Providing the long service life for low water/low gas consumption pumps

The wide use of low water/low gas consumption pumps does not allow their distinct classification based on their use in the SC TCS of any kind. They may be used for both - very long life service which amounts to years and for the short-term period of several minutes. Long life operation assumes the accurate balancing. The choice and the balancing of the pump are determined by the parameters of the system in which they will perform their functions. The main function is to ensure the supply of the propellant with specified flow rate and pressure, not causing microvibrations which have acceleration of g >10-2
