WORKING PROCEDURE
Pumping station, piping, does feeders, end pressure reducing valve are fitted as per decided scheme and the items are connected with control panel. When pump is started grease shall be delivered to first main line and it will finally reach to connected lubricating points through does feeder. Once grease is delivered to all points pressure in line starts rising as pump is still supplying grease. As soon as pressure crosses set pressure value, pressure reversing value, through control panel actuates. Grease starts flowing into second line. Delivery of grease to lubricating points takes place and pressure rises again. When it crosses set pr. of end relay, system stops. Cycles is over and all points are lubricated. Now after preset 'OFF' time, system starts again and repeats above sequence.

PNEUMATICALLY DRIVEN PUMPS
These pumps powered by second pneumatic motor are normally provided with an overpressure line reversing value. They are to supply grease at a pressure of 150 bar to the discharge capacity of 200 to 600 gm/minute at air pressure of 4-7 bar. There is a provision for grease level sensing. The special line reversing level is settable from 30 to 150 bars by an adjustable screw.

The motor pumps ratio is 30:1. For filling grease into reservoir inlet port is provided at the bottom. Pump has reservoir capacity of 5 ltr. Cycle of the pump is governed by separate electrical/electronic control.
