What Type of Pump is Used for Sulfuric Acid？
Pumping Sulfuric Acid
As a chemical liquid that can corrode most metals, ordinary chemical pumps can no longer meet the requirements of sulfuric acid transmission. The professional sulfuric acid pump designed for pumping sulfuric acid can meet the handle of acid fluid.
The sulfuric acid transfer pump is the most common among the pumps usually used for chemical addition.
However, Which pump is used for sulphuric acid? The answer to this question is not unique.
Just choose from the structure, whether it is a magnetic drive pump, a vertical pump, a centrifugal pump, a metering diaphragm pump, a pneumatic diaphragm pump, or even a submersible pump, it can transmit sulfuric acid, and the decisive factor is not the structure, but the sulfuric acid—non-reactive material.
Sulfuric Acid
Sulfuric acid corrosive As one of the solid corrosive media, sulfuric acid is an important industrial raw material with many uses. Sulfuric acid is one of the most active binary inorganic strong acids, which can react with most metals. High-concentration sulfuric acid has strong water absorption and can be used as a dehydrating agent to carbonize carbohydrate-containing substances such as wood, paper, cotton, linen fabrics, and natural skin. It also releases much heat when mixed with water. It is highly corrosive and oxidizing, so You should use it cautiously.
Therefore, for the characteristics of sulfuric acid, the first thing to ensure is the following:
1. Corrosion Resistance: The high corrosiveness of sulfuric acid makes the material requirements very high. No company wants its pump replaced due to corrosion after three months. For sulfuric acid with less than 80%, essential plastics can be used, such as PP, PVDF, ETFE (polytetrafluoroethylene), and other materials. For the attention of more than 80% and the temperature less than 90 °C, you can choose PVDF or ETFE plastic pumps.
2. Safety Factor: The corrosiveness of sulphuric acid makes safety in the production environment paramount. In many cases, the chemical acid pump must meet the acid resistance and be able to withstand higher temperatures. If conditions permit, a chemical pump without a shaft seal will be the best choice, saving you a lot of operation and maintenance costs.
3. Manufacturer's experience: choosing a chemical pump manufacturer with many years of manufacturing experience will make the branded sulfuric acid pump more secure in terms of safety factors and adaptability. We have been engaged in producing and manufacturing chemical pumps for more than 20 years.

Working principle of vertical multistage pump
A vertical multistage centrifugal pump is a kind of vertical pump which belongs to stainless steel multistage pump with a standard vertical motor and quick-install mechanical seal.
Its flow parts are cast iron and stainless steel (304, 316, 316L stainless steel).
The difference between the vertical multistage pump and the vertical single-stage pump is that the vertical multistage pump has more than two sets of impellers. The pump operates by using the centrifugal force generated by the fluid flows generated by the rotation of the impellers.
When the motor of the vertical multistage centrifugal pump drives the impeller on the shaft to rotate at high speed, the liquid filled in the impeller, under centrifugal force, fluid enters the impeller center along the flow channel between the blades to the surrounding of the impeller.
The action of the vanes increases the pressure and speed simultaneously and is guided to the impeller of the next stage through the flow channel of the guide casing.
After each impeller is superimposed, a particular head is obtained.
In addition, due to the use of an intelligent multistage variable frequency motor, the motor can be adjusted automatically according to the needs of the flow.
Application of vertical multistage centrifugal pump
1. Fire pipeline pressurization;
2. Cold and hot water circulation is used for air conditioning;
3. Circulating pressurized transportation in the production process, suitable for the matching use of various drainage equipment, boilers, and other equipment;
4. The product is suitable for low-viscosity, neutral, non-explosive liquid without solid particles or fibers, and the liquid to be transported cannot be chemically corrosive to the pump material;
5. Water treatment, infiltration, and filtration systems;
6. Food and beverage industry;
7. Water supply for high-rise buildings;
8. Industrial cleaning system.
In many cases, users usually consider their use value when choosing a product, and its use usually reflects the use-value of a product.
The above is the introduction of the working principle of the vertical multi-stage pump. If you choose a high-quality vertical multi-stage pump or a vertical single-stage pump, please leave a message to us to obtain the product information white paper.

The Applications of the Dubao Pumps
The application of the pump has a wide range. If it is distinguished by size, the large industrial pump can transmit tens of thousands of cubic meters of liquid per hour, while the smallest pump can control the flow rate to 1% ml per minute.
Many types of liquids are transported by pumps, including water (pure water, tepid water), medicinal liquids, acidic liquids, alkaline liquids, etc.
In the oil and gas industry, there are often high-viscosity, high-risk flammable liquid transfer requirements, so positive displacement pumps play a role in transporting liquids and providing pressure flow for chemical reactions in these processes, such as gear pump, lobe pump, piston Pump, etc., in addition, pumping systems are used in many installations to adjust the temperature.
In agricultural irrigation, irrigation pumps are the central irrigation and drainage machinery. Every year, a large number of pumps are needed in the countryside. Generally speaking, agricultural single-stage water pumps account for more than half of the total pump output.
Nuclear power plants need primary, secondary, and tertiary pumps in the power sector, and geothermal power plants need a lot of feed water centrifugal pumps, condensate pumps, circulation pumps, etc.
In the military field, the adjustment of flight equipment components, the shooting direction of armored vehicles, and air conditioning equipment all need to use pumps to achieve their goals, such as dynamic pumps. Some also require a high-pressure pump without any leakage.
Due to the massive demand for the flow rate of liquid transmission in the shipbuilding industry, up to hundreds of various pumps are often used on each ship, such as feed pumps, drainage pumps, fire pumps, etc.​​
In short, whether it is cars, boats, aircraft, manufacturing, or ordinary life, pumps are everywhere. Therefore, pumps can be the most common type of mechanical product in the machinery industry.
Our products include acid and alkali resistant pumps, vertical pumps, horizontal pumps, magnetic pumps, and self-priming pumps. Mainly used in electroplating, PCB, LED, continuous electroplating, chemical, medical, environmental protection and coating, and other fields.
Others, such as urban water supply and drainage, will use booster pumps; water treatment plants will use sewage pumps, dyes in the textile industry, pulp in the paper industry, and various weakly acidic and alkaline types liquids food industry. This plays a crucial role, among which suction pumps and peristaltic pumps are the more common pumps.​​
