Hunter PSR22 Pump Start Relay – Up to 5 HP (Double Pole or Single Throw)

Overview

In irrigation setups that rely on booster pumps or pull water from a creek or pond, a dependable pump-start relay can make irrigation run more smoothly. The Hunter PSR22 is engineered to activate the pump precisely when your sprinkler controller calls for water, helping maintain consistent pressure across zones and reducing the need for manual adjustments.

How it fits into your irrigation system

The PSR22 serves as a bridge between your irrigation controller and the pump. When a zone signals for water, the relay completes the control circuit to the pump, initiating operation smoothly. This can be especially helpful for setups with higher lift, remote water sources, or booster pumps designed to reach distant zones.

Wiring is designed for straightforward integration with standard 24V control lines from typical irrigation timers, aiming for a clean, reliable installation.

Real-life scenarios

Imagine a landscape that relies on a pond as a water source. The PSR22 can start the pump automatically as soon as the controller calls for water, helping to maintain steady system pressure and uniform zone performance. For 230V pump configurations, the relay provides a dedicated activation point that adapts to varied site conditions and power layouts.
