Liquid Chlorine Pump

[IASteve]

I currently have a 3" tri-chlor clorinator. My CYA levels have climbed from 0 at opening to 70 now at the end of the season. I'd like to get a liquid chlorine pump.

Does anyone have any recommendations on brands or models?

Thanks,

Steve

I think my thread will,answer most of your questions. My Stenner Install - July 2014

It cost a little more, but Stenner makes a really nice thank that the pump mounts to. I think it's 15 gallons.

This looks like something I'd like to do. I was looking at the Rota-Flow. It has a built in timer to accomplish varying feed rates.

How loud is the Stenner when it 'pops' and how often does it do it? Also, how often do you have to service them?

The stenner is not really a quiet device. It sounds like a geared electric motor, like a radio controlled car but at a lower pitch. The clicking varies based on the setting. Mine clicks once every 3-4 seconds I think. I installed mine in my basement. I do not have any insulation between my basement and the first floor, and I can hear the device and the clicking, but it isn't noticeable enough to be annoying.

I have my Stenner set to full flow, so the ratcheting device doesn't kick in.
Mine just makes a steady hum while it works.
I control it with the timer alone... I can set my timer to the minute.

I made my own LC injection system with peristaltic dosing pumps from eBay or Amazon and a garage sale Genie sprinkler timer. I added a 5-gallon jug, some tubing, fittings, etc. and it's been working great. It all sits in my shed next to the pump and filter.

I enjoy such DIY projects but you might prefer the well-proven Stenner option.

I went with the Rola-Chem pump, the 12gpd model. And I just wired it up through a relay on the water pump and a timer dedicated to the Rola-Chem. I went with the Rola-Chem just because a local store had them and I was pretty excited to get my auto liquid chlorine feeder working. It's been working great, no problem yet. I'm surprised to hear about this noise from the Stenner's, the rola-chem is very quiet but I don't think a little noise would bother me enough to not buy a stenner.

From my experience, I definitely recommend going this route of using a liquid chlorine feeder with peristaltic pump. And I think you'll be happy with either a Stenner or Rola-chem.

I see you already are running an Intermatic timer on your pump. If you go with a Rola-chem, I'd recommend using the Digital Intermatic timer with it because of the way the Rola-chem works on a 9 minute timer pot.

I've been thinking about this - I know it wouldn't be hard. We sell peristaltic and service peristaltic pumps in a separate division at work - I thought about trying to get one for free. Might end up going this route.

Mine would be in a pool house. I'm a little turned off by the indexing noise. How loud is the loudest and normal click level? Hearing it through different house levels seems like it would be fairly loud.

It is not that loud. I can only hear the clicking and only from the room directly above it. Similar to hearing the central air unit kick on.

In a pool house it will be just fine. I doubt you would hear it any more than 20' away. The filter pump would most likely down it out anyway.

If it bothers me next year then I will just cover it with some rigid insulation to block the sound.

This is the pump I'm using. I first began with the cheap $12 "disposable" pumps but I saw this one and liked the features and construction. They say the main parts and pump are made in the USA but I know the 12VDC motor is from China. It uses Norprene tubing but comes with all kinds of tubing material choices. Correcvt replacement tubing is available from the same company and not expensive. Norprene has a very long service life compared to many other tubing options. The pump uses a brushed, single speed motor and you can adjust the run time to adjust the delivered liquid but I also use a PWM as a speed control because I happen to have them for my LED projects.

As I said, I like to tinker and enjoy making my own projects like this. The Simply Pumps site is full of data sheets, drawings and tubing info if you enjoy geeking out on the pumps.

A fixed rate stenner pump is cheaper than the adjustable rate stenner and has fewer moving parts to maintain. Dosage amount is controlled easily with a timer and the pump only needs to be run a short time each day. I have a 10 gal/day stenner on my pool and it only needs to run 45 minutes of each 24 hours. The timer is set to run the pump in two doses, 15 minutes at noon and 30 minutes at 5pm. The motor is not silent but the pump does not really run long enough to bother and it can be set to dose any time of day that is convenient for you. My pump and reservoir is installed back in the utility room of my basement, I really never hear it. For a larger pool you could choose to install larger capacity pump tubes to keep run time at a minimum.

This is where I got mine,
