The volumetric system is based on Positive Displacement Injectors (PDI). A precise, predetermined volume of oil or soft grease is dispensed to each point unaffected by
temperature or viscosity of the lubricant

Both electric and pneumatic pumps are avaible to ensure a discharge of up to 30 cu.in./minute via a range of injectors extending from 0.002 to 0.06 cu.in. per cycle
