When it comes to high differential heads, gas-entrained liquids, and low-flow requirements, side channel pumps prove their worth as reliable and efficient hydraulic continuous-flow pumps.
The side channel pump fills the void between a centrifugal pump and a positive displacement pump; utilising its distinctive star impeller, fluids are energised and gas content is passed through channels. Available as either a mechanically sealed or magnetically driven unit, the side channel pump can be configured to your individual requirements with a variety of material options.
Side channel pumps are capable of handling gas entrained liquids with up to 50% inclusion with a temperature range of -20°c → +120°c as standard; with modifications capable of increasing the range significantly. The furrow along the impeller casing allows gas content to flow through without causing the pump to stall. Due to the modular design, we can have over 4800 mechanical variants which helps us become extremely flexible to your system requirements.
Side channel pumps offer a lot of advantages that make them a preferred choice for specific applications, including:
Side channel pumps excel in high-head, low-flow applications and can generate significantly higher pressures than other pump types of a comparable size and power. This makes them ideal for pumping liquids across long distances or through small pipework.
One of the standout features of side channel pumps is their ability to handle liquids with high gas content. They can efficiently pump fluids with up to 50% gas content, making them a reliable choice for applications involving condensates, LPG, and other gaseous liquids.
Side channel pumps are designed to be self-priming simplifying the installation process and reducing the risk of priming-related issues.
Net Positive Suction Head (NPSH) is a critical parameter in pump design, as inadequate NPSH can lead to cavitation. Side channel pumps have low NPSH requirements, allowing them to handle liquids close to their boiling point without the risk of cavitation.
Side channel pumps can handle liquids across a wide range of temperatures, from -60°C to 220°C. making them suitable for applications involving extreme temperature conditions, such as boiler feed systems and thermal oil transfer.
Side channel pumps are highly efficient in low-flow applications. They can deliver high differential heads even at low flow rates, making them more economical and energy-efficient.
The modular design of side channel pumps allows for easy controllability and adaptability to varying process requirements. They can be configured with multiple stages to achieve the desired performance characteristics.
Side channel pumps are available with various sealing options, including mechanical seals and magnetic drives.
The unique capabilities of side channel pumps make them suitable for some very specific applications:
1. Methanol for ship engines
2. Battery electrolyte handling
3. Carbon Capture Systems – When using Side-Channel Pumps in your carbon-capturing process, CO2 is captured, and then it goes through a compression stage where it is subjected to high pressure so that it can be transported as a liquid to its destination for use or storage. Methanol, Ammonia and Hydrogen fuel
4. Boiler Feed Systems where high temperatures and low flows are involved.
5. Condensate extraction can handle the high gas content often associated with condensate without the risk of pump cavitation.
6. The Liquid Gas Handling capabilities of side channel pumps can safely and reliably handle liquids with high gas content.
7. Tank Emptying – Side channel pumps efficiently empty tanks and eliminate the need for secondary priming devices.
8. Heating and Air Conditioning Systems – Side channel pumps are used for circulation, transfer, and boosting of hot water and refrigerants.
9. Reverse Osmosis by providing the necessary pressure to drive the filtration process.
10. Liquid Circulation including thermal oil transfer, refrigerant circulation, and hot water recirculation.
11. Chemical Processing in the chemical industry for transferring volatile chemicals, liquid gases, and other corrosive liquids.
When it comes to high differential heads, gas-entrained liquids, and low-flow requirements, side channel pumps prove their worth as reliable and efficient hydraulic continuous-flow pumps.
