Overview

The Vibration Compressor is the flagship invention in the Nemesys portfolio — built around a simple but unconventional idea: use controlled vibration and centrifugal force to drive reciprocating work efficiently. Instead of relying on classic motor-crank architectures, the system transfers force from an eccentric weight mechanism through linkages to opposed pistons, enabling compression or pumping with a strong focus on improved energy balance. Prototype measurements and published benchmarks indicate significant efficiency potential, and the concept has been publicly presented and moved into industrial manufacturing collaboration.

How the Vibration Compressor Works

Eccentric weights generate controlled force as they rotate, creating a usable centrifugal effect.
Linkages transfer the motion into a stable reciprocating drive.
Opposed pistons perform compression/pumping cycles in cylinders.
Output can be regulated by adjusting the eccentric setup and operating speed for different loads.

What did the Slovak Metrology Institute measure?

Same motor. Same conditions. Documented protocol results.

The measurements were carried out by the Slovak Metrology Institute in the laboratories of the University of Žilina on 5 December 2024, based on a cooperation memorandum. Two pumps were compared under the same conditions — identical electric motor (270 W), identical hoses (2 m, inner diameter 12 mm), the same pressure (0.5 bar) and comparable flow rate (~17.5 l/min).

	Serial pump (Sigma)	Nemesys vibration pump
No load:	189,9 W	197 W
Under load (~17.5 l/min, 0.5 bar):	304 W	119,6 W

Under load, the power input of the serial pump increased, while the power input of the vibration pump decreased. The University of Žilina described this difference as significant and stated that it indicates higher efficiency.

The vibration pump is driven by a vibration motor with rotating eccentric weights. The motion is transferred to the pumping section, which moves the liquid — a similar role is performed by a piston or membrane in conventional pumps, but the excitation principle is different.

The inventor, Pavol Nemeš, attributes the saving to the use of the effects of centrifugal force. This interpretation is subject to further technical and scientific examination. What is documented, however, are the measured values shown above.
