Hi,
I am building a hot tub and have a question about electrocution risks. I have the option to use a 120v AC pump and a 24v DC pump, where wattage/power would be the same on both pumps. The spa tub is made from metal (don't ask why) and the tub itself is grounded. These pumps have all the...
Thank you for the additional info.
I have the option to not run the pump 24/7. Instead, I could run it for 4-8 hours per day. This would decrease total hours run by 75%, but introduce 365 start/stops per year. Which would you prioritize for pump longevity?
Hi,
I'm designing a ice bath water filtration system and need some advice on length of filtration cycles. Here is some background:
- Filtration system consists of a pump, filter, and venturi injector for ozone.
- System Q = 4000 l/hr.
- Ice bath holds 500 liters of water.
- Water is between...
Thank you for your replies. To expand a little more - the pump needs to have a flow rate of around 10,000 l/hr.
I think it's an interesting point that lower specific speed and less efficient pumps last longer. Right now I could use a 24VDC centrifugal brushless pump that consumes about 80w...
Hi,
I'm designing a cold plunge filtration system and looking for some advice on pump types. The system design is as follows:
cold plunge -> hair filter / catcher -> pump at floor level -> water filter + venturi injector -> exhaust
The pump will be running 24/7 and my priority is to make the...
