1. This pump adopts shielding set of stainless steel and keep water away from electrical machinery completely,

2. Mechanical seal is not required, thus completely solve pump leaking, adots the high rigidity stainless steel of motor shaft, graphite bearing, water cycle between stator and rotor,

3. Not only for cooling, also can be used for bearing lubrication,

4. Completely solved the noise problem in working. 5. Advanced scientific design, Normal continuous use for 30, 000 hours Trouble-free and maintenance-free. Built-in automatic switch, install and use are more convenient.
