The invention provides an oil filter coupling magnetic drive pump, relates to an oil filter and solves the technical problem that the existing transmission mode in which an electrical motor drives an oil pump is the traditional coupler transmission featuring poor sealing and loud noise. The oil filter coupling magnetic drive pump comprises the electrical motor and a pump; the electrical motor is provided with a motor shaft, the pump comprises a pump case, a pair of gear rotors meshed with each other and an oil leaker; the invention is characterized in that the motor shaft is provided with an external magnetic rotor, wherein one wheel axle of a gear rotor is coaxial with the motor shaft and provided with an internal magnetic rotor matched with the external magnetic rotor; the oil leaker is provided with an oil inlet channel and an oil outlet channel, the pump case is provided with an accommodation chamber; and the pair of the gear rotors are located in the accommodation chamber and divide the accommodation chamber into a suction chamber and a discharge chamber. In the invention, the dynamic seal according to the coupler transmission mode is transformed into closed static seal; and as a result, the leakage of insulating oil is completely avoided, the pump is driven to rotate by a magnetic body, the power dissipation is small, the efficiency is high and the noise is low.
