Brand: K-Rain SKU: 11003
Product Overview
The K-Rain 11003 ProPlus is a 4-inch adjustable-arc and continuous-full-circle gear-driven rotor for residential and light-commercial turf irrigation. Its 2-in-1 arc system can be set from 40° through continuous 360°, allowing one rotor model to serve perimeter, corner, interior, and full-circle locations without changing to a separate fixed-full-circle body.
Current K-Rain specifications list an approximate 22- to 50-foot radius, 0.5- to 10.0-GPM flow range, and 20- to 70-PSI operating range. The 3/4-inch female NPT inlet fits common residential rotor connections, while interchangeable standard and low-angle nozzles allow the installer to match flow, trajectory, and precipitation to the site. Clearly marked arc settings and top adjustment support wet or dry field setup.
An arc-memory clutch helps protect the internal gear drive if the turret is forced beyond its set stop and returns the rotor to its original pattern. The ratcheting riser makes it easier to reposition the left starting point, and the rubber cover helps keep dirt away from the adjustment area. Optional check-valve components are available where low-head drainage must be controlled; do not assume multiple check valves are included with a single rotor.

Compatibility and Installation Notes
Choose nozzles from measured dynamic pressure and available zone flow. Use matched precipitation rates, head-to-head spacing, and the shortest practical radius for the layout. Install the body level with finished grade, flush the line before inserting the nozzle, and use the correct K-Rain adjustment tool. Do not force the turret as a substitute for proper arc adjustment.
Frequently Asked Questions
Can the same rotor operate as part circle or full circle?
Yes. The ProPlus 2-in-1 design adjusts from 40° to continuous 360°.
What does the arc-memory clutch do?
It helps protect the gear drive if the turret is forced and returns the rotor to its set watering pattern.
Is a check valve included?
No individual check valve should be assumed unless the selected configuration specifically states that it is installed.
