Mono-material divider block assembly

A divider block assembly for distributing a low volume of a lubricant at high pressure, the divider block being operated by the pressure of the lubricant being dispensed, comprising:

• one divider block made from a single integral and gaples sly continuous piece of material having;
• a single inlet, at least three outlets, at least three piston bores, each piston bore sized to receive a replaceable sleeve, for each piston bore, a replaceable sleeve with an outlet passage for lubricant, a single piston in each of the replaceable sleeves, the single piston dispensing lubricant by the pressure of the incoming lubricant multiple seals between each of the replaceable sleeves and the corresponding piston bore, the multiple seals separating hydraulic circuits within the diver block assembly, the piston sequentially opening and closing hydraulic circuits as the pistons move in the corresponding replaceable sleeve, such that lubrication is dispensed sequentially from each of the three outlet passages without check valves in the divider block;
• and
• at least one end plug that is aligned with the replaceable sleeve.
