Corrosion-resistant sewage pump is a centrifugal pump, according to the material can be divided into two types: stainless steel sewage pump and fluorine-lined sewage pump (also known as single-stage single-suction fluorine plastic alloy chemical centrifugal pump); According to the use can be divided into Two kinds: submersible and dry two. Now on the market of stainless steel sewage pump submersible and dry two, and lined fluorine sewage pump only a dry one. What are the characteristics of corrosion-resistant sewage pump? What are the characteristics? (A) WQF submersible stainless steel sewage pump features 1, WQF stainless steel sewage pump with stainless steel design, from the pump, seal, motor three parts. The motor is located in the upper part of the electric pump, which is a single-phase or three-phase asynchronous motor structure. The water pump is located at the lower part of the electric motor and adopts the suction structure to prevent the electric pump from being clogged in the sludge. Shape using precision casting and stainless steel barrel, beautiful, rust-proof, corrosion-resistant, non-polluting and so on. Widely used in various special requirements such as chemical industry, marine culture, food and beverage use occasions. 2, the electric pump uses a double-end mechanical seal, with a sealed and reliable use of safety features. Seals and cables according to the media use of corrosion-resistant fluorine rubber, health and safety. 3, the pump overall compact structure, small size, light weight, easy maintenance, diving liquid can be used. Electric pump installed inside the over-temperature current protection, to prevent the motor overheating due to overload. (B) PWF dry stainless steel sewage pump characteristics PWF stainless steel sewage pump is a single stage, single suction, cantilever centrifugal sewage pump. Pump inlet for the axial horizontal direction, the pump outlet can be installed according to the needs of the horizontal or vertical direction. Mainly by the pump cover, pump housing, impeller, shaft seal, shaft, and brackets and other components. Shaft seal with a novel double-sided mechanical seal structure, the pump and motor mounted on a common chassis, through the flexible coupling directly driven by the motor. The pump has high efficiency, significant energy saving, stable operation, reliable performance, easy maintenance and so on. (III) Lining fluorine sewage pump lined fluorine sewage pump, also known as single-stage single-suction fluorine plastic alloy chemical centrifugal pumps, according to international standards and design of non-metallic pump design and manufacturing process. The pump body is lined with a metal shell and filled with FEP. The pump cover, impeller and bushing are all pressed and sintered with a metal insert which is completely sintered with fluorine plastic. The shaft seal adopts the mechanical seal with advanced external bellows, Ring selection of 99.9% alumina ceramic (or silicon nitride), moving ring with PTFE filling material, the corrosion-resistant wear-resistant seal is excellent. Import and export of the pump are used steel reinforcement, to enhance the pressure resistance of the pump. Actual use shows that the pump has the advantages of corrosion resistance, abrasion resistance, high temperature resistance, no aging, high mechanical strength, stable operation, advanced and reasonable structure, strict and reliable sealing performance, easy disassembly and maintenance, long service life and the like.
