Magnetic drive pumps with magnetic drive spiral structure, and ensure that pumps can be an absolute seal, leak-free transfer to corrosion, flammable, explosive, toxic and other chemical mediator.

Features:
1. High head, low flow rate than the mass number is less than 40.
2. The simple structure, small size, light weight.
3. Has a self-lubricating circuit, to improve life of sliding bearings.
4. The addition of the cooling circuit, magnetic eddy heat away in time.
5. The use of cantilever blades, impeller radial force reduction.
6. With the annual increase in transport medium, the pump efficiency is drastically reduced, making up no more than the year of 5 * 10m3/s.
