R55 End of Pivot Sprinklers

R55 End of Pivot Sprinklers

Flow: 20-105 gpm (4.2-23.6 m3/hr)

Pressure: 15-60 psi (1-4 bar)

Radius: 40-56 ft (12.2-16.9 m)


The new Nelson R55 VT uses a patented variable torque speed governing system that allows the plate to maintain a constant rotation speed across a broad range of nozzle sizes and pressures. This constant rotation speed results in maximum radius of throw - up to 56 ft (16.9 m).

The latest generation of the R55 also incorporates snap-fit nozzles, eliminating the need for a retaining pin to secure the nozzle to the sprinkler body. The sprinkler threads are integral with the nozzle, and are available in 1 1/4" MNPT or MBSP.

The inverted R55i VT, with a specifically engineered green plate, is easier to install and is effective in helping flush debris that collects at the end of the system.  

Pick up added acreage both throughout the full revolution of the pivot or just in the corners, depending on site specifics and irrigator preferences. Use independently or in conjunction with a higher volume Big Gun® Sprinkler.
