How It Works
When power is supplied to the motor (via either an on-board timer on controller or by customer-supplied power) the motor runs the gear pump. As the motor turns, the gear pump pulls lubricant in from the reservoir and delivers pressurized lubricant to the distribution network via the outlet(s) in the top plate. Pressurizing the distribution network forces all the resistance fittings in the system to open, allowing lubricant to flow to the friction points. The resistances fittings continue to flow and the pump builds pressure until pressure relief valve setting is reached (75psi). Once the motor is shut off, pressure in the distribution network returns to near 0psi. This actuates a quick dump valve which relieves the line pressure back into the reservoir.
