The information is very detailed; I’m unable to upload images. You’re welcome to visit the original website for more details: http://www.ahxfbf.com/chanpin/lxb/fsbfsbdfusuliaoli*nbeng/6.html. I. FSB Fluoroplastic Alloy Centrifugal Pump – (Product Introduction) Design features: It is a single-stage, single-suction, cantilever-type centrifugal pump. Its flow components are made of pure fluoroplastic alloy, with no impurities forming, making it highly suitable for transporting high-purity chemical substances. An external bellows mechanical seal is configured; the rubbing materials available are alumina vs. PTFE, silicon carbide vs. PTFE, and cemented carbide vs. cemented carbide. Users can choose the rubbing pairs as per their requirements. Uses: This product is widely applicable to: acid cleaning and painting processes in the pharmaceutical industry and automobile manufacturing ； Electrolyte transport in non-ferrous metal smelting ； Process flows such as chlorine water treatment, wastewater treatment, and acid addition in the ion-exchange membrane caustic soda project.

Installation location: (1) The pump should be installed and fixed on a stable base, free from vibrations caused by other machines. (2) Sufficient space should be reserved around the pump to facilitate its maintenance and repair. (3) The area of the foundation must be greater than the area of the pump base plate. (4) Place the pump unit on the foundation, and a cushion should be placed between the base plate and the foundation. 2. Piping: (1) The suction and discharge pipes of the pump should be supported; the pump itself should not be used as a support. The diameters of the inlet and outlet pipes should match those of the pump’s inlet and outlet ports. (2) To prevent debris from entering the pump, a filter should be installed at the inlet, with a filtering area that is 3 to 4 times larger than the cross-sectional area of the pipeline. (3) It is necessary to ensure that the installation height of the pump meets its net positive suction head, taking into account pipeline losses and the temperature of the medium. To avoid cavitation margin in the pump chamber. (4) The use of bends in pipes should be minimized, and the shortest possible pipes should be used. (5) Do not use pipes with protrusions or inverted U-shaped pipes; the inlet pipe should be connected upward at a slope of 1/100. (6) If the pump’s inlet diameter differs from that of the connecting pipe, an eccentric reducer should be used to keep the upper part horizontal. If connected reversely, the gas inside the pipe may not be able to escape. (7) The pipes must be connected correctly. Make sure the gasket between the flanges is not misaligned. If the sealing surface leaks air, the pump will not function properly and may be damaged. (8) If the outlet pipe is too long, the resistance will **increase**, and the integrity of the pump will be affected. These factors should be considered when selecting a pump. (9) To accurately meet the flow rate requirements under operating conditions, a gate valve should be installed on the outlet pipe ； To prevent water hammer damage that occurs when the pump is shut down, a check valve should also be installed. The correct installation order is: pump – check valve – gate valve. (10) Agitators cannot be installed within 5 meters of the pump’s operating center, as this will severely affect the pump’s performance. 3. Startup and operation: 1) Before starting the pump, fill it with the liquid to be transported (in the case where the pump draws liquid in), close the outlet gate valve, and connect the power supply. Connect the power supply and check whether the pump rotates in the correct direction. (2) Run the unit for 5 to 10 minutes; if there are no abnormal phenomena, it can be put into operation. (3) When shutting down the machine, the outlet gate valve should be closed first, and then the power supply should be cut off. Maintenance: (1) Regularly inspect the pump and motor, and replace worn-out parts. (2) When the pump is not in use for a long time, the flow channels inside the pump should be cleaned and the power supply should be disconnected. (3) Idle operation is strictly prohibited. VIII.
