In the mud pump, the rotary shaft of the electric motor is extended to the opposite side to the centrifugal pump, penetrates the water seal shaft sealing device, protrudes outside the water seal container, and attaches the impeller portion of the jet pump to the tip. . A mud pump, wherein the impeller is installed in the inlet of the effluent of the jet pump, and a discharge pipe from the impeller of the centrifugal pump is connected to the suction side of the effluent of the jet pump. (2) Claim 1, in which a speed reduction device is interposed on the rotating shaft of the electric motor so that the rotation speed of the impeller of the centrifugal pump is lower than the rotation speed of the impeller of the ejector pump.
Mud pump as described. (3) The mud pump according to claim 2, wherein the speed reduction device is a planetary gear device. (4) The mud pump according to claim 1, wherein the impeller of the centrifugal pump is replaced with an auger blade.
