Peristaltic Pumps
78% lighter weight, more efficient and more compact.
Application
Peristaltic pumps are a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained within a flexible tube fitted inside a circular pump housing. A rotor with a number of rollers compresses the flexible tube. As the rotor turns, the part of the tube under compression is pinched closed thus forcing the fluid to move through the tube.
Customer Goals
Peristaltic pumps require relatively high torque at low rotational speeds, typically in the range of 5 to 500 RPM, well below the direct drive capability for conventional AC or DC motors. As a result, conventional motors are operated at a higher speed (over 1000 rpm) and a speed reduction gearbox is necessary to achieve the required torque and rotational speed. These geared drive systems are large, heavy, inefficient and the gearbox increases cost while causing a reliability and maintenance burden.
Key Problems Solved by ETM Technology
- Lighter, Compact & Quieter
Eliminated the need for a gearbox, reducing weight by 78% and overall length of power train from 16 in (400mm) in length to 6 in (150mm). - Higher Efficiency
Compared to the AC geared system, power consumption is reduced 29-54% for the ETM direct drive system. - Increased Operating Range
ETM Direct Drive systems operate at higher continuous loads compared to much larger, heavier AC geared systems. - Improved Reliability & Maintenance
ETM Direct Drive Systems have a single moving part, the motor rotor, which enables greater reliability, reduced maintenance and reduced noise.
