The original Flojet Duplex Series pumps were built for intermittent duty with freshwater or dispensing systems (without particulate) such as fountains and syrups, coffee, tea or alcohols. The Duplex 2 Series built on this success and expanded to include washdown, marine, automotive and RV applications with drinks, spraying, mild chemicals and general purpose. All models offer Run-Dry ability as well varied UL, CSA and CE certifications (varies by Model). Select Models have a variable pressure switch.
All Duplex Series units have a direct match replacement with the Duplex 2 Series - See cross-reference details.
The Triplex Series does NOT match directly with the Duplex models; Check your specifications and requirements on that Product page.
