Detail view of metering cartridge

Description
The metering cartridge is a kind of mini-cylinder with a check valve, where stroke of piston determines the amount of ejected oil.
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.
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
