Mix and Match

We want to provide our customers every option possible, so we’ve come up with two ways to order. You can order using our “Mix and Match” method or select a pre-packaged pump with a switch included. This allows you the ability to have not only the quality pump you need but, the features and technology you want to go with it.

Option 1: Mix and Match – Order a pump and a switch as separate items

  • The pumps and switches are purchased as separate items, then combine to complete the system to meets your wants and needs
  • Best way to allow for many options
    • Select a pump, based on capacity, warranty or build materials
      • Example: the S3033-NS, a 5 year warranty, high capacity pump with No Switch
    • Then, select a switch to pair with it based on the features
      • Example: the DFC2, a Dual Float Switch with Deluxe Controller that has lights, alarms and when paired with a PS-WiFi can send text, email or in-app alerts

 

 Option 2: Pre-Packaged System – Order the pump and switch together in one box

  • Order any pump with the switch already packaged in a single carton, ready for delivery
    • Example: The S2033-VSC2, is a 4 year warranty, all cast iron pump and Vertical Switch with Deluxe Controller that has lights, alarms and when paired with a PS-WiFi can send text, email or in-app alerts
