Summary The side channel pump, which is a common energy conversion equipment, has undergone high developmental trends and has become very popular in recent times because of its wide applications in many fields. The side channel pump is a type of regenerative pump that plays a role in between the centrifugal pump and the positive displacement pump. This kind of pump delivers a high head at relatively small flows compared with other axial and centrifugal pumps even though it requires a low specific speed. Depending on the number of impellers used, the side channel pump can be single‐stage or multistage. This paper first focuses on the physical principle behind the internal flow characteristics illustrating the complex flow and the energy from the blade to the fluid and the side channel inside the pump. Further discussions disclosed that the hydraulic performance of the pump greatly depends on the variations of the geometrical parameters. This review draws conclusion that enhancement of the computational modeling techniques will improve the efficiency of this pump, thereby broadening its applications.

“…Their inherent ability to provide multi-staging using only one impeller provides much higher heads compared to machines of similar tip speeds [13,15]. The head rise can be increased even further by incorporating several pumping stages on a common shaft [11].…”

“…Perhaps what really distinguishes the RLR pump is its ability to develop high heads at relatively low flow rates in only one impeller stage [7][8]. It shares similar operating characteristics to another pump classification, positive displacement: the power is directly proportional to head, with a maximum power required at shutoff and a very steep, nearly straight head-capacity curve [4,[9][10][11].…”

“…RLR pumps are also sometimes referred to as peripheral, side channel, water-ring, liquid-ring, drag, turbine, traction, tangential, vortex and claw-type pump in literature, often reflecting a variation in geometrical design or preference for a theory of the principle of operation [9,[12][13]. Figure 1 shows a schematic of a generic RLR pump.…”

The regenerative liquid ring (RLR) pump is a type of rotodynamic machine which has the ability to develop high heads at relatively low flow rates in only one impeller stage. Although the exact principle of operation of this type of pump has been a phenomenon not fully understood, it has nevertheless been widely applied for over a century in areas of liquid pumping. Despite the low efficiency, RLR pumps have several advantages over other turbomachines with similar tip speed due to relatively low manufacturing costs, simplicity, high reliability, enhanced priming behaviour and can in many applications offer a more efficient alternative. Efficiency improvements are key to reducing energy consumption and ultimately combatting the global climate change. This paper offers an extensive review into the development, performance challenges and design improvements of RLR pumps in order to provide some useful insight on future research and next steps, with a particular focus on improving efficiency throughout the pump life cycle.

“…Quil et al used a commercial code to investigate the fluid flow in a regenerative pump. They also carried out a new method of manufacturing to evaluate the influence of change in blade geometry on the efficiency of regenerative pump [11,12]. An experimental study was accomplished by Choi et al to investigate the effect of the impeller blade angle and its shape on regenerative pump performance.…”
