Liquid Color Pumps

Maguire's proprietary technology has contributed to being the world's largest supplier of liquid color pumps. For all molding and extrusion applications Accurate peristaltic dosing Easy to set up

Liquid Color Applications

Maguire's MS4 PeriStep pump provides precise metering at low rates to improve the quality of the coloring process.

Self Adjusting Speeds

The pump design and control makes it versatile for all types of molding and extrusion processes.

Wide Range of Dosing Outputs

The choice of three tube sizes allows for wide range of dosing outputs- greater flexibility for the user.

Control Modes

Extrusion - Continuous Mode: the MS4 will run the pump continuously at a rate set by the operator.
Extrusion - Extrusion Following: the speed will change depending on throughput to maintain the correct percentage color dosed.
Molding - Cycle Mode: the MS4 provides accurate dosing, regardless of variations in the process by monitoring the screw back time of the injection molding machine.
