NKHY / PH Hand Type Oil Pump
The NKHY / PH Hand Type Oil Pump feeds an oil circuit by hand, so no electrical supply is needed anywhere in it. Built in resist-type and volume type builds, with two M10×1 outlets, one on each side.
How it works
Each pull of the lever displaces a measured volume into the main line. In a resist-type circuit that volume is divided between points in proportion, set by the restriction at each point.
The X and T builds carry a pressure take-off mechanism, which relieves the main line at the end of the stroke. That is what a positive-displacement volumetric distributor needs to re-meter, so those builds (and only those) can dose oil to each point through a volume type distributor.
Specifications
Model matrix by order code
The builds with a pressure take-off mechanism suit positive-displacement volume type distributors but cannot be used with resist-type distributors.

Installation notes
Fitting needs no electrical run: connect the outlet, or outlets, on M10×1 to the distributor's main tube and mount the pump within reach of the lever. Both outlets are provided on every build, one left and one right, so a resist-type circuit can feed two branches from a single pump; on a progressive circuit use one outlet only and cap the other.
Which build to order follows from the distributor it feeds. The plain NKHY-8 and PH-1600 are resist-type builds, with no pressure take-off at all. NKHY-8X and PH-1600T carry the take-off mechanism a positive-displacement distributor needs to re-meter, so those two suit a volume type circuit. The two builds are not interchangeable: ordering the wrong one gives a circuit that appears to run and lubricates nothing.
Before you order
- Resist-type and volume type builds are not interchangeable. Ordering the wrong one gives a circuit that appears to run and lubricates nothing.
- Two outlets are provided; use either or both. On a progressive circuit use one only.
Warranty
One year against manufacturing defect from date of invoice.
How it pairs
The NKHY / PH Hand Type Oil Pump is commonly specified alongside the VK / VM Resist-Type Distributor, the TCJ/TCZ Resist Type Distributor, the RH3 Type Volumetric Distributor, and the 35 Type Volumetric Distributor. That is the same recommendation carried on its own datasheet, not a generic same-category suggestion.
Used on
Industry applications
Ways, ball screws and LM guides on machining centres, turning centres and routers: metered oil to every point, and a wireless handwheel for the setter.
Tie bars, toggle pins and platens on horizontal and vertical machines: oil or semi-fluid grease, metered per point and re-metered every cycle.
Frequently asked questions
Does the NKHY hand pump need an electrical supply?
No. It runs entirely on the lever, so it suits machines and points with no spare electrical supply nearby.
Can I use both outlets at the same time?
On a resist-type circuit, yes: left and right feed two separate branches. On a progressive circuit use one outlet only and plug the other, or the sequence breaks.
How do I know which build matches my distributor?
NKHY-8 and PH-1600 are resist-type builds, with no pressure take-off mechanism. NKHY-8X and PH-1600T carry that mechanism, for a volume type circuit.
