A peristaltic pump 2 comprising: a housing 10 having a hub 18; a rotor 12 disposed within the housing 10 and rotatably supported by the hub 18, the rotor 12 comprising a drive shaft 16 which extends through the hub 18, the drive shaft 16 configured to engage with an output shaft 8 of a drive unit 4 to form a drive connection; wherein a first misalignment pivot 32 is formed between the rotor 12 and the hub 18 and a second misalignment pivot 34 is formed between the drive shaft 16 and the output shaft 8 of the drive unit 4. The first misalignment pivot 32 may be formed by a bearing 20, eg a single spherical roller bearing, between an outer surface of the drive shaft 16 and an inner surface of the hub 18, or between the hub 18 and the rotor 12. The second misalignment pivot 34 may be formed by an eg splined drive connection formed by a converter sleeve 28 attached to output drive shaft 8 and a female receiving portion 26 in the hollow driveshaft 16. |
