Centrifugal pumps are designed for optimal operation in their design point, i.e. at one determined pressure head and specific flow rate. Away from this design point, their efficiency drops rapidly. In windpumps, piston pumps are much more common than centrifugal pumps since their efficiency is less sensitive to fluctuations in head and speed.
