MultiPort II Lubricator

PDI OPERATION

Power supplied to a motor with gear box drives a precision eccentric cam which engages with the spring load piston elements. This action creates a suction and pressure stroke of the element(s), thereby displacing a fixed volume of lubricant through an outlet check valve. Lubricant is dischargedthrough main line tubing to a series of positive displacement injectors and on to multiple lubrication points. The lubricator also includes a solenoid operated vent valve which relieves mainline pressure when the pump motor stops, allowing injectors to reset for the next cycle.
