Rotating machines
Electrically driven high-speed pumps for low-viscosity fluids use gas-lubricated drives to combine low-friction advantages with hermetic sealing and integrated centrifugal pumps, creating a maintenance-free system. These pumps excel in critical applications, including radioactive environments, toxic substance processing, ultra-clean conditions, and high-reliability, long-lasting usage scenarios.
Electric pumps are a big step forward for rocket engines. They simplify the propulsion control system and enable accurate thrust direction and intensity adjustments over a large spectrum, ensuring precise and safe maneuvers in space missions. So is achieved the safe return of astronauts or valuable samples to Earth or the accurate delivery of the payload of rocket carriers at their destination. E-pump reliability, efficiency, and compact design make them invaluable components, reducing the risk of system failures and optimizing spacecraft performance.
