NOVELTY - The pump has a magnetic tent provided with a permanent magnet part that is provided with a pole head. An iron core-coil is arranged in the magnetic tent that is fixed in a radial magnetic part. A rotating shaft is arranged in the permanent magnet part that is connected with a machine body. The magnetic tent is coated with boron by a multi-layer graphene sheet. The coil is wounded through a graphene lead. USE - Iron core motor corrosion resistant pump. ADVANTAGE - The pump can improve working efficiency, and a core part of a motor is connected with a machine that is made of non-metal material, and utilizes power device in chemical industry for conveying concentration of acidic, oils and toxic liquid, and reduces volatile corrosion in resistant pumps.
