How It Works
As the motorized gear pump pulls lubricant in from the reservoir and delivers lubricant to the distribution system, the PDIs in the system discharge a fixed amount of lubricant to the lubrication points. After the injectors are fired, the pressure in the network continues to rise until the limit in the pressure switch is reached. Once the limit is reached, the pressure switch signals the motor to stop. When the momentary pressure in the distribution network becomes greater than the gear pump pressure, the pressure differential actuates a quick release valve which relieves the distribution line pressure back into the reservoir. This causes each PDI in the distribution network to reset and refill for the next cycle.
