stainless steel chemical pump uses stainless steel as the main material. based on the principle of centrifugal pump, it has strong corrosion resistance and reliability.

Stainless steel chemical pumps are primarily made of stainless steel and operate based on the principle of centrifugal pumps. They are highly resistant to corrosion, have high reliability, and are widely adaptable. They are used in multiple industries, including chemical industries, and maintenance should focus on operating parameters and seals.Definition and Use

Stainless steel chemical pumps are specially designed for the chemical industry, primarily made of stainless steel materials, and are used to transport various media with special working conditions such as corrosion, high temperature, and high pressure. They are widely used in chemical, petroleum, metallurgy, pharmaceutical, food and other industries, and can be used to transport acid and alkaline liquids, chemical solvents, and high-temperature oils and other substances.

Structural Features

- Material: The main flow parts (such as pump body, pump cover, impeller, etc.) are made of stainless steel materials, including 304, 316, 316L, etc. 316L stainless steel has strong corrosion resistance and is suitable for strong corrosive media; 304 stainless steel has lower cost and is used in environments with weaker corrosion.

- Impeller: Various forms, closed impellers are efficient and suitable for cleaning media; open, semi-open impellers are not easily clogged and can be used to transport media containing solid particles or impurities.

- Sealing Devices: Mechanical seals are quite common and can effectively prevent medium leakage, suitable for situations with high sealing requirements. There are also packing seals, which have a simple structure but have a slightly inferior sealing effect and service life compared to mechanical seals, often used in situations with lower requirements.

Working Principle

Based on the principle of centrifugal pumps, the motor drives the impeller to rotate at high speed, causing the liquid in the pump to be thrown from the center of the impeller to the outer edge by centrifugal force, increasing the pressure and velocity. After the liquid enters the pump casing, some of its kinetic energy is converted into static pressure energy, and it is discharged through the outlet. Meanwhile, a low-pressure area is formed in the center of the impeller, and under the action of external pressure, the liquid continuously enters the pump through the suction pipe, achieving continuous transportation.

Advantage

- Strong corrosion resistance: The stainless steel material allows it to resist the corrosion of various chemical media, extending service life and reducing the cost of equipment replacement and maintenance.

- High reliability: Reasonable structural design and advanced sealing technologies such as mechanical seals ensure the stability of operation, reduce the risk of leakage, and ensure the safety and continuity of production.

- Wide adaptability: Customized design and selection can be made according to the characteristics, flow rate, and head requirements of different media, meeting the diversified industrial needs.

Maintenance Points

- Regular inspections: Regularly check the operating status of the pump, including flow, head, current, vibration, and other parameters, and promptly identify and handle any anomalies.

- Sealing Maintenance: Monitor the leakage situation of mechanical seals and replace the sealing fluid (if any) regularly; for gasket seals, adjust the tightness of the gasket cover in time, and replace the gasket if necessary.

- Cleaning and maintenance: For pumps that transport media that are prone to crystallization or sedimentation, it is important to clean the pump chamber after operation to prevent residual media from causing blockage or corrosion.
