Flexible for Any Application
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.
Intuitive Operation
Intuitive Design
- The peristaltic pump provides precise metering at low rates, to improve the quality of the coloring process.
- Solid compression roller mean they never lose their tube compression tolerance, so dosing consistency and accuracy is maintained.
- Color changes can be made simply by replacing the feed tube, without the need to stop the process.
Automatic Speed Control
- The MS4 control software uses automatic speed control to ensure self-adjusting accuracy.
- Eliminate need for motor adjustment.
- Versatile for all types of molding and extrusion applications.
- Maximized dosing range – intelligent software provides 5 to 1 speed reduction without the need for a gearbox, providing accurate dosing and greater flexibility.
Simple Startup
Startup – 3 Steps
- Set shot weight (part gram weight), or extrusion rate (process lb/hr or kg/hr).
- Set liquid color percentage.
- Set density of the liquid color (lb/gal or kg/ltr).
The MS4 pump automatically calculates the rest, working out the desired weight to volume to dose, reducing any opportunity for error.
Quick Color Changes
- Liquid delivery tubes are quick and easy to change when color changes are required.
- Liquid color tubes can be re-used and only require replacing periodically according to usage and time.
- Typical tube life is 1 to 6 months.
Rapid Access
- The split head is easy to access – the cover detaches by releasing 3 screws. The complete roller set can be removed from there.
Easy Maintenance
- No seals.
- No check valves.
- No clearances to allow even the slightest internal leakage.
- Self priming pump.
Accurate Peristaltic Dosing
1. Accurately Meter Precise Amounts of Liquid
The MS4 peristaltic pump is designed to accurately meter precise amounts of liquid color.
3. Wide Range of Dosing Outputs
Three tube diameters and assemblies are available to provide a wider range of dosing outputs.
5. Easy Disassembly
In the unlikely event of needing to disassemble the pump, the split head is easy to access by releasing 3 screws. The complete roller set can be removed from there.
2. Suited to All Extrusion & Molding Processes
Accurate dosing into the main flow of material directly for all molding and extrusion processes.
4. Automatic Speed Control
The MS4 control software uses automatic speed control to assure self-adjusting accuracy.
6. Simpler Entry of Variables
Simply enter shot weight, set liquid color percentage, and set density of color. The system automatically calculates the rest.
