Overview

The Senninger® PSR™2 is designed to handle flows from 0.5 to 15 gpm (114 to 3407 L/hr). Its patented design makes it ideal for center pivot systems using surface water.

Features

Senninger irrigation water pressure regulators maintain a constant preset outlet pressure with varying inlet pressures, which alleviates pressure differences that can cause an applicator’s area of coverage to change.
100% pressure tested, to ensure quality and performance
Very low hysteresis and friction loss
Two-year warranty on workmanship, materials and performance

Advanced Features

SennREG App

SennREG is a handy tool to bring into the field when checking your pressure regulator’s performance. With just a few clicks, you’ll know exactly what to expect out of your pressure regulator – from what your output pressure should be, to when you should start thinking about replacements.
