    Abstract: A circular disc shape case 11 includes a motor rotor chamber 12, a bearing chamber 13 and a gear chamber 14 piled sequentially and being communicated with each other. A suction port 15 is connected to the motor rotor chamber 12, and a discharge port 16 is connected to the gear chamber 14, which communicate with outside respectively. A rotating shaft 18 having an end positioned in the motor rotor chamber 13 and the other end extending to the gear chamber 14. A rotor 22 is fixed around the rotation shaft 18 in the motor rotor chamber 13. A first bearing 19 is provided for supporting the end of the rotating shaft 18 in radial and thrust directions. A second bearing 20 is provided in the bearing chamber 13 for supporting an intermediate portion of the rotating shaft 18 in radial direction. A trochoid gear 25 is provided in the gear chamber 14, having an outer rotor 26 and an inner rotor 27, which functions as a pump, taking in a fluid through the suction port pipe 15, and discharging the fluid from the discharge port 16.

    Abstract: A ferrous cylinder liner for use in diesel engines having exhaust gas recirculation (EGR) is protected from corrosive attack from the EGR environment by first final machining the inner running surface of the liner and thereafter plating the finished inner surface with a thin, non-porous, continuous coating of chromium which serves as a barrier to the EGR gases. The liner is installed and used in its as-coated condition with no post-coating finishing of the coated surface.

    Abstract: A high pressure centrifugal slurry pump in which the impellers and their associated diffusers are formed of hard chrome iron. A liquid-tight high pressure containment shell surrounds the impellers and diffusers and is radially spaced from them. The resulting space between the array of impellers and diffusers and the containment shell is in fluid communication with the interiors of the impellers and diffusers, preferably through a channel located between the last diffuser of the pump and the end wall at the high pressure end of the pumping chamber.
