1. A pump array, comprising an accommodating housing which forms an accommodating space with an end-facing wall and a circumferential wall and a pump insert, which is at least partially arranged in the accommodating space, the pump insert comprising:
a pump comprising a pump chamber and a delivery element which is rotatable about a rotational axis and which is arranged in the pump chamber;
an electric motor comprising a rotor, which is rotatable about the rotational axis, and a stator;
a drive shaft which is mounted such that it is rotatable about the rotational axis, wherein the rotor and the delivery element are connected via the drive shaft in such a way that rotating the rotor causes the delivery element to rotate; and
an inlet, which is embodied to feed fluid to the pump chamber, and/or an outlet, which is adapted to discharge fluid from the pump chamber, on the side pointing towards the end-facing wall of the accommodating space,
wherein the end-facing wall of the accommodating housing comprises a feed channel and a drainage channel; and
wherein the pump array further comprises a tubular connecting element, which is adapted to be inserted into the feed channel from the side of the accommodating space and which is inserted into the inlet and arranged between the feed channel and the inlet and connects them in fluid communication, and a tubular connecting element, which is adapted to be inserted into the drainage channel from the side of the accommodating space and which is inserted into the outlet and arranged between the drainage channel and the outlet and connects them in fluid communication.
