Compact, easy to use & setup, with quick liquid color changes
Highly efficient planetary roller drive design
Stepper motor with no gearbox for precision control
Easy for operators to use
Three Steps to Easy Operation
The control requires only 3 inputs for an operator to setup and start using
the MS4 pump. The design is simple and intuitive and avoids complex or menu
driven interfaces that can be slow or complicated to set and start production.
The simple 3-step process is:
1. Set SHOT WEIGHT (part GRAM weight), or extrusion rate (process kg/hr or lb/hr)
2. Set LIQUID COLOR PERCENTAGE, (% of part weight)
3. Set DENSITY of the Liquid Color, (lb/gal or kg/ltr)
Simpler entry of variables
It's easy as 1,2, 3. With these 3 values entered the MS4 control
automatically calculates the rest, working out the desired weight to volume to
dose - again simplifying operator interface, setup time and minimizing
opportunity for error.
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.
The new 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
extensive range on the dosing control and capacity.
The dosing range is fully maximized by the intelligent technology of the
software control combined with the central roller driving an outer set of
rollers through friction contact, providing a 5 to 1 speed reduction without a
gearbox, ensuring accurate dosing, an efficient and compact design, minimal
on-going maintenance, plus still allowing speed of access and color change for
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
Automatic Speed Control
The MS4 control software use 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 further range
of dosing outputs.
Ideal for Liquid Color Applications
Maguire MS4 PeriStep pumps are best suited for accurate metering at low rates
typical of liquid color applications.
Easy Maintenance & Cleaning
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.
There are no bearings to wear out. The compression rollers are solid rollers, so they never loose their tube
compression tolerance, which can otherwise impact on dosing consistency and
accuracy. In the unlikely event of needing to dis-assemble the pump Split Head
access is easy - the cover removes by releasing 3 screws and the complete roller
set can be removed from there.
Lock & Load
"Easy Load" & "Safety Lock" design functionality.
After a color change the "Easy Load" design of the MS4 pumps allows a new
color tube to be positioned quickly and easily. The tube is simply laid over the
top of the rollers without the need to work the tube into a compression zone.
User Safety is key in the design of the Maguire PeriStep Pump utilizing a
safety interlock when accessing the pump drive assembly. The MS4 pump uses a
"Split Head" design. When the split head is released it provides a 12.7mm (1/2")
access, exposing the top surface of the roller set. The drive motor is
safety-interlocked to ensure the motor cannot run when the top half of the pump
head is raised / open, and the drive rollers are accessible. The design makes
sure the rollers cannot run whilst tubes are removed or inserted. The MS4
PeriStep pump is safer, with no user access to rotating parts.
