Metering Cartridges

In single shot centralised lubrication system, amount of oil at each lubrication point is controlled by using the element known as ‘METERING CARTRIDGE’.

For each lubrication point at least one metering cartridge shall be used.

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 (min. 1 minute).

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.
