Controller for use in single-line lubrication systems

84501

Model 84051 program timer is used to control the lubrication cycle frequency of air-operated, single-stroke pumps. The timer turns pump on/off at programmed intervals via a 3-way or 4-way air solenoid valve (not included) installed in the air line to the pump. It is capable of retaining memory for three hours during machine shut down or power failure. Timing is suspended during power interruptions. This feature eliminates over-lubrication due to pre-lube when machine is frequently started and stopped. Using two programmable jumper pins, four options are available with the memory and prelube feature.

Features and benefits:
  • Program timer controls lubrication cycle frequency of air-operated, single-stroke pumps
  • Timer turns pump on/off via solenoid air valves in programmed intervals
  • Retains memory for three hours during machine shut down or power interruption
  • Suspended timing during power interruptions eliminates over-lubrication due to pre-lube when machine is frequently started and stopped
