Manufacturer of metering cartridge
Description
A metering cartridge, also called a lubrication cartridge, is a small precision cylinder with a check valve, where the stroke of the internal piston determines the amount of oil ejected at each cycle. It's the standard metering device used at individual points in a centralized oil lubrication system.
It is designed such that every time when pump is operated, it ejects out predetermined amount of oil. When pressure is released, the cartridge gets recharged. For proper recharging of metering cartridges there shall be a small time gap in between subsequent operations of pumps.
Maximum permissible pressure for metering cartridge is 40 Kg/cm2. Minimum working pressure is 8 Kg/cm2 and pressure shall drop to less than 1 Kg/cm2 in between successive operations.
What Does "cc" Mean on a Metering Cartridge?
The dosage figures in the model table below (0.01 cc, 0.25 cc, 1.0 cc, and so on) are measured in cubic centimetres, the volume of oil ejected per stroke. 1 cc equals 1 millilitre. A cartridge marked "0.25 cc" delivers exactly a quarter of a millilitre of oil each time the pump pressurises the line, regardless of how many other cartridges are on the same circuit.
Common Applications
Metering Cartridges are used in Single Shot Oil Lubrication System on various machines such as Machine Tools, Textile Machines, Die Casting Machines, Sheet Metal Working Machines, Shearing and Press Brakes, Metal Forming Machines, Rubber Mixing Machines, Printing Machines, Injection/Blow Moulding Machines, Presses and Hammers, Packaging Equipment, Pharmaceuticals Machines, Food Processing Equipment etc. We are the leading manufacturers and suppliers of Metering Cartidges from Faridabad, India.

How a Metering Cartridge Works
A metering cartridge is a precision volumetric dosing device installed in the distribution line of a centralized lubrication system. When the pump delivers lubricant under pressure, the cartridge's internal piston displaces a fixed, pre-set volume of oil to the lubrication point. When system pressure drops at the end of the pump cycle, a spring returns the piston to its original position, ready for the next cycle.
Because each cartridge delivers an exact, repeatable dose regardless of line length or back pressure, metering cartridges ensure every lubrication point receives the correct amount of lubricant, no more, no less. This is critical for machine tools with many lubrication points spread across guideways, ballscrews, and spindle bearings. They are used with a motorized lubrication unit or hand operated pump and mounted on a manifold block.
Key Advantages
- Precise, repeatable oil volume per cycle, independent of line pressure variation
- Individual cartridges can be sized differently for points with different oil requirements
- No electrical connection required, purely mechanical operation
- Easy replacement without draining the entire system
- Compatible with most centralized oil lubrication pump units
- Used extensively on CNC machine tools, machining centres, and transfer lines
