Overview of SL type fiberglass pipeline pump:
The S-type, FS type, SL type, SY type, WSY type, and FSY series fiberglass pumps are made of polyvinyl butyral and modified phenolic glass fiber materials that are molded at high temperatures for liquid contact. They have good corrosion resistance, high temperature resistance, light weight, high specific strength, and no deformation. The shaft seal adopts two types: ordinary and particle resistant machine seals (mechanical seals are not used for submersible pumps), with a reasonable structure and low power consumption.
Shaft seal: Adopting WB2 external F4 corrugated mechanical seal, the seal is reliable, the seal is reliable, and the service time is long.
Transmission: The pump is directly driven by an electric motor through a claw type elastic coupling.
Application scope of SL type fiberglass pipeline pump:
This pump is mainly used in industries such as petrochemicals, smelting, dyes, printing and dyeing, pharmaceuticals, rare earths, leather, etc. It is an ideal equipment for transporting various non oxidizing acids and other corrosive media that do not contain solid particles, are not easy to crystallize, and have a temperature not exceeding 100 ℃.

Installation, use, precautions, and maintenance of SL type fiberglass pipeline pump:
1. Before installation, the vertical glass pipeline pump should be equipped with a foundation according to the selected pump type, shape, and installation dimensions. During installation, the installation location should be as convenient as possible for management and maintenance based on the requirements of the pipeline position.
2. If the installation position of the pump body is higher than the liquid level, a filling device must be attached.
3. Before starting the fiberglass pipeline pump, fill the pump body with liquid and then drive it. It is strictly prohibited to operate or reverse without a medium, otherwise the mechanical seal of the pump body will be damaged due to the lack of liquid cooling.
4. When parking, the liquid pipe valve should be closed to avoid liquid backflow.
5. Regularly check and ensure that the motor current value does not exceed the rated current of the motor.
6. Pay attention to regular maintenance and regularly check if the pump runs smoothly. Check for any abnormal vibrations and replace the elastic block carefully. Add lubricating oil to the bearings according to the oil gauge, and regularly replace the lubricating oil in the frame. Generally, it must be replaced once every three months.
