Key Features

Maguire progressive cavity drum pumps meter colors from 30- or 55-gal. (135- to 230-liter) drums in a smooth, non-pulsating action, achieving pressures of 200 to 300 psi (1380 to 2070 kPa).

Controller 

  • The controller ensures a high degree of metering accuracy by sensing variations in screw movement during the injection molding cycle.
  • Adjust metering rate to maintain uniform color delivery.

Progressive Cavity Pump 

  • The progressive cavity drum pump meters liquid color by positive displacement.

Automatic Speed Control

  • Accuracy is achieved by controlling the exact degree of rotation of the drive motor, delivering precision coloring during each cycle.

Positive Displacement

  • The pump consists of a single helix steel screw (rotor).
  • As the rotor rotates, liquid is drawn into one end, expelling it out the other end, producing a positive displacement pumping action.
