The IOTA 20 GR3/4 is one of the smallest pumps in Udor’s diaphragm range, weighing just 12 lbs while still running a full 3/4 inch gear reduction drive for a 4–6.5 HP petrol engine. At 600 RPM it moves 19 L/min (5.0 GPM) at up to 20 bar (300 PSI), enough for compact spray carts, spot spraying and misting jobs where a full-size DELTA or ZETA pump would be overkill. Its small two-diaphragm design keeps the unit light without sacrificing the durability of Udor’s larger pumps.
