Investing in innovation is about empowering impressive and
revolutionary ideas. Such as the one embraced by Continuum,
a new pumps with continuous intermeshing, no-leaking rotors. |
|
HIGH PRESSURE, LOW NOISE AND LOW PULSATION |
The Continuum® concept is based on three patented breakthroughs: |
| - the rotors profile; |
- the screw step; |
| - the inner force balancing. |
|
PRESSURE RIPPLE AND NOISE ANALYSIS |
The present structure of high pressure gear pumps typically implies
rooms of compressed fluid between gear teeth. |
As consequence: |
- sharp changes in pressure growth |
- noise (starting from 1.500 rpm) |
The continuum design concept achieves one main design objective: |
- Total absence of high pressure rooms of compressed oil between gears; |
- No trade-offs on material selection and treatments. |
The above implies: |
- smooth changes in the pressure growth |
- HIGH Performances |
- LOW noise (up to 5.000 rpm) |
| The pressure ripple laboratory test shows the impressive improvement of the pulsation in a |
| Continuum® designed pump (pressure sampling at 100 KHz) while maintaining excellent |
efficiency. |
