Side-channel pumps

Industrial side-channel pumps are a specialized type of pump used in industrial applications to convey or compress liquids or gases. The name “side-channel” refers to the characteristic design of these pumps, in which the fluid flows through lateral channels. This distinguishes them from conventional centrifugal pumps. Industrial side-channel pumps are primarily used in applications requiring high pressure and the creation of pressure differentials. Typical applications include vacuum technology, pneumatic conveying, wastewater treatment plant aeration, wastewater treatment, compressed air technology, medical devices, textile processing, the food industry, and environmental technology, where they offer high flow rates and reliability.

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

• How It Works: Side-channel pumps use a rotating impeller with specially shaped vanes or blades arranged in the side channels. The rotation of the impeller creates pressure differentials in the side channels, which results in the conveyance or compression of the fluid.
• Pressure Differences: Side-channel pumps are known for their ability to generate relatively high pressure differences. This means they are capable of pumping liquids or gases at higher pressures than many other types of pumps.
• Versatility: These pumps can transport or compress both liquids and gases. They are available in a variety of materials to accommodate different media and chemical resistance requirements.
• 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 flow rate of side-channel pumps can be regulated by adjusting the impeller speed, which offers a certain degree of flexibility in adapting to various requirements.
• Two-phase pumping: Specialized in the efficient pumping 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
  • Speed: 1,450 rpm (50 Hz), 1,750 rpm (60 Hz)
  • NPSH values up to 0.5 m
• Versatile modular system: Horizontal and vertical configurations, 1 to 8 stages, for clear or turbid liquids without solids.
  Effective sealing options: Available with packing, 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 side-channel pumps are used in various industries and applications where medium to high pressure is required. Due to their special design and capabilities, they are frequently used in the following areas:

• 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 applying dyes, fixing colors, or drying 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 airflows 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.

Selecting the right pump depends on the specific requirements of the application, including pressure, flow rate, fluid, chemical resistance, and operating conditions. Our side-channel pumps offer flexible solutions for a variety of needs and are ideal for demanding situations that require the efficient handling of two-phase flows.
