The 1 kg automatic oil lubrication pump is the compact member of the automatic oil pump family from IsoHiTech Lubrication Systems, built for single machines and tight mounting spaces where a larger reservoir does not fit. It delivers timed, intermittent oil cycles to a small number of lubrication points, trading reservoir volume for a footprint that fits inside crowded cabinets and machine frames.

Why choose a 1 kg reservoir
Reservoir size is a refill-interval decision constrained by mounting space. Point count alone does not size the reservoir; daily oil consumption does. A single milling machine or CNC lathe with a handful of points typically uses only a few milliliters per day at ordinary cycle settings, so even a 1 kg tank covers long stretches between refills. Where the machine sits inside a packed production line, the compact body and cabinet-friendly mounting matter more than squeezing out extra refill days.
If your machines run several shifts with more points or longer run time per cycle, step up to the 3L automatic oil lubrication pump or the 4L lubrication pump from the same family.
Control and connections
The pump works from a built-in timer or a PLC signal, delivering short, timed cycles rather than a constant flow. Outlets accept 4 mm and 6 mm oil lines; the lubrication tubing and hose selection guide covers line sizing and routing. Three voltage options (24V DC, 220V AC, 380V AC) cover most machine-tool electrical cabinets, and the IP65 enclosure tolerates coolant splash and shop dust.
What this page does not claim
- No viscosity range is published for this pump. Use the oil grade your machine builder specifies; viscosity compatibility for your oil is confirmed at order.
- The timer is an open-loop schedule. It does not sense whether the machine is running, and a running pump motor does not prove that oil arrived at every point.
- Reservoir level is checked visually on the standard unit. Low-level alarm options are confirmed at order rather than assumed.
FAQ
What is a 1 kg automatic oil lubrication pump?
It is a compact automatic oiler with a reservoir of about 1 liter that feeds metered oil to machine lubrication points on timed cycles. It is designed for single machines with one to four outlets and limited mounting space.
What machines does it suit?
Compact CNC machines, milling machines, lathes, textile machinery, and similar equipment with a small number of oil points. It fits best where cabinet or frame space is tight and an operator can refill the reservoir regularly.
How many lubrication points can it serve?
The pump offers one to four outlets. Each outlet feeds a line or a metering network, so the practical point count depends on how the distribution is laid out on the machine.
How does the timer or PLC cycle work?
The timer delivers short, intermittent cycles: a brief run period followed by a pause, repeated on the schedule you set. A PLC signal can trigger the same cycle from the machine control. The pump does not run continuously.
What voltage options are available?
24V DC, 220V AC, and 380V AC. Confirm the control voltage available in your machine cabinet before ordering.
How often does the reservoir need refilling?
There is no fixed schedule; the interval depends on your cycle settings and the number of points served. Light duty stretches a 1 kg reservoir over a long period, while frequent cycles shorten it, so check the level visually on a routine that matches your usage.
What oil grade should I use?
Use the oil grade your machine builder specifies. Because no viscosity range is published for this pump, compatibility with your particular oil is confirmed at order.
Should I choose oil or grease for my machine?
High-speed spindles and slideways generally favor oil, while slow or heavily loaded points often favor grease; see the grease pump range for the grease side. When in doubt, follow the machine builder’s recommendation.
What should I specify when ordering?
Tell us your voltage, outlet count, oil grade, and approximate point count so the configuration can be confirmed. You can request a quote with these details, and the same contact page handles technical questions.
