The circulating water-type multi-purpose vacuum pump series uses circulating water as the working fluid and uses fluid jets to generate negative pressure for injection.

It provides vacuum conditions for evaporation, distillation, crystallization, drying, sublimation, filtration and decompression, and degassing processes. It is especially suitable for laboratories and small tests in colleges and universities, scientific research institutes, chemicals, pharmaceuticals, biochemistry, food, pesticides, agricultural engineering, bioengineering and other industries.

●Recycle water to save valuable water resources.     ...

●Save more than 35% of electricity than other types of vacuum pumps. ....

●Specially made fluid muffler reduces water gas and makes the vacuum more stable； Reduce gas-liquid friction and reduce noise. ...

●Double-tap and dual-meter display can be used individually or in parallel.

●Resistant to acid, alkali and solvent corrosion.

●Special motors are made by well-known motor manufacturers ODM， Fluoroelastomer seal, no corrosive gases in the motor are invaded.

▲The water in the sink needs to be replaced regularly to ensure the water quality is pure, the vacuum degree is guaranteed, and the stains are avoided.

▲It can be used to extract corrosive gases and needs to shorten the water change cycle.

◆SHB-Ⅲ：The shell, sink, jet, tee, check valve, and air extraction nozzle are PP Material； The pump body and impeller (six-channel, double seal) are pressed by stainless steel plates, and the material is in line with ANSI standard.

◆SHB-ⅢA： The jet and air extraction nozzle are made of stainless steel ( ANSI Standard), other SHB-Ⅲ。

◆SHB-ⅢS： The pump body is PP Material, more suitable for acid gases, other SHB-Ⅲ。

◆SHB-ⅢT： Transparent sink, easy to observe water level and water quality, the same SHB-ⅢA。
