Discharge Chamber 1.5in ONLY - Side Inlet - Bronze & Aluminum - 18 &30 GPM

A direct replacement for the Discharge Chamber Edson Side-Inlet(only) Pump bases. These are the 1.5" diameter chambers ONLY. You can choose based on the size of the pump you have, and the diameter of the threaded hose port. Please note that the bolt pattern for the two different sizes will not match up, so it's important to make sure you get the correct version based on your pump size. Available in either Bronze or Aluminum.

If you are unsure of which one you have, you can confirm the correct part using the casting number on the side of your current pump. Please note that these bases must be paired with the same metals used in your suction/discharge chambers, or metallic corrsosion will prematurely age and wear out both pieces.
