This pump includes a computing device, with a vibration waveform analysis section and a memory, the analysis section being designed to control the motor, by comparing a vibration waveform received from the vibration sensor with vibration waveforms saved in the memory.

Pump with vibration sensor and its production process

A wastewater pump for conveying solids-laden wastewater includes a spiral housing with an inlet opening, an impeller with at least one vane having a leading edge running from the impeller hub in a backwardly curved manner, and at least one finger for wiping off contaminants from the leading edge. The at least one finger is arranged on the inlet inner wall and extends in the direction of the impeller rotational axis. At least one groove is present in a suction-side inner wall of the housing to receive and convey material that is removed by the at least one finger from the leading edge to. The leading edge of the impeller and the surface of the at least one finger which faces toward the leading edge are at an angle of 5° to 75° with respect to the rotational axis.

Wiping element for impeller leading edges of wastewater pumps

In this pump, the angle between the imaginary tangent plane to the lip and passing through the axis and an imaginary straight line, perpendicular to the axis and passing through the point furthest from the axis of intersection of the upper surface of a finger with the lateral leading surface of this finger, is between 110 and 140&#xb0;.
