Abstract (en)
Satellite pump whose body is divided into at least two parts constituting bodies, characterized in that, in the rear body (3) there is a suction duct (KS) placed coaxially with the rear body (3), at least two inner ducts (KW) routed throughout the whole length of the rear body (3) and ring duct (KP) routed in the rear body (3) adjacent to the rear compensation plate (6) and coaxially with the shaft (7). The invention also comprises a ring-shaped compensation chamber (KK) which is adjacent to the rear compensation plate, while the suction duct's (KS) has diameter not larger than the inner diameter of the central body (2) both in the case when the front body (1) and the central body (2) constitute one part, and in the case when the front body (1) and the central body (2) constitute two separate parts and moreover. The inner ducts (KW) connect the suction duct (KS) with the ring duct (KP) and the ring duct (KP) is connected with the suction holes routed in the rear compensation plate (6).
