Side channel pumps (also known as turbine pumps) are hydraulic continuous-flow machines and a sub-type of centrifugal pump. They are classed as hydrodynamic pumps.

For decades now, Speck has been developing and manufacturing side channel pumps and completely revised the modular system of the SK and ASK model series in 2015.
