design of Bredel heavy-duty hose pumps combines the small footprint of close-coupled pumps with the reliability and simplicity of long-coupled pumps.
All models are based on a proprietary, all-digital, power-conversion technology platform that supports a set of formerly unavailable features and capabilities used in programmable power sources, including a direct-coupled
output that allows for AC output, DC output, or AC+DC combined output modes.

The pumps comprise two FMI valveless pump heads direct-coupled
to a single variable speed drive, standardly a 23 frame stepper motor, although other drive types can be used.

At the heart of the machine is Alpine's patented X-Die.On each of the five extruders, the screw is direct-coupled
with the drive shaft of a two-stage gearbox and is turned by a water-cooled, asynchronous AC motor.
"OEMs tasked with designing a highly optimised and tightly integrated machine or device will find KBM motors to be an excellent choice due to their unique design which inherently improves mechanical compliance, reduces parts count and improves performance through the use of powerful direct-coupled
electro-magnetics with a light weight and compact form factor," the company said.
The machine, built on a single-piece cast machine bed, includes direct-coupled
digital drives, which help deliver rapid traverse rates up to 60 m/min and acceleration up to 6 m/s sq.
