Overview

Senninger’s Smooth Drive™ is designed for under-tree, open-field and nursery irrigation. Its unique “walking diffuser” helps deliver an extremely uniform pattern that prevents dry areas caused by distortion from bracket legs.

Features

Low Angle model ideal for under-tree (white base)
High Angle model ideal for open-field (black base)
Precision-contoured deflector provides greater throw and enhanced distribution
Advanced braking mechanism for smooth, consistent rotation speed and minimal riser stress
No tools required for accessing nozzle
Connections: 1/2" M NPT, 1/2" x 3/4" socket x 1" spigot, or 22mm socket x 25mm socket
Solvent-weld socket base options offer theft resistance
Two-year warranty on materials, workmanship and performance
Color-coded nozzles for easy size identification. Warranted to maintain correct orifice size for five years

Advanced Features

Walking Diffuser

Ordinary rotating sprinklers have stationary legs that block water and create leg shadows (drier areas). The Smooth Drive's walking diffuser eliminates bracket leg shadows resulting in unobstructed, uniform distribution.

Pressure Regulators

Senninger® pressure regulators control excessive and varying inlet pressures to a constant outlet pressure. They allow a system to maintain an accurate flow output at each sprinkler head to ensure proper distribution uniformity.

Recognizing the importance of maintaining correct system pressure and uniform distribution, Senninger offers various models to meet specific flow and installation requirements.
