These lubricators can be fitted with up to three independent piston elements providing positive displacement output to series progressive divider valves. TTN Progressive Lubricators are available with an integral programmable controller, low level switch and various reservoir capacities. Operating voltages are 12 or 24 VDC. Suited for off-road mobile machinery, these lubricators feature a unique reservoir design to keep out contamination and prevent condensation from forming.
