Sunfab SL Double Pump
The Sunfab SL double pump delivers exceptionally low noise levels in a slim, direct-mount housing. Available across eight sizes, with three differentiated-flow models offering small, large, and combined flow outputs for greater application flexibility — a cost-effective alternative to running two pumps with a splitter gearbox.
