DEF SS Submersible Pump STP
Chemical submersible pumps play a crucial and irreplaceable role in modern industrial and commercial fuel - supply systems. Primarily, they are designed for use with underground tanks. Their main function is to efficiently push the liquid stored within these underground tanks to the refueling machines. This is of great significance as it ensures a smooth and continuous fuel - supply process at gas stations, industrial fuel depots, and other related facilities.
One of the remarkable features of these pumps lies in their structural design. The rotor is wrapped with 304 stainless steel and paired with special graphite bearings. This combination endows the parts of the product that come into contact with the liquid with excellent pollution - free and corrosion - resistant properties. The use of 304 stainless steel is well - known for its durability and resistance to oxidation, while the graphite bearings offer low - friction operation and high wear resistance. These characteristics not only extend the service life of the pump but also expand its scope of application. It can handle a wide variety of liquids, including those with certain corrosive properties, thus making it suitable for different industrial scenarios.
Let's take a detailed look at the product features:
National Certification: The pump has obtained national certification, which means it meets strict safety and quality standards. This certification allows it to be safely used in dangerous areas where there may be a risk of fire, explosion, or other hazards. For example, in areas with flammable vapors or gases, this certified pump can operate without posing a significant safety threat.
No Cavitation: Cavitation is a common problem in pump operation, which can cause damage to the pump components and reduce its efficiency. This chemical submersible pump is designed to prevent cavitation. It can maintain a stable flow of liquid, ensuring that the pump operates smoothly and effectively.
Built - in Thermal Protection: Safety is always a top priority. The built - in thermal protection system is a key safety feature. It continuously monitors the temperature of the pump's motor. If the temperature rises to an unsafe level, the pump will automatically shut down to prevent damage to the motor and other components. This makes the pump safe and reliable during long - term operation.
All 304SS Material: The entire pump is made of 304 stainless steel. This material provides excellent anti - rust and anti - corrosion properties. It can withstand the harsh environment of underground tanks, where the liquid may contain various impurities and corrosive substances. The use of 304SS material also reduces the need for frequent maintenance and replacement of parts.
Positive Pressure Oil Supply: The pump uses a positive pressure oil - supply mechanism, which enables it to have a long infusion distance. It can effectively transport the liquid from the underground tank to the refueling machine even if the distance is relatively long. This is very important for large - scale fuel - supply systems.
One Pump with Multiple Filling Machines: A single pump can be connected to multiple filling machines. This design increases the efficiency of the fuel - supply system. It reduces the number of pumps required, thereby saving costs and space.
Built - in Pressure Relief Device: To maintain a safe line pressure, the pump is equipped with a built - in pressure relief device. If the pressure in the pipeline exceeds the safe limit, the pressure relief device will open to release the excess pressure. This protects the pump and the entire fuel - supply pipeline from damage due to over - pressure.
Motor Stator Built - in Temperature Control Protector: In addition to the thermal protection system, the motor stator also has a built - in temperature control protector. It can precisely monitor the temperature of the stator. When the motor current exceeds the normal value, which may indicate an abnormal operating condition, the submersible pump will automatically shut down. Also, when the highest internal temperature of the motor reaches 95°C, the pump will stop operating to avoid overheating and potential damage.
The key processes in the manufacturing of this chemical submersible pump. First, the inner and outer sleeves are welded together with the upper and lower glands. Then, the inside cavity undergoes vacuum pressure encapsulation with epoxy resin. This process provides excellent insulation and protection for the internal components of the pump. After that, a water pressure test and an insulation performance test are carried out. These tests ensure that the pump can withstand the pressure of the liquid and maintain good electrical insulation properties. The stator embedded line part is covered by the inner and outer sleeves, and the upper and lower ends are wrapped inside. This design further protects the stator from damage and ensures the normal operation of the motor.
In conclusion, the chemical submersible pump offers a reliable, efficient, and safe solution for liquid transfer from underground tanks to refueling machines, with many advantages over traditional long - shaft submersible pumps.
