VOLUMETRIC SYSTEM

The volumetric type lubrication system focuses on applying measured volumes of oil to the multiple lubrication points on equipment or machinery.
The distribution equipment (Dester Plunger or Dester Block) measures a specified amount of oil and then proceeds to forward the lubricant intermittently to the lubrication points.
This accurate and intermittent distribution via the distribution equipment is induced by volumetric type pump.
Motorized lubrication pumps for this system, will run and halt in intermittent cycles through the use of a controlling mechanism (Eg. IC Timers).
Distribution equipment for the volumetric type system can be separated into 2 main categories.
Direct pump pressure or spring pressure induced discharge methods.
The first utilizes the pump’s discharge pressure to eject the oil from within the pistons. The later method utilizes the pump’s pressure to replenish the pistons with oil and relies on the internal spring to displace the oil.
As the displacement of pressure is required for the volumetric type distribution equipment to operate, all volumetric type pumps possess pressure displacement mechanisms.
