Current sealing technology is restricted to whatever speed, pressure and temperature seals can withstand. We are able to push those limits, paving the way for machines that are faster, stronger, smaller and more durable, culminating in a more eco-friendly solution.
The proprierary NextSeal technology balances pressure locally over the seal between the moving parts in a machine. The seal is a critical component in machine performance. The local balancing is achieved through a liquid whose pressure automatically adjusts to the gas pressure throughout the cycle for each of the machine’s revolutions.
Using the NextSeal technology, calculations show us that in the US market alone, a reduction of 29 Megaton of Carbon dioxide equivalents per year of methane gas emitted to the atmosphere is possible. This amount equates to greenhouse gas emissions greater than half the carbon footprint of New York City.
Thereto, the savings would not only have environmental benefits. The gas savings could also be used to power a million households instead of being released straight out into the atmosphere.

A pressure balanced seal makes oil lubrication unnecessary
Reduced friction facilitates higher velocities (RPM counts)
Higher mass flow facilitates 4-8 times smaller machinery
The NextSeal concept works just as well for 10 bar and 1000 bar applications
