Abstract: A pump housing has a spiral housing and includes a suction channel (14) which runs out in a space (15). The space (15) is for arranging an impeller (6), rotatable about a rotation axis (5), and includes a spirally peripheral channel (16) open to the space (15) and running out into a pressure channel. A receiver (20) for a differential pressure sensor is provided within the pump housing. A first sensor channel (22) is provided, which connects the receiver (20) to a pressure-side interior of the pump housing. A second sensor channel (23) connects the receiver (20) to the pressure-side interior of the pump housing. The receiver (20) for the differential pressure sensor is arranged between the spirally peripheral channel (16) and the suction channel (14), so that the channels can be formed by way of simple bores.
