Integrated motor pump

The utility model relates to an integrated motor pump, which transmits coaxially and is good in reliability and small in occupied space. The integrated motor pump comprises a motor, a motor end cover is arranged at the front end of the motor, a guiding groove with a spline is arranged inside a motor shaft inside the motor, a gear pump is arranged in the front of the motor, the spline is arranged on a shaft of the gear pump, and a spline shaft on the gear pump is closely connected with the spline in the guiding groove of the motor. The gear pump is fixedly connected with the motor end cover through a bolt. The integrated motor pump has the advantages that the gear pump and the motor end cover are fixedly connected together through the bolt, the motor shaft and the gear pump shaft share the same coaxiality and transmit coaxially, transmission precision is guaranteed, and reliability is good.
