The pump body is made of metal shell lined with fluoroplastics, and the flow-passing parts are all made of fluoroplastic alloys. The pump cover and impeller are all sintered and pressed with metal inserts outsourcing fluoroplastics. The shaft seal adopts an externally mounted advanced bellows mechanical seal.The static ring is made of 99.9% alumina ceramics (or silicon nitride), and the moving ring is made of PTFE filling material, which has excellent corrosion resistance, wear resistance and sealing performance. The inlet and outlet of the pump are reinforced by cast steel body to enhance the pressure resistance of the pump. The actual use shows that the pump has the advantages of corrosion resistance, wear resistance, high temperature resistance, no aging, high mechanical strength, stable operation, advanced and reasonable structure, strict and reliable sealing performance, convenient disassembly and maintenance, and long service life.
Applicable temperature: -50ºC~120ºC. The chemical self-priming pump is an improved and innovative product on the basis of absorbing the advanced experience of related products at home and abroad. It is a replacement product for domestic traditional similar products. The product has the advantages of temperature resistance, pressure resistance, wear resistance, "first drainage, permanent self-priming", etc. The products are made of cast iron, cast steel, stainless steel, reinforced polypropylene and other materials. Various shapes and specifications. This product has the functions of high efficiency, energy saving and unique structure. After the product was put on the market, it was welcomed and praised by the majority of users for its unique design and reliable quality, and was selected by many units as a substitute for imported products.
Working Principle
The chemical self-priming pump is mainly composed of a liquid storage chamber, a vortex chamber, a return hole, an impeller, and a pump cover. Pressurized into the gas-liquid separation chamber. At this time, the specific gravity of the air is lower than that of the liquid, and it will naturally enter the pipe network. The liquid will automatically flow back from the return hole and mix with the air in the liquid storage chamber. ...This process is repeated until the air in the suction line is exhausted; the medium is transported to any place required by the working condition.
Application
The chemical self-priming pump can be used in the occasions where the liquid storage container is 1-4 meters below the ground level, and it is inconvenient to pour back and add liquid; the pump can be fixed on the ground level post to continuously or intermittently pump and transport various chemical media. Vehicles and ships loading and unloading chemical media. The self-priming pump can flow and pump at any position to meet your requirements.
Features
1. The pump has a reliable seal and adopts a non-leakage sealing device, which is composed of a dynamic seal and an auxiliary seal. It replaces the packing seal and mechanical seal of the traditional water pump, and completely solves the problems of "running, popping, dripping, and leaking" of the traditional seal. It is the most ideal product to replace the original long-axis submerged pump, submersible pump, submersible sewage pump, etc. 2. The sealing device of the self-priming pump has no friction and no wear during operation, and its service life is more than 10 times longer than that of traditional products. The self-priming performance of the transplanted vacuum pump is stable and reliable, especially the "electric air control valve" is used to truly realize the first drainage and permanent self-priming. The pump unit has small vibration, low noise, flexible movement, and convenient disassembly and assembly. It has superior automatic control function and can be matched with related control systems to realize high automation.
