Centrifugal Pumps

The most important features and advantages of self-priming centrifugal pumps are

• Automatic priming properties: Self-priming centrifugal pumps can remove air from the suction line and pump housing, creating a vacuum that draws in the liquid. This enables the suction of liquids without manual assistance or external pre-suction.
• Efficiency and reliability: These pumps offer reliable performance and are well suited for applications where a continuous flow of liquid is required, even after a temporary interruption.
• Versatility: Self-priming centrifugal pumps are suitable for a wide range of fluids and applications, including water supply, irrigation, drainage, industry and more.

However, it is important to note that the self-priming capability may be limited in certain situations, depending on the height difference between the pump and the liquid level, the viscosity of the liquid and other environmental conditions. It is advisable to consider the specific requirements of your application and, if necessary, seek expert advice from DIA Pumpen’s specialists to ensure that the self-priming centrifugal pump is the optimum solution.

Industrial centrifugal pumps are preferred in a wide range of applications and industries due to their special characteristics and ability to efficiently move liquids from one place to another. Here are some of the most common applications for industrial centrifugal pumps:

• Water supply: Centrifugal pumps are used in water supply systems to pump drinking water or process water from wells, rivers, lakes or other sources. They are also used in waterworks to treat water and pump it into the distribution network.
• Heating and cooling systems: Centrifugal pumps are used in buildings and industrial plants to circulate heating and cooling media. They ensure that heat or cold is distributed efficiently.
• Waste water treatment: Centrifugal pumps are used in sewage treatment plants and wastewater treatment plants to move wastewater and treatment chemicals. They support the clarification process and the transportation of purified water.
• Chemical and petrochemical industry: Centrifugal pumps are used in the chemical and petrochemical industry to transport various chemicals and liquids for manufacturing processes. They often have to be corrosion-resistant and able to handle aggressive chemicals.
• Oil and gas industry: In the oil and gas industry, centrifugal pumps are used to transport crude oil, natural gas and various liquids in production and processing plants.
• Food processing: Centrifugal pumps are used in the food industry to pump food ingredients, beverages, dairy products, sauces and other liquids. They must meet hygiene standards and must not introduce any impurities into the products.
• Agriculture: In agriculture, centrifugal pumps are used for irrigation systems, pesticide or fertilizer distribution and for moving water in livestock facilities.
• Construction industry: Centrifugal pumps are used on construction sites to mix and pump concrete, mortar and other building materials.
• Paper supply and processing: Centrifugal pumps are used in the paper industry to transport water and chemicals for various paper manufacturing processes.
• Energy industry: Centrifugal pumps are used in power plants to circulate coolants or other fluids in heat exchange systems.

This list is by no means exhaustive, as centrifugal pumps are used in a wide range of industrial applications due to their versatility and efficiency. The exact application depends on the specific requirements of the respective industry and process. Please contact the DIA Pumpen team for a solution to your specific requirements.

The high-pressure centrifugal pump differs from a normal industrial centrifugal pump mainly in its ability to pump liquids at a significantly higher pressure. Here are the main differences:

• Pressure level: The DIA pumps high-pressure centrifugal pumps are specially designed to pump liquids at higher pressure values. While normal industrial centrifugal pumps are generally suitable for medium to low pressures, high-pressure centrifugal pumps are designed to achieve considerably higher pressure levels.
• Construction: Our high-pressure centrifugal pumps use even more robust materials to withstand the higher pressures. Their construction, especially the rotors, housings and seals, is reinforced to prevent leaks and structural problems.
• Performance: High-pressure centrifugal pumps generally have a lower flow rate compared to normal centrifugal pumps. This is because the energy is needed to bring fluids to higher pressures, which can affect the flow rate.
• Applications: High-pressure centrifugal pumps from DIA Pumpen are used in areas where precise control of pressure is required, such as in high-pressure cleaning, industrial plants, water treatment, injection molding or in processes that require precise metering of liquids at high pressure.

It is important to consider the specific requirements of your application in order to select the right type of pump, be it a normal industrial centrifugal pump or a high-pressure centrifugal pump. Please contact the pump specialists at DIA Pumpen to select the right pump for your needs.
