As, however, the first pump bearing (6) is secured to the end plate (21) before the electric motor is fitted, it is proposed that the holder have a clearance A such that the first pump bearing is unlosably secured to the end plate (21) before assembly.

The pump housing has a pump bearing (19).

A bearing assembly, a pump with a bearing assembly and a method of lubricating a pump bearing using a bearing assembly.

The invention concerns a vertical centrifugal pump comprising a support bearing, arranged above the pump and consisting of an axial bearing (22) and a radial bearing (23).

The electrodynamic bearing supports the impeller either axially or radially during operation of the pump.

The pump chambers are arranged between the fixed bearing and the free bearing.

The outlet side of the pump (201) is hydraulically coupled to the further pump (210) in order to lubricate the crank bearing (214) and the further crank bearing (215) with the fluid.

A bearing plate (10), which carries a pump-side bearing for the rotor (4), is also provided, wherein the bearing plate (19) is fixed on the housing side and in the area of the pump-side bearing protrudes into the motor can.

In normal operation, the forces which act on the pump eccentric (18) are essentially supported by the main bearing (15) and by the pump bearing (19).

A bearing (14) is disposed between the oil pump drive shaft (18) and the bearing fixing plate (19).

After assembly, i.e. when the first pump bearing is inserted into the corresponding recess in the pump housing (3), the end plate can be sufficiently moved to align the bearing with the pump bearing (6).

The sealing assembly is interposed between the thrust bearing and a primary pump of the electric submersible pump.

The Roots pump further has a bearing holder installed on the bearing and fixed to the lower housing member.

The invention relates to a blood pump comprising a rotor mounted over a bearing in a pump housing.

The temperature transmitting collar (81) is mounted on the pump line shaft (40) immediately adjacent to the stretch bearing (61), which is the top bearing in the pump system.
