K-Rain Product Lines

K-Rain gear-drive rotors are known for a patented reversing mechanism built to keep turning reliably, even with dirty water. The line runs from the compact MiniPro and ProSport up to the PRO Plus, SuperPro, and the flagship RPS75, and most are arc-adjustable from the top.

K-Rain also makes electric solenoid valves and its well-known indexing valve, which sequences several zones from a single water source or pump. No electric controller required.

Buying guide

K-Rain rotor lines compared

Every K-Rain rotor shares the patented reversing mechanism. Match the line to your zone radius, then decide whether you need flow control or a drop-in retrofit for a Hunter PGP.

Model Radius Arc Key feature Best for
RPS75 / RPS75i22 to 51 ft40 to 360Universal riser fits a Hunter PGP or PGP Ultra can; RPS75i adds Intelligent Flow controlResidential and light-commercial turf; PGP retrofit
PRO Plus22 to 50 ft40 to 360Arc memory clutch, arc set from the topGeneral turf
Super Pro26 to 46 ft40 to 360Intelligent Flow cuts distance and flow together, up to 50 percentFull feature set with proportional flow control
ProSport43 to 77 ft40 to 360Triple nozzle for long throwSports turf and commercial fields

The RPS75 is the line most crews reach for, and its riser drops into an existing Hunter PGP can, so you can retrofit a failed rotor without cutting the swing pipe. Browse all K-Rain rotors, or step out to every rotor brand to compare.

K-Rain FAQ

What makes K-Rain rotors different?

K-Rain rotors use a patented reversing mechanism designed to keep turning reliably even with dirty water, and most are arc-adjustable from the top. The RPS75 is the flagship model.

What is a K-Rain indexing valve?

An indexing valve automatically sends water to a different zone each time the supply turns on and off, so one pump or water source can run several zones in sequence, without an electric controller. It’s a common choice for pump-fed and lake- or well-supplied systems.

Are K-Rain rotors compatible with Hunter or Rain Bird systems?

Yes. K-Rain rotors install on standard female-threaded risers and swing joints, so they drop into most existing in-ground systems alongside other brands’ rotors.

Can I adjust the spray arc on a K-Rain rotor?

Yes. Most K-Rain rotors adjust from the top, letting you set the arc (the sweep angle) and fine-tune the radius with the nozzle. No need to dig up the head.
