First, under FYS type plastic liquid pump Products: pump is vertical single-stage single-suction centrifugal pump under FYS type corrosion submerged for conveying solid particles and corrosive liquid crystal is not easy, mainly to solve the highly corrosive medium transport issues. The pump is characterized by a vertical structure, the pump impeller partially submerged in the liquid, it occupies a smaller area, seal leak and, therefore, suitable for handling corrosive liquids. The pump can be hazardous area and non hazardous area use, where the use in hazardous areas explosion-proof electrical configuration, these motors in three group-level models, when the use of various flammable and explosive mix should be used in the highest group level . Second, under FYS-resistant submerged pump-type plastic Features: under FYS-resistant submerged pump-type plastic, it is a direct immersed in a chemical medium in the vertical centrifugal pump for pumping liquid pump fusion of a whole and non-metallic advantages of metal in one of the design objects, lined with plastic and metal as a whole package, compounding, extrusion and other manufacturing processes, corrosion resistant, steel is good, no leakage, light weight, easy maintenance. Based on differences in media, temperature, in order to meet the needs of different users, the factory can be used are poly FEP (F46) and reinforced polypropylene material (FRPP) production under FYS type liquid pumps for temperature F46, -50 ℃ ~ 120 ℃, FRPP, -5 ℃ ~ 90 ℃. FYS-type submerged pump is widely used acid, dyes, pesticides, pharmaceuticals, metallurgy, petrochemicals, electroplating, environmental protection and other industries. See table corrosion resistance. Note: To prevent liquid pumps idle load, static and dynamic bearing damage, can be equipped with our factory production "ZK" multi-functional since the controller. Third, under FYS-resistant submerged pump-type plastic model significance: 2.jpg IV pump performance range of engineering plastics corrosion submerged under FYS: liquid depth: 250mm ~ 3000mm, flow: 1.5m3 / h ~ 400m3 / h, Head: 6m ~ 50m, speed: 1450r / min ~ 2900r / min, temperature: -5 ℃ ~ 105 ℃ Model significance: 50 FYS-25-1000E E represents the shaft material 1000 is the liquid depth 1000mm 25 indicates the head of 25m FYS represents corrosion-resistant plastic liquid pump inlet diameter 50 mm represents the structure and materials A: reinforced polypropylene - corrosion resistant stainless steel (FRPP-1Cr18Ni9Ti) B: reinforced polypropylene - Titanium (FRPP-Ti) C: reinforced polypropylene - other metals D: reinforced polypropylene - fluoroplastic alloy E: reinforced polypropylene - acrylic plastic packages in addition to the shaft, and wetted parts of the material are the following: F4, silicon nitride, silicon carbide, titanium, reinforced PP to prevent deformation of the problems caused by thermal expansion and contraction, the pump connecting pipe outsourcing plastic composite pipe inside. Axial force and radial force generated during operation of the pump by an adjustable bearings to ensure smooth operation noise. Equipped with water pump lower bearing, more than 1.5 meters deep sump pump with intermediate water bearing to ensure smooth and reliable operation of the pump.
