0.5L Hand Lubrication Pump, Adjustable 2-5 mL

What the 0.5 L Pump Does

The 0.5 L hand lubrication pump is the compact lever unit in our hand oil pump family. It suits small machines that carry only a few lubrication points, where a large reservoir would be more than the job needs. The transparent graduated tank shows the oil level at a glance, so the operator can top up before a point runs dry. Each stroke of the lever delivers an adjustable 2-5 mL of oil, and a relief passage limits over-pressure if a line becomes blocked. The pump mounts close to the points it serves, keeping the circuit short and the response direct.

Where the Compact Pump Fits

This pump fits a small machine with few points, where the operator can reach the lever and watch the tank. Typical hosts include short conveyors, small gearboxes, spindle units and packaging machines, each with a handful of points the operator passes during a shift. On machines like these, a compact visible-tank pump beats an oversized centralized system: the run is short, the dose is set at the lever, and the oil level stays in plain sight. When a circuit runs longer or serves more points, the machine-mounted L-type hand lubrication pump carries a larger reservoir and suits that duty better. Where the dose must stay fixed rather than adjustable, the Y-series hand oil pumps deliver a nominal 6 mL per stroke. The 0.5 L unit stays the compact choice within the family, and its adjustable output lets one pump cover several small points at different demands.

Installation and Setting the Dose

1. Mount the pump on a bracket close to the points it serves.
2. Fill the tank through the strainer with clean oil.
3. Turn the dose adjuster to the output the points need.
4. Prime the line until oil reaches the first outlet.
5. Stroke the lever and check delivery at the farthest point.

Oil Pump or Grease Pump

This is an oil pump, built for lubricants inside the 10-1000 cSt window. Grease will not pass its passages, so it must not be filled with grease at any time. Oil outside that window behaves poorly: thin oils meter unevenly and can slip past the dose adjuster, while thick oil barely moves through the passages and may stall the lever mid-stroke. Need grease instead of oil? A hand grease pump is the correct tool for that duty. Confirm the oil you plan to use sits inside the stated viscosity window before filling, and check for weeping under pressure at the joints after the first strokes.

Frequently Asked Questions

Is this pump for oil or grease?

Oil only. It is built for lubricating oil and must never be filled with grease.

How much oil does each stroke deliver?

Each stroke delivers an adjustable 2-5 mL, set with the dose adjuster.

Which oils can it handle?

Oils from 10 to 1000 cSt. Confirm your oil sits inside that window.

What pressure can it reach?

Up to 15 kgf/cm2, which is 213 psi.

How many lubrication points can it serve?

A few points on small machinery. For more points, a larger pump suits better.

Can I see the oil level?

Yes. The transparent graduated tank shows the level at a glance.

What outlet does it use?

A 6 mm outlet, matched to the line you run to the points.

Can it replace a machine-mounted piston pump?

For few-point duty, yes. Longer circuits suit the L-type pump instead.

Can it work in a cold workshop?

Yes, down to -10°C, provided the oil stays within its viscosity window.

Can IsoHiTech confirm the right pump before ordering?

Yes. IsoHiTech Lubrication Systems, founded in 2023, engineering since 2006, supplies this pump and the wider hand oil pump family. Send your point count and oil type to inquiry@isohitech.com or via the quote page for confirmation.
