FIELD: machine building.
SUBSTANCE: invention relates to the field of engineering and can be used in peristaltic pumps. Pump 2 comprises: housing 10 and hub 18. Rotor 12 is located inside housing 10 and is supported for rotation by hub 18. Rotor 12 includes drive shaft 16 passing through hub 12. Drive shaft 16 is configured to mate with output shaft 8 of drive 4 for the formation of a kinematic connection. First misalignment center 32 is formed between rotor 12 and hub 18, and the second misalignment center 34 is formed between drive shaft 16 and output shaft 8 of drive 4. Bearing 20 is located between rotor 12 and hub 18 in the same axial position to support rotor 12 with the possibility of its rotation. By means of the bearing the first misalignment center is formed.
EFFECT: problem of conventional pumps, directly linked to the drive, is solved by ensuring that the large misalignment tolerances can be resolved.
