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).
- 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
