FSB Fluoroalloy Centrifugal Pump

1、 Overview of FSB Fluoroplastic Pump

The FSB type fluoroplastic alloy pump is designed according to international standard dimensions. The pump body is made of metal and polytetrafluoroethylene (F46) organic combination. The pump cover, impeller, and shaft sleeve are all wrapped in metal inserts and made of fluoroplastic material through computer controlled sintering and pressing. The shaft seal adopts an external corrugated pipe mechanical seal. The static ring is made of 99% alumina ceramic or silicon nitride, and the dynamic ring is filled with PTFE material, which is corrosion-resistant and wear-resistant. It is suitable for transporting any concentration of sulfuric acid, hydrochloric acid, acetic acid, hydrofluoric acid, nitric acid, aqua regia, strong alkali, strong oxidant, organic solvent, oxidant and other harsh working conditions. It is currently one of the materials in the world that is resistant to strong corrosion. Fluoroplastic alloy pumps are widely used in industries such as chemical, acid, alkali, smelting, rare earth, pesticide, dye, pharmaceutical, papermaking, electroplating, electrolysis, acid washing, electronic components, and scientific research institutions to prevent running, emitting, dripping, and leaking.

IIICharacteristics of Fluoroplastic Alloy Centrifugal Pump Products：

The FSB type fluoroplastic alloy pump consists of a pump body, impeller, cover, seal, bracket, pump shaft, coupling, suspension bolt, nut, base plate, etc.

1. Pump body: One steel flange ring is embedded on each side of the connecting department and molded into plastic alloy. It has the advantages of compact and reasonable structure, strong corrosion resistance, tight and reliable sealing function, stable operation, low noise, high mechanical strength, no aging, no toxin decomposition, easy maintenance, smooth flow channel, high efficiency, and energy conservation.

2. A stainless steel (1Cr18Ni9Ti) plastic alloy is embedded on the right side of the cover.

3. Impeller: The shaft connection method is adopted, and the metal shaft is made of high-quality steel round processed and wrapped with fluoroplastic high-temperature compression molding, so that the impeller and the metal shaft are firmly integrated, ensuring that the shaft root and the rear of the impeller bear the torque force during rotation. In this way, the overcurrent part of the medium is made of plastic alloy.

4. Mechanical seal: Adopting WB2 and ST adjustable single end mechanical seal technology without cooling water, made of materials such as silicon carbide, high-purity alumina ceramics, filled PTFE, graphite, etc.

6、 FSB pumpInstallation and Precautions for Use
Before installation, the pump and motor should be inspected to ensure that all parts are intact and free of debris inside the pump.
2. Place the pump in a horizontal position, connect the inlet and outlet pipes, and connect the power supply Then manually rotate the coupling Check for any signs of collision or rubbing If the rotation is easy and uniform, the installation is complete.
3. Plastic alloy pumps have lower rigidity than metals, so the weight of the pipeline cannot be directly pressed on the pump body. Additional brackets should be added to support the inlet and outlet pipelines Pumps with high head should also be equipped with check valves at the outlet To prevent water hammer damage caused by sudden shutdown.
4. All joints must be kept sealed To prevent air leakage and liquid from affecting the working performance of the pump.
5. If there is any movement or abnormal sound during operation Immediately stop the vehicle to investigate the reason Therefore, work can only be carried out after elimination.
Start and Stop
1. Fill the water pump with sufficient liquid (drainage).
2. Check if the oil level in the bracket oil chamber is within the specified range.
3. Check the direction of motor operation Check the rotation mark of the pump.
4. Close the outlet valve and pressure gauge plug.
5. Start the motor Open the pressure gauge plug Slowly open the outlet valve, when the pressure is high
When making an important stop, first close the water outlet valve and then cut off the power supply.
When the pointer of the force gauge points to the desired position Stop adjusting the size of the outlet valve.

7、 FSB pumpDismantling and installation
Disassembly of pump
1. The pump and motor are connected using a claw type coupling. When disassembling, first loosen the four connecting bolts between the bracket and the base Disconnect the pump from the motor.
2. Loosen the connecting bolts of the pump body back cover Gently tap the pump body with a wooden handle to detach it.
3. Loosen the suspension bolts connecting the impeller shaft and pump shaft with a Mohs taper in the coupling.
4. Release the mechanical seal! Without fixing the screws, lightly tap the central suspension bolt of the coupling with a wooden hammer, loosen the Mohs taper of the impeller shaft and pump shaft, and then pull out the impeller, rear cover, and sealing ring Loosen the cover screw on the back cover Remove the static damage.
5. Loosen the left and right cover screws of the pump shaft Remove the pump shaft, bearings, and clean the bracket oil chamber.
