The Pro Chiller Water Pump is a 24V brushless circulation pump built for cold plunge chillers and DIY cold plunge builds. It moves up to 270 gallons per hour on just 35 watts, runs quietly around the clock, and works either inline outside the tub or fully submerged inside it. Choose 3/4" or 1/2" male NPT ports to match the plumbing you already have.
Note: This is not a water pump replacement for a Gen 1 Plunge. If your Gen 1 Plunge water pump is not working take a look at our Gen 1 Plunge Water Pump Replacement Kit.
Which port size do I need?
Match the pump to the threads on your existing plumbing so it installs without adapters.
| Port size |
Threads |
Choose it if |
| 3/4 Inch |
3/4" male NPT inlet and outlet |
Your chiller plumbing runs 3/4" lines, including the Cold Plunge Chiller Pro and most standard chiller setups |
| 1/2 Inch |
1/2" male NPT inlet and outlet |
Your cold plunge uses 1/2" plumbing, which is common on many tubs and chiller systems |
Not sure? Check the threads on the pump you are replacing or the fittings it connects to. Both sizes are the same pump with the same performance; only the ports change.

Power it from your chiller or on its own
In a typical setup the pump draws power from the chiller's integrated pump power. When you want circulation without the chiller running, such as during winter when the chiller comes inside, during a water change, or while bench testing a new build, both port sizes run on our 24V Power Adapter. Plug it into a GFCI-protected outlet and your water keeps moving through the filter.
Built for continuous duty
The brushless motor is designed for 24/7 operation without the brush wear and noise of traditional brushed pumps. Whether you are replacing a failing pump or building a custom plunge system, it delivers the steady flow your chiller and filter need to hold temperature and keep water clear.
Installation tips
- Wrap the male NPT threads with thread seal tape before connecting to prevent leaks.
- Running 3/4" ports? Add our 3/4" Quick Connect to 3/4" Female NPT fitting to each port and the pump disconnects in seconds for service or draining.
- If you mount the pump submerged, keep the power connection and adapter outside the tub in a dry location.
