets proportionally, continuously, for as long as the pump runs. Where a point needs a stated volume per cycle, specify RH-3 or 35 type instead.
Which pump build does the VK / VM need?
One without a pressure take-off mechanism: a TZ or HL pump in the take-off-free build, or the NKHY-8 hand pump. A take-off device relieves the line pressure the VK / VM depends on holding.
What's the difference between VK-4-8 and VM-4-8?
The same four-outlet function on different hole centres: 62 mm on the VK-4-8, a compact 21 mm on the VM-4-8, for a mounting the VK won't fit.
