Side Channel Pumps
Side channel pumps fill the gap between centrifugal and positive displacement pumps. They are available as mechanically sealed or magnetically driven units with various configurations and material options. Their modular design gives thousands of combinations.
Key features:
• High differential head – ideal for pumping liquids across long distances or through small pipework
• Handles high gas content (up to 50%) – a reliable choice for applications involving condensates, LPG, and other gaseous liquids
• Low Net Positive Suction Head (NPSH) – operates with as little as 0.35m and handles liquids near boiling point without cavitation
• Self-priming suction lift of up to 8.5m
• Wide temperature range – from -20°C to +120°C as standard, extendable to -60°C to +220°C with modifications
• Efficient and economical in low-flow applications – suited to applications as low as 0.4m³/hr
• High pressure – up to 40 bar (8-9x higher than centrifugal pumps)
• Easy to control head and flow due to steep operating curves
• Handles low viscosity fluids
Materials of construction:
• A wide range of options including casings manufactured in ductile iron, super duplex SS, stainless steel AISI 316 and bronze
• Hastelloy and carbon fibre reinforced polymer containment shells on magnetically driven pumps
