The pump is based on the second generation of pumps on the basis of innovation, with the characteristics of the second generation of pumps.
Characteristic：
A, design innovation: Rotor line optimization design, the key is not the structure optimization, material configuration is more reasonable.
B, process innovation: the key components of the use of metal mold casting, resin sand molding, digital processing, the appearance of no putty paint.
C, better performance: zero flow compression ratio, high vacuum limit, high reliability.
D, shape innovation: to increase the effect of heat dissipation design, beautiful appearance, has applied for design patents.
