Questions & Answers
Is this a genuine original part?
This is a premium Seaflo brand pump, a leading global manufacturer of marine and RV water systems, backed by a 4-year limited warranty.
How do I know if it is compatible?
Check your existing pump's voltage (must be 24V) and flow rate. This model uses standard 1/2" MNPT connections which are common across Jabsco and Flojet systems.
What is the benefit of the "Internal Bypass" feature?
The internal bypass allows the pump to recycle a small amount of water within the head when demand is low. This significantly reduces rapid "cycling" (clicking on and off), leading to a much quieter operation and longer motor life.
Note: Please verify your system voltage is 24V DC before purchasing. For 12V applications, please see the 12V 33-Series model on 4boats.co.uk.
