A combined pump and valve apparatus including a cylindrical casing, a shaft arranged symmetrically in the casing, a device fixedly attached to the shaft and in close fit with the cylindrical casing, thereby defining separated chambers within the casing, a plurality of outlets/inlets arranged along the circumference of the casing, and a plurality of axially arranged inlets/outlets, each of which is fixedly connected to a respective one of the separated chambers. The axially arranged inlets/outlets are alternately in fluid connection with each of the outlets/inlets fixedly arranged along the circumference of the casing in response to rotation of the shaft and the device with respect to the casing. An impeller arrangement pumps a fluid through the combined pump and valve apparatus in response to the rotation of the shaft.
