Rainbow - Heavy Duty Tractor P.T.O. Driven Centrifugal Pumps

Rainbow Manufacturing Company's heavy duty tractor P.T.O. driven centrifugal pumps are designed based on more than four decades of pump engineering expertise. These robust pumps are engineered to connect quickly to conventional 540 RPM tractor power take-offs with a 1 3/8 inch, six-tooth spline or a 1000 RPM take-off with a 1 3/8 inch, 21-tooth spline. The series offers a broad range of capacities from 250 to 2100 GPM at pressures spanning from 90 to 200 PSI. Constructed with heavy-duty steel frames suitable for Category II and III three-point hitches or two-wheel trailers featuring 4.80 inch x 12 inch tires, the pumps are equipped with a P.T.O. drive shaft, an industrial strength gearbox with an expansion chamber, and a mechanical shaft seal. The gearbox is designed to handle loads up to 175 HP, compatible with both 540 and 1000 RPM drives.
