Description

Your sprayer pump working intermittently? Kicking on and off at random times? A worn pressure switch is usually the culprit when your Shurflo pump won’t cycle properly. This replacement pressure switch is what tells your pump when to start and stop based on system demand—when it’s working right, you get consistent pressure and smooth operation every time you pull the trigger.

What You’re Getting

  • Santoprene construction resists chemicals and handles temperature swings without cracking
  • Factory-calibrated pressure settings ensure reliable on/off cycling for your pump
  • Direct replacement design means no rewiring or modifications needed
  • Built to handle the vibration and rough conditions of agricultural spraying

Built for Real Farm Work

This pressure switch is designed for Shurflo demand pumps commonly used in spot sprayers, tank sprayers, and wash-down systems around the farm. Whether you’re spraying weeds along fence lines, applying herbicide to field edges, or washing down equipment, this switch keeps your pump cycling smoothly when you need it.

Made to Last

The Santoprene material is specifically chosen for its chemical resistance and durability in agricultural applications. It won’t crack from exposure to common herbicides, fertilizers, or temperature changes like cheaper rubber components do. The internal contacts are designed to handle the electrical load of pump motors without premature failure.

Installation Notes

Most installations are straightforward—disconnect power, unscrew the old switch, and thread in the new one. Make sure connections are clean and tight. If your pump has been cycling erratically, it’s worth checking system pressure and cleaning any debris from spray tips while you’ve got things apart.
