K-RAIN ROTATOR SPRAY 3/4 INCH RPS75I W/ FLOW

A 3/4-inch gear-driven rotor sprinkler with integrated flow control, allowing proportional adjustment of water output and spray distance for efficient zone balancing.

The K-Rain RPS75 Rotator Spray 3/4 inch with Flow Control is a gear-driven rotor sprinkler designed for residential and light commercial irrigation systems. It is based on the standard RPS75 rotor platform but includes flow regulation capability, allowing the user to reduce or increase water output without changing nozzles.

This flow-controlled version enables proportional adjustment of both throw distance and flow rate, improving zoning flexibility and water efficiency. Instead of relying only on nozzle changes or arc restriction, the integrated flow control allows fine tuning of irrigation output directly at the rotor.

The standard RPS75 platform uses a patented reversing gear mechanism for smooth back-and-forth rotation and supports full-circle or part-circle operation. The flow-controlled variant enhances system balancing, especially in mixed zones where different sprinkler heads are used.

The rotor is compatible with K-Rain's full range of standard and low-angle nozzles, allowing matched precipitation across different spacing layouts. It is commonly used in turf areas, sports fields, and landscaped zones where adjustable output is required for uneven water demand areas.
