Supply PF (FS) strong corrosion-resistant polypropylene centrifugal pump

■ PF (FS)-type high resistance to corrosion polypropylene centrifugal pump Product Overview: PF (FS) type strong corrosion-resistant polypropylene centrifugal pump pump pump cover, impeller, and media contact parts are made of polyvinylidene fluoride or enhanced polypropylene molded or injection mold made. The polyvinylidene fluoride Plastic (Annex II) (see Table I) high mechanical strength, good corrosion resistance is one of the wider application of international engineering plastics. PF (FS) type strong corrosion-resistant polypropylene centrifugal pump can satisfy conveying a temperature of -50 ° C to -80 ° C under the condition of various concentrations of sulfuric acid, hydrochloric acid, nitric acid, acetic acid, phosphoric acid, chromic acid, oxalic acid, hydrofluoric acid and lye. organic solvents, oxidizing agents and other chemical media, energy-efficient pumps for chemicals, chlor-alkali, fertilizers, dyes, reagents, pesticides, pharmaceuticals, electroplating, environmental protection and other industrial sectors conveying corrosive media without particles. ■ PF (FS) type strong corrosion resistant polypropylene centrifugal pump structure Description: PF (FS) type strong corrosion-resistant polypropylene centrifugal pump for direct connection structure, connected by the pump and bracket with motor flange bracket supporting pump body, impeller shaft and the motor is directly connected. This series of pump characteristics: simple and compact structure, fewer parts, and good performance. The direction of rotation of the pump from the suction port to see the direction of the motor is clockwise rotation, the pump outlet vertically upwardly. Pump seals, optional PTFE (F4) bellows, externally mounted corrosion-resistant mechanical seals. ■ PF (FS) type strong corrosion-resistant polypropylene centrifugal pump Product Features: PF (FS) type strong corrosion-resistant polypropylene centrifugal pump is the energy-saving centrifugal pump developed for particle-free strong corrosive medium. PF (FS) type strong corrosion-resistant polypropylene centrifugal pump with high mechanical strength, good corrosion resistance, energy saving and environmental protection, widely used, easy to maintain and can transport a variety of acids, alkalis and other advantages. Pump, pump cover, impeller, and media contact parts are made of polyvinylidene fluoride or enhanced a polypropylene molding process or injection processing. Liquid medium temperature -50 ℃ ~ 130 ℃. PF (FS) type strong corrosion-resistant polypropylene centrifugal pump is directly connected single-stage single-suction centrifugal pump, is a new type of energy-saving strong corrosion centrifugal pump. Strong corrosion resistant centrifugal pump by the spindle motor directly connected to the direction of rotation of the pump from the suction inlet to outlet axis vertically upwards to see the motor direction is clockwise rotation. Strong corrosion-resistant centrifugal pump seals, bellows, externally mounted corrosion-resistant mechanical seal selection of polytetrafluoroethylene (F4). Corrosion and temperature of the transmission medium, the pump wetted materials are divided into: (FRPP) reinforced polypropylene (symbol PR) Suitable temperature -5-80 ° C. Polyvinylidene fluoride (PVDF) polyethylene (Symbols PF) to a temperature of -30-110 ° C applies. Any use in hazardous areas, to be equipped with explosion-proof motor. ■ PF (FS) type strong corrosion-resistant polypropylene centrifugal pump assembly: 1 bracket with motor flange connection, tighten the bolts. 2. Mechanical seal stationary ring evenly fixed the pump cover with a clean gauze wipe; contention stationary ring end surface coated with a little oil, set into the impeller pump cover inside the packed stationary ring, and will automatically ring assembly in the access shaft. . Packed impeller pump cover mounted on the carriage, and the impeller then sleeve onto the motor shaft and tighten the bolts to prevent loosening. The pump, pump cover mounted on the carriage, screw evenly: bolts and hand plate moving impeller shaft severity frictionless better. 5.PF (FS) type chemical pump installation dimensions (see Table 2). ■ PF (FS) type strong corrosion-resistant polypropylene centrifugal pumps for use: 1. Car: (1) If the pump is installed above the liquid level, imports at the bottom need fitted bottom valve (one-way check valve), when used, shall pump are filled with liquid (water diversion). (2) Check whether the direction of the motor and pump steering signs prohibit reverse operation. (3) open the pipeline valve and pressure gauge, start the motor to adjust the size of the flow and pressure of the pump valve open. (4) under normal operating conditions, the mechanical seal allows leakage <5 ml / natural dropping by with a small container, the lower part of the face-to-face. (5) non halfway off the normal operation of the pump, liquid burn seals and components. (6) found that vibration or other irregularities, should stop and check excluded (Table III checks). 2. Parking: (1) a timely manner before stopping close the outlet valve to prevent liquid intrusion. (2) When the ambient temperature is below; night body freezing point, should be placed on net pump liquid. (3) If the long-term stop using the pump should be removable and washable cleaning, assembly and closed the import and export. 3. Mechanical seal: (1) mechanical seal suitable for use in clean, free of suspended particulate media. Response to the pump body, impeller, sealed chamber (2) before assembly rinse strictly check the snap ring, stationary ring, does not allow any minor scratches, and wipe clean with a clean gauze coated with a layer of clean oil. (3) properly adjust the amount of compression spring, should not be too tight or too loose, so that some of the pressing force, but also light and flexible rotation. (4) Remove the mechanical seal should carefully guard against impact damage static ring sealing surface.
