K-Rain RPS 75 Rotor 4 in. (Case of 20) | RPS75-CASE20

Product Overview

Mid-season rotor failures and uneven coverage can quickly turn a profitable landscape project into a series of unpaid service calls and frustrated clients. When the summer heat peaks, your crews cannot afford to wait on back-ordered inventory while turf sections begin to brown or high-value plantings suffer from water stress. Ensuring you have a full case of reliable rotors on the shelf means you can avoid the time pressure of local supply shortages and the logistical headaches of last-minute sourcing. Planning your inventory with a bulk case purchase ensures your projects stay on schedule and your client inspections pass without a hitch.

The K-Rain RPS 75 provides a direct, high-performance replacement for the industry standard Hunter PGP, allowing your crews to swap out heads without needing to rework the existing piping or system layout. This rotor features a patented reversing mechanism that ensures continuous reverse and return, which significantly reduces the mechanical wear often found in lower-grade alternatives. By choosing this professional-grade gear-driven rotor in bulk, you save on the per-unit cost while reducing long-term maintenance labor for your clients. Maintaining a well-stocked shop gives your business a competitive edge by allowing for immediate response times and consistent installation quality.

Installation Notes

Install the RPS 75 on a standard 3/4 inch swing pipe or triple-swing assembly to prevent riser breakage from foot traffic or mower impact. Ensure the head is installed flush with the finished grade to meet safety requirements and prevent tripping hazards. When adjusting the arc, use the top-access adjustment port to set the fixed left start and the variable right stop according to the site plan. Always flush the lateral lines before installing the nozzle to prevent debris from clogging the internal filter screen or the gear drive assembly.
