Submersible Glycol Pump — 12V DC (3/8" Barb) ❄️

Simple, reliable glycol circulation for precise fermenter temperature control.

These submersible glycol pumps are designed to work with glycol chiller setups where you want individual temperature control per fermenter. The common best-practice is one pump per vessel—each pump plugs into its own pump controller, and that controller turns the pump on/off based on the fermenter’s temperature.

Meanwhile, your glycol chiller regulates the reservoir temperature so there’s always cold glycol ready to circulate when a fermenter calls for cooling.

How it’s typically used ✅

• 1 pump per fermenter/vessel

• Each pump plugs into a glycol pump controller (controller monitors fermenter temp and cycles the pump)

• Run multiple fermenters independently off the same chiller reservoir—each with its own setpoint

Why this setup rocks

• Independent control per fermenter (different beers, different temps)

• Clean installs with a straightforward 3/8" barb outlet

• On-demand cooling: pump only runs when the controller calls for cooling

• Scales easily: add another pump + controller when you add another vessel

Pump Specs

• Voltage: 12V DC

• Power: 19W

• Max Flow: 3.5 GPM

• Max Head Height: 16 ft

• Outlet: 3/8" barb fitting

Notes (important) ⚠️

• Controller not included (pump is typically controlled by a separate pump controller per fermenter).

• For best performance, ensure the pump is fully submerged in the glycol reservoir and don’t run it dry.
