K-Rain RPS 75i Rotor



The RPS 75i rotor is designed for residential and light commercial applications. This new addition to K-Rain’s line of rotors retains all of the features and benefits of the RPS75™ and delivers even more! To reduce the radius and distance in other rotors on the market, the nozzle must be changed or the break-up screw must be engaged. These steps limit the maximum reduction to 25% and cause uneven watering. With the RPS 75i, a simple turn of the patented Flow Shut-Off controls distance and water flow proportionately—up to 50%. The RPS 75i delivers even water distribution, eliminates dry spots and provides better zone performance while saving water. All of this in just one rotor—the right rotor for every landscape!


 The most cost-effective solution on the market, the RPS75® gear drive is high quality, durable and reliable sprinkler designed for basic residential and light commercial applications.   A direct replacement for the Hunter PGP® rotor, with our  time-proven, patented reversing mechanism (the same used in the Hunter PGP®), the RPS75® drops directly in an installed Hunter PGP® can.

The RPS75 gear drive is designed for basic residential and light commercial applications and is a direct replacement for Hunter® PGP® rotors. The reversing mechanism, a K-Rain patented feature, is the same mechanism used in the Hunter® PGP® (K-Rain currently licenses this patent to Hunter® - U.S. Patent No. 5,417,370 Carl L.C. Kah Jr.). With K-Rain's wide selection of standard and low angle nozzles, the RPS75 provides even water distribution.
