DSV Progressive Systems Metering Devices Grease Distributor Progressive

Short Description:


Progressive Lubrication System(PRG)
Progressive lubrication systems consist of a lubricator, progressive distributors, pipeline accessories and controllers. Features include: accurate metering of volume depending on piston diameter and stroke, easy installation, adjustment and maintenance. The PRG system is widely used in mining, steel mills, metallurgy, vehicles, harbors, construction machinery and other industries. The lubricant used is from NLGI-000 toNLGI-2, while system pressure ranges from 20 to 45Mpa. The filter element is 150μ.The progressive distributor is divided into two kinds of distributors: a center progressive distributor and a model progressive distributor. There is a choice of segment combinations, effectively ranging from periodic to near continuous lubrication.
Advantages: Precise discharge – All points can be fed and monitor individually – Trouble free installation – Easily pinpoints system issues

Product Detail

Product Tags

The DSV series progressive distributor is designed for small-size progressive lubrication systems. They are a cost efficient solution for supplying multiple lubrication points with relatively small volumes of oil and grease. The MVB series can be used with machine tools, processing machinery, presses, textile, printing and packaging machinery. The DSV is also suitable for mobile applications, including off-road equipment.

1 Oil Outlet 
MVB Standard Flow : 0.17ml

2 Distribution principle

The plunger sleeve is connected through the oil hole to establish pressure. As long as there is pressure to allow the lubricant to enter the oil mouth, the distributor will run continuously in a progressive manner and fill with a constant displacement.

Once the supplied pressure lubricant stops, all of the plungers in the dispenser will also stop moving. Therefore, by operating a specific indicator to observe the movement of an oil discharge plunger, the operation of the entire distributor can be monitored. In the event of a blockage, an alarm can be issued.
4.Oil Outlet
The plunger which closest to the oil inlet ,discharges the lubricant oil first from the farthest oil outlet , and the other plungers in the valve body discharge the quantitative lubricant through the next oil outlet.
