The positive displacement pump is a kind of fluid transportation equipment, which is widely used in many different fields and scenarios. Its uses and scenarios are diverse. The main application fields will be described in detail below.

Positive displacement pump, also known as propulsion pump, is a kind of pump equipment that uses volume change to promote fluid. The main components of the positive displacement pump include the pump body, the rotating impeller, the rotating vane plate and the control valve. The pump body is one of the most important parts in the positive displacement pump. It is the fluid delivery path. The rotating impeller mainly plays the role of compressing and conveying fluid. The rotating vane plate is the component that controls the volume change of the pump chamber. The control valve is used to control the flow. The size and direction of the flow, so as to achieve the purpose of automatic control.

1. industrial field

1. Petrochemical: Volumetric pumps are widely used in the petrochemical industry to transport various liquid raw materials, additives, reactants, etc. Its precise flow control and stable performance make it an irreplaceable role in highly demanding processes. The positive displacement pump can transport various chemicals, such as fertilizers, metallurgy, dyes, pigments, coatings, etc., because the structure and performance of the positive displacement pump are suitable for the transportation of high viscosity and corrosive fluids.

2. Pharmaceutical industry: In the pharmaceutical process, positive displacement pumps are used to transport various drugs, solvents, slurries, etc. to ensure the continuity of the production process and the stability of the product. The positive displacement pump can be used in the pharmaceutical field to deliver various liquid preparations, such as suspensions, emulsions, aerosols, etc. At the same time, in the pharmaceutical industry, the purity of the conveying liquid is very high, and the choice of the material of the positive displacement pump is a very important issue. Positive displacement pumps have unique advantages in the delivery of various medical liquids, such as blood, plasma, heparin, toxicological chemical treatment and drug delivery. The choice of material for a positive displacement pump is critical to the purity of the liquid being transported.

2. Architecture and Municipal Areas

1. Water supply system: Volumetric pumps play an important role in the municipal water supply system to ensure the stability of the water volume and water pressure of the urban water supply.

2. Sewage treatment: In the sewage treatment process, positive displacement pumps are used to transport sewage and sludge to ensure the normal operation of sewage treatment equipment.

3. food and agriculture sector

1. Food processing: The positive displacement pump is used to transport various fluid foods in the food processing process, such as dairy products, fruit juices, sauces, etc. Its good hygienic performance and precise flow control ensure the quality and taste of food. Positive displacement pumps can be used to transport a variety of food: sauce, syrup, batter, juice and cocoa, especially for food with high palatability and quality requirements, positive displacement pumps provide a reliable solution.

2. Agricultural irrigation: In the agricultural field, positive displacement pumps are used for agricultural irrigation to ensure that crops get the right amount of water.

4. other areas

1. Mine metallurgy: positive displacement pumps are used to transport slurry and slag in the mine metallurgy industry to ensure the smooth progress of the production process.

2. Power generation and energy industry: In the power generation and energy industry, positive displacement pumps are used to transport fuel, coolant, etc. to ensure the normal operation of equipment.

Laboratory and scientific research: In laboratory and scientific research scenarios, positive displacement pumps also play an important role in accurately controlling fluid flow to meet the needs of experiments and research.

The positive displacement pump is widely used in various fields. Whether it is high viscosity chemicals or food products with high palatable and quality requirements, positive displacement pumps can provide users with reliable liquid delivery solutions.

In short, the application range of positive displacement pumps is very wide, covering almost all areas that require fluid transportation. Its stable performance, precise flow control and good adaptability make it perform well in various scenarios. Whether it is industry, construction, agriculture or food and scientific research, the pump is an indispensable important equipment.
