MS4 PeriStep Pump

Intelligent Simplicity The MS4 patented Maguire peristaltic pumps are designed to accurately meter precise amounts of liquid color into the main flow of natural material directly for both molding and extrusion applications. Positive displacement pump Series MS4 PeriStep pumps are liquid color pumps, with no seals, check valves or clearances to allow even the slightest internal leakage. The units are self-priming. Automatic speed control The MS4 control software uses automatic speed control to assure self-adjusting accuracy. The pump design and control makes it versatile for all types of process including injection and blow molding, and extrusion applications. Three tubing sizes available Three tube diameters and assemblies are available to provide a wider range of dosing outputs. Ideal for liquid color applications Maguire's MS4 PeriStep pumps provide precise metering at low rates to improve the quality of the coloring process. Easy maintenance The pump design is compact and lends itself to minimal maintenance. Liquid delivery tubes are quick and easy to change when color changes are required and can be re-used, requiring replacement periodically according to usage and time. Typical tube life is 1 to 6 months. Robust design The compression rollers are solid rollers, so they never lose their tube compression tolerance, which can otherwise impact on dosing consistency and accuracy. As there are no bearings to wear out, production can keep running. Easy disassembly In the unlikely event of needing to disassemble the pump, the Split Head access is easy - the cover detaches by releasing 3 screws and the complete roller set can be removed from there. Run modes The MS4 is capable of running in Continuous Mode, Injection Molding (Cycle Mode) and Extrusion Following Mode. In Continuous Mode, the MS4 will run the pump continuously at a rate set by the user. In Cycle Mode, the MS4 provides accurate dosing, regardless of variations in the process, by monitoring the screw back time of the injection molding machine. While in Extrusion Following Mode, the speed will change depending on throughput to maintain the correct percentage of color dosed.

Four Roller PeriStep Drive System The new MS4 pump uses a “Sun and Planetary” design to drive the rollers. The precision stepper motor drives a central “sun” drive roller, which creates friction when pressed against the outer “planetary” rollers. The four outer planetary rollers are held in place by a cage to keep them positioned uniformly around the central drive roller to ensure accurate and precise peristaltic dosing of liquid. Stepper motor The patented design of the pump (Patent App #: 62/025), utilizes a stepper motor with no gearbox to drive the dosing of the liquid and provides an...
