This pump is based on laboratory area, designed a new type circulating water pump, its functions and uses of the same B type pump, a host of stainless steel material. With external circulation device, vacuum stability, beautiful appearance, little and dainty unique unique.

( 1) the machine adopts double-tap, can be used alone or in parallel, with two tables;

( 2) master the use of stainless steel plate stamping, exquisite appearance, for special engineering plastic box;

( 3) equipped with a specially designed muffler fluid, reduce the gas and liquid water friction noise, so that higher and more stable vacuum. Corrosion resistance, no pollution, low noise, easy to move, can also be based on user needs to install a vacuum valve, easy to operate;

( 4) SHZ-D (Ⅲ) anticorrosive multi-usage vacuum pump with water circulation, performance and SHB- Ⅲmulti-usage vacuum pump with water circulation performance of the same, the same appearance; but the main parts of the jet, three, check valve, such as exhaust Tsui all the important components and anti-corrosion stainless steel specialty plastics material two, containing acetone, ethyl ether, on other chloro-organic chemicals Fang operation, has the corrosion resistance to dissolution.

( 5) storage tank using newly developed special plastic material, containing acetone, ethyl ether, other chloro-organic chemicals Fang operation, has the corrosion resistance to dissolution.
