MultiPort II Lubricator - PDI

MultiPort II Lubricator - PDI


The MultiPort II Lubricator is an electrically driven multiple outlet lubrication unit designed primarily for use with positive displacement injector(PDI) systems. The pump has two combined pumping elements at the left and center positions, with a PDI kit at the left position and a return at the right

position. Pump outlet is located at the left for direct feed to the injectors. These lubricators are available with 12 & 24 VDC motors which make them ideal for use in mobile applications. An integral controller is available, or the pump can be controlled by an external controller (such as SMDC) or by the customer's PLC/DCS/etc.


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 discharged

through 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.


  • Compact rugged design
  • Minimal maintenance required
  • High and low pressure capabilities
  • Rotating mixing arm in reservoir assures grease delivery to inlet of pump element
