The approach presented here concerns a pump for delivering a fluid. The pump comprises an impeller, a drive device with a shaft, a shaft housing and a sealing device. The impeller is shaped to deliver the fluid. The drive device with the shaft is designed to drive the impeller. The shaft housing is shaped to receive the shaft and/or the drive device. The sealing device comprises at least one casing sealing element and/or an impeller sealing element which is received between the drive device and the impeller and which is designed to prevent fluid from entering the drive device and/or the shaft casing during operation of the pump.
