Progressive Lubrication Systems
Bijur Delimon International series progressive lubrication systems are generally used on medium-duty machinery and equipment. Robust pumps are connected to divider valves, some of which are modular, allowing for easy installation, modification and maintenance, without the removal of any tubing.
The series M2500G, 3000 and PVBM Progressive Divider Valve Manifolds distribute and proportion incoming oil or grease to bearing points. A typical divider valve manifold consists of an inlet section, three to ten valves, and an end section. One assembly can serve up to a maximum of 20 lubrication points. Individual divider valve blocks have a discharge piston and built-in outlet check valves. Blocks are offered in various output sizes. The discharge capacity of a block is determined by varying the piston diameter in the valve block.
Twin valve blocks have two outlets located at each end of the assembly and supply rated discharge from each of the two outlets during one complete valve cycle. Single outlet blocks have one end outlet plugged and supply twice the rated output to the open outlet. External cross porting of adjacent valves can be achieved with a cross port kit to combine outputs.
Progressive Divider Valve Operating Sequence
Individual valve blocks operate in a “Progressive” sequence. During operation, the piston within the block must complete a full discharge cycle before another piston begins operation. As long as lubricant is supplied under pressure to the inlet section of the divider, manifold valve blocks will continue to operate in a progressive manner.
When lubricant flow is interrupted to the inlet block, piston movement stops. When flow resumes, piston movement commences at the same point in the discharge cycle. Feed lines deliver lubricant from the valve block to individual lube points. Should a discharge line become blocked, it will stop all the valves operating. Indicators are available to alert a blockage.
