Side Channel Pumps

Industrial side channel pumps are a special type of pump used in industrial applications to pump or compress liquids or gases. The name “side channel” refers to the characteristic design of these pumps, in which the medium flows through side channels. This distinguishes them from conventional centrifugal pumps. Industrial side channel pumps are mainly used in applications with high pressure requirements and the need to generate pressure differences. Typical applications include vacuum technology, pneumatic conveying, sewage plant aeration, waste water treatment, compressed air technology, medical devices, textile processing, the food industry and environmental technology, where they offer high conveying performance and reliability.

Here are some important features and characteristics of our side channel pumps:

• Operating principle: Side channel pumps use a rotating impeller with specially shaped blades or vanes arranged in the side channels. The rotation of the impeller creates pressure differences in the side channels, which leads to the pumping or compression of the medium.
• Pressure differences: Side channel pumps are known for their ability to generate relatively high pressure differences. This means that they are capable of pumping liquids or gases at a higher pressure than many other pump types.
• Versatility: These pumps can convey or compress both liquids and gases. They are available in different materials to suit different media and chemical resistances.
• Self-priming: Side channel pumps are often self-priming, which means that they are able to draw in liquids from a low height or level without the need for additional pre-filling.
• Applications: Our side channel pumps are used in a variety of applications, including vacuum generation, compressed air conveying, aeration in wastewater treatment plants, wastewater treatment, food processing, chemical processes, surface coating and more.
• Compact design: They are often characterized by a compact design, which makes them suitable for use in confined spaces.
• Regulation: The delivery rate of side channel pumps can be regulated by the speed of the impeller, which offers a certain flexibility in adapting to different requirements.
• Two-phase delivery: Specialized in the efficient delivery of liquid-gas mixtures, ideal for a wide range of industrial applications.
• Performance data:
  • Flow rates up to 36 m³/h (600 l/min)
  • Delivery heads up to 350 m (35 bar)
  • Nominal pressures up to 40 bar
  • Temperatures from -40°C to +220°C
  • Speeds: 1450 rpm (50 Hz), 1750 rpm (60 Hz)
  • NPSH values up to 0.5 m
• Versatile modular system: Horizontal and vertical configurations, 1 to 8 stages, for clean or turbid liquids without solids.
  Effective sealing options: Available with packings, mechanical seals or seal-less magnetic drive.

The selection of a suitable pump depends on the specific requirements of the application, including the required pressure, flow rate, type of liquid or gas and chemical resistance.

Our single-channel pumps are used in various industries and applications where a medium to high pressure build-up is required. Due to their special design and capabilities, they are frequently used in the following areas of application:

• Vacuum technology: Side channel pumps are often used to generate negative pressure or vacuum in applications such as vacuum packaging machines, vacuum suction cups, vacuum lifting devices and analytical instruments.
• Pneumatic conveying: Side channel pumps are used to generate compressed air flows or vacuum systems in industrial processes in which powders, granulates or bulk materials need to be conveyed.
• Aeration in wastewater treatment plants: Side channel pumps are used in wastewater treatment plants to feed air into the aeration systems required for biological wastewater treatment.
• Waste water treatment: Side channel pumps can be used in industrial waste water treatment plants to pump waste water, process waste water or chemicals.
• Compressed air technology: Side channel pumps are used in compressed air systems to generate or compress compressed air that is required in various industrial processes.
• Medical applications: They are used in medical devices such as breathing air supply systems, blood pressure monitors and medical vacuum systems.
• Textile industry: Side channel pumps can be used in the textile industry for processes such as the application of dyes, the fixing of colors or the drying of textiles.
• Food industry: In food processing, side channel pumps are used to convey food ingredients, liquids and solutions in various processes.
• Wood and paper industry: Side channel pumps can be used in the wood and paper industry to generate air flows for drying or processing operations.
• Environmental technology: They are used in various environmental technology applications, including emission control, air purification and water treatment.
• Industrial cleaning: Side channel pumps can be used in industrial cleaning systems to pressurize water or cleaning agents.

The selection of the appropriate pump depends on the specific requirements of the application, including pressure, flow rate, medium, chemical resistance and operating conditions. Our side channel pumps offer flexible solutions for different needs and are ideal for demanding situations where the efficient pumping of two-phase flows is required.
