Detail view of Drip Oil Lubricator

Description
Drip feed lubricators are developed for dosing of oil, or other liquids, to one or more lubrication points. Their function is based only on gravitation — they are not able to exert pressure, so they must be placed above the lubrication point.
All types allow visual check of dosing through a sight glass window. Output from the lubricator connects to the lubrication point directly, or through short pipes. The flow is controlled by adjusting the needle valve and can be visualised from the built-in sight glass. The needle valve is joined with a toggle pin so the operator can manually stop and start the flow.
How a Drip Oil Lubricator Works
Oil flows from the transparent reservoir by gravity through a needle valve to the lubrication point. The needle valve controls the flow rate — turning it adjusts the number of drops per minute visible through the sight glass. Because the system is gravity-fed, no pump or electrical supply is required at the lubrication point. This makes drip oil lubricators the lowest-cost, most maintenance-free option for applications where a steady trickle of oil is sufficient.
SP Engineers manufactures drip oil lubricators in Faridabad, India — available in single-point and multi-point configurations.
Key Features
- Gravity-fed — no pump or power required at the lubrication point
- Transparent reservoir — oil level visible at a glance
- Built-in sight glass — confirm drop rate without opening the unit
- Needle valve with toggle pin — easy manual on/off and flow adjustment
- Single and multi-outlet models available
- Compatible with mineral and synthetic lubrication oils
Applications
Drip oil lubricators are used on lathes, milling machines, textile machinery, conveyor bearings, and other equipment where low-volume, gravity-fed oil lubrication is adequate. For applications requiring pressurised delivery, timed cycles, or multi-point distribution from a central reservoir, a motorized lubrication unit with metering cartridges is more appropriate.
