Progressive Lubrication Services


The Series Progressive system pumps oil or grease in either a cyclical (total loss) or continuous (recirculative) manner.

Engineered to positively deliver an exact displaced amount of lubricant to every single bearing point, the divider block design is capable of operating in severe environments and accommodating upwards of 200 delivery points in a single pump system.

How It Works

A lubricant pump is connected to an engineered network of series progressive divider blocks, and via a controller is allowed to pump lubricant in a continuous or controlled cyclical systematic manner to each divider block.

A divider block, which is built in a modular style, contains a series of lapped, hydraulically actuated spool valves sized for varying displacements. The valves are progressively linked together in series, causing them to “shuttle” over to one side of the block in a progressive pattern, then to “shuttle” back to their original positions as the lubricant continues to be pumped through the block. Because of its hydraulic nature, as a valve is shuttled back and forth, it displaces a lubricant charge on one end of the valve to the bearing point, while simultaneously filling the void on the other side of the valve in preparation for displacement once the valve “shuttles” back. The ability to “cross-port” a valve results in “doubling” the delivery of lubricant on one side of the valve only.


To ensure every point has delivered a charge of lubricant, the first valve in the divider block can be attached to a cycle pin indicator that visually indicates the block has completed one full cycle by moving in and out one time. Attaching a counter/timer control to the cycle pin will indicate if no delivery has taken place within a given time period and signify a broken main delivery line.

Blocked and crimped lines can be visually detected via simple mechanical overpressure indicators connected at the secondary delivery-line block outlet. Whenever “restriction”-caused hydraulic back pressure is sensed, a visual indicator pin “pops” up to indicate the exact line/bearing point requiring maintenance. If no electronic alarm sensors are used, operations and/or maintenance must perform regular visual checks for alarm indications.

The Benefits

  • Deliver trouble-free service for many years, thanks to its engineering and tamper-proof design
  • Replacement parts are relatively inexpensive to purchase, stock and replace
  • The system can even be used with a manual grease gun to deliver an engineered amount of lubricant to each bearing point and be automated later
