Zhengzhou Brocade produced circulating water pump is circulating water as the working fluid, utilizing a novel multi-jet vacuum pump to produce a negative pressure design principles, to provide vacuum conditions for chemical laboratory people, and can provide cooling water to the reaction apparatus. Widely used in evaporation, distillation, crystallization, filtration, vacuum, biochemical and other operations, is the ideal device universities, pharmaceutical chemicals, food processing and other areas of the laboratory. Zhengzhou Brocade production of recycled water is to use a water jet pump to create a vacuum principle production laboratory vacuum generating device in different laboratories of the title, the other name for the following categories: circulating water pumps, circulating water multi-purpose vacuum pumps, vacuum pumps and water ring vacuum pump. Zhengzhou Brocade desktop circulating water pump each containing a circulating water pump, giving high quality rubber tube two meters, fuses two, three to two. Circulating water pump classification: Zhengzhou Brocade produced by circulating water pump model is divided into different desktop circulating water pump SHZ-D (Ⅲ) type, vertical high-power multi-purpose water circulating pump SHZ-95 type. Zhengzhou Brocade circulating water pump in accordance with the movement and the pump head can be divided into standard anti-corrosion materials, PTFE based material type, stainless steel type. General laboratory use are double-double pumping vacuum table, there is a special type four table four drawers: four vacuum table, four taps, this type of pump may also have four students to experiment, to a large extent Experiments on the narrow space, you need to be customized in advance.
