PUMPING DEVICE Russian patent published in 2018 - IPC F04D13/02 

FIELD: motors and pumps.

SUBSTANCE: invention relates to pumping device (1), in particular a pumping device with a magnetic clutch, comprising internal space (11) formed by pump body (2) of pump device (1). Contains sealing cup (10) sealingly sealing enclosed chamber (19) in relation to internal space pump (11) formed by body (2). Impeller shaft (20) is rotated about axis (A) of rotation. At one end of impeller shaft (20), inner rotor (24) is installed. Outer rotor (38) interacts with internal rotor (24). Pump device (1) comprises connecting sealing cup (10) with pump body (2) or with a structural member, which is related to pump body (2), in particular body cover (4). Transition element (39) with mounting flange (40) on the proximal to inner space (11) is adjacent to surface (15) of pump body (2), in particular body cover (4). Modular kit for the manufacture of a pump device is also described. It is possible, in a simple way, to adapt the size of the magnetic coupling to various hydraulic parameters by fitting the adapter element in shape and/or size.

EFFECT: pumping device is proposed.
