The hydraulic suspension pump’s body is made up of the motor shell, the pump body, junction box components, and a sealing ring. The entire pump’s protection level can reach IP67.The rotor, hollow shaft, impeller, and wear-resistant sleeve—which turns into a revolving component—make up the oil pump’s interior portion. At either end of the hollow shaft, two hydraulic suspension mechanisms are installed for support and bearing. With a lead wire connected to the junction box and the outside power and ground wires, the stator windings are attached between the rotor and the motor shell. The hollow construction is used on the oil pump motor shaft to improve hydraulic suspension lubrication and heat dissipation.
