Description. The MVB lubrication system is a single
line, series progressive system which divides pump output into predetermined proportional amounts and distributes these amounts to the progressive series of divider valves. MVB lubrication systems were developed to handle the higher operating pressures typically seen in the gas engine and compressor industry and to offer the advantages of a series progressive system over a box lubrication system.

Configurations. With two pump sizes, 10 final drive gear ratios and six drive configurations, any lube rate between 2-300 pints per day can be achieved. The MVB system provides lubricant at pressures up to 8,000 psi, among the highest in the industry.

Lubricant Cleanliness. A filter/primer assembly
is available with a choice of a 10 or 25 micron filter element that prevents contaminants or particles from reaching the pump or the lubrication point. It has a unique self-scrubbing feature that lowers the frequency of filter changes.

Durability. All working parts are totally enclosed and protected from dirt, water and impurities. Each moving part is self-lubricated at all times by the fluid in the reservoir.
