Iota 20GR3 4 25GR3 4 Series@2x 1

The IOTA 25 GR3/4 shares the IOTA 20’s compact 12 lb frame and 3/4 inch petrol gear reduction drive, but lifts flow to 24 L/min (7.0 GPM) while holding the same 20 bar (300 PSI) pressure at 600 RPM. That extra flow suits slightly larger spot sprayers and misting setups without stepping up to a bigger, heavier pump. Like the rest of the IOTA line it uses a 4–6.5 HP petrol engine shaft, making it an easy self-contained upgrade from the IOTA 20.
