Side Channel Pumps

Side channel pumps fill the gap between centrifugal and positive displacement pumps. Using a distinctive star impeller, fluids are energised while gas content passes through channels without causing the pump to stall. Available as mechanically sealed or magnetically driven units with various configurations and material options.

These pumps can handle gas-entrained liquids with up to 50% inclusion at temperatures from -20°C to +120°C as standard, extendable to -60°C to +220°C with modifications. The modular design offers over 4,800 mechanical variants for flexibility to suit your system requirements.

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.
Self-priming suction lift of up to 8.5m

Low Net Positive Suction Head (NPSH) – operates with as little as 0.35m and handles liquids near boiling point without cavitation

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
Mechanical seal and magnetically driven options

Common Applications

Methanol for ship engines, battery electrolyte handling, carbon capture systems, boiler feed systems, condensate extraction, liquid gas handling, tank emptying, heating and air conditioning systems, reverse osmosis, liquid circulation (including thermal oil transfer, refrigerant circulation and hot water recirculation) and chemical processing of volatile chemicals, liquid gases and other corrosive liquids.
