Pulsar 4KHP Unloader, 10.5GPM, 4050PSI, Blue Spring

This compact pressure regulating unloader is designed for single gun or pump operation and nozzle application. This is pressure sensitive and permits a wide range of flows and immediate pressure when the trigger gun opens. We recommend this unloader for intermittent cleaning applications. We don’t recommend using this for weep systems or in below freezing temperatures. For optimum performance, 5-10% by-pass is necessary. It is compact in size with optional ports to aid with an easy installation.
