Similar to ordinary gear pumps, the stainless - steel submersible gear pump mainly consists of components like the pump body, stainless - steel gears, main and passive shafts. As the driving gear propels the driven gear to rotate, in the liquid - suction cavity where the teeth gradually disengage, the enclosed volume between the teeth expands, generating a local vacuum. Under the influence of the pressure differential, the liquid is drawn into the liquid - suction chamber. As the gears keep rotating, the liquid is pushed forward in two routes between the gears and the pump casing by the gears and then delivered to the liquid - discharge cavity. In the liquid - discharge cavity, the two gears gradually engage, the volume decreases, and the liquid between the gears is squeezed out to the liquid - discharge port, thereby enabling the transportation of the liquid.
High Corrosion Resistance: Constructed from stainless - steel materials such as 304, 316, 316L, etc., it can withstand the corrosion of corrosive media including acids, alkalis, and salts, and is capable of transporting various corrosive liquids.
Good Wear Resistance: Key components such as gears undergo special treatment, boasting high hardness and strength. When transporting liquids containing minute particles or having certain friction, it can effectively minimize wear and extend the service life.
Compact Structure: Typically adopting a vertical structure, it can operate submerged in liquid as required. It occupies a small footprint, is easy to install, and can adapt to diverse installation environments.
Good Sealing Performance: Generally, advanced sealing technologies like mechanical seals are employed to ensure that there is no leakage during the pump's operation, safeguarding the safety and stability of the transported liquid.
Stable Flow Rate: By relying on the continuous meshing and separation of gears, it transports liquid with a uniform output flow rate and minimal pulsation, providing a stable liquid supply for the production process.
Chemical Industry: It is utilized to convey various corrosive liquids such as chemical raw materials, acid - base solutions, and organic solvents, for example, sulfuric acid, hydrochloric acid, sodium hydroxide solution, etc.
Petroleum Industry: It can transfer petroleum products such as crude oil, lubricating oil, and fuel oil, playing a crucial role in aspects such as oilfield exploitation, petroleum refining, and petrochemical engineering.
Pharmaceutical Industry: Suitable for transporting pharmaceutical raw materials, liquid medicines, solvents, etc., it meets the liquid transportation and metering requirements in the pharmaceutical production process and complies with the hygienic standards of pharmaceutical production.
Food and Beverage Industry: It can handle food raw materials and finished products like edible oil, fruit juice, milk, and syrup. Given that the stainless - steel material is non - toxic and hygienic, it will not contaminate food.
Environmental Protection Field: In environmental protection projects such as sewage treatment and seawater desalination, it can be used to transport liquids such as sewage, seawater, and chemical agents.
Flow Rate and Pressure: Ascertain the necessary flow rate and pressure parameters based on actual usage requirements to ensure that the pump can fulfill the demands of transporting the liquid volume and surmounting pipeline resistance.
Medium Characteristics: Take into account the corrosiveness, viscosity, temperature, and particle - content of the transported medium, and select the appropriate stainless - steel material and pump structure to ensure the normal operation and service life of the pump.
Installation Method: Choose a suitable installation approach, such as vertical or horizontal, according to the on - site installation conditions. The stainless - steel submersible gear pump is usually installed vertically and can be directly inserted into the liquid container for operation.
Motor Power: Select a matching motor power according to the pump's flow rate, pressure, and medium characteristics to ensure that the motor can supply sufficient power for the pump while avoiding motor overload.
