ABSTRACT:
A device for controlling the pressure at shaft-sealing parts of an apparatus, wherein pressure equal to an external pressure around the apparatus is established in an interconnect chamber as well as in a motor chamber so as to equalize pressures applied on the shaft-sealing parts disposed between an impeller chamber and the interconnect chamber and between the interconnect chamber and the motor chamber. Due to the above, the apparatus can eliminate any damages which may occur in the shaft-sealing parts of a conventional apparatus used in a pressurized atmosphere.
