1 45 P rogressive systems can be used for oil or grease lubrication when it is required to provide a positive displacement with visual or electrical monitoring. ll outlets can be checked by one indicator rod or electrical switch. range of automatic control timers and monitors are available.

2 46 escription centralized lubrication system is described as when it contains metering pistons, which can operate in a sequence thereby giving measured amounts of lubricant to each lubrication point. s each piston in a distribution block is moved it opens the passageway for the following piston which can therefore distribute pre-determined amounts. ach lubrication point receives a measured amount of lubricant and this can normally be varied by changing the values of the individual metering screws. s each metering piston is put in series with all the other pistons, any blockage to the lubrication point results in the whole system being stalled. This stalling of the system enables the operator to visually check the system, or else micro switches can be fitted to enable the checking process to take place automatically. range of programme controllers is available for this purpose. Lubricants: Oils up to 2000 cst/40 and greases up to grade 2 (NLGI) Typical system layout using Pneumatic Pump for grease - with monitoring Typical system

3 47 istributors Monoblock Type Operating sequence 1. In (), supply pressure through internal passages moves piston 3 left, while pistons 1 and 2 are positioned to the left. 2. In (), piston 3 bottoms, it opens internal passages directing supply pressure to the left end of piston 1. Lube discharges from port In () piston 1 bottoms. It opens internal passages directing supply pressure to the left end of piston 2 which returns to its initial position as lube discharges from port The sequence continues, positioning the piston 3 to the right and the piston 1 to the left. Lube discharges from port 4, then 6. Modular Type The main feature of this series is that the upper section of the distributor, which contains all of the working parts, is detachable from the lower part which is fixed to the machine and accommodates all of the pipe connections. This design allows all the inlet and outlet pipework to be installed with the knowledge that it will remain undisturbed in the event of a metering section requiring replacement. It requires only the removal of 4 screws to detach the metering section of the distributor.
