120 VAC Dosing Pump?

[davthomaspilot]

I need to replace one of my dosing pumps, maybe both.

They are 24V pumps from an Intellichem setup, but now driven from a relay card on an rpi.

The Econ series from Stenner will fit on the 15 gallon tanks I have, but they are 120 VAC.

Has anyone used those with an SSR or maybe a Z-wave or Zigbee AC outlet?

Alternately, anyone have a suggestion for a 24V dosing pump? Or, a 120V AC pump that has an SSR that could be controlled from the 24V output sfrom the REM box?

Turns out the Econ FX series come in both 24v and 110 VAC versions.

Found the 24 volt version on EBAY and ordered 2.

The rep at Stenner says the check valves are needed for these pumps and should be removed. One less thing to replace each year I guess

Little late for you now, but I had originally ordered the 120 v Econ FX, only to find that I could not use them as I had wanted to and that I needed the 24 VDC. I removed the transformers inside the Stenners, added a switch, snubber, and wired 24 VDC from my relay. Power to the relay was provided by another transformer. For check valve on the acid injection I went with the Stenner Ball Check Valve - 1/4" Tantalum Spring (FKM) which should last a good long while.

Thanks for the update--mine should be here this afternoon.

I already have the 24V supply, since that's what I was running the Intellichem dosing pumps with. I think the Intellichem are the same pump as the Econ Series (24V version), just in a different enclosure designed by Pentair to mount on their tanks.

The Stenner rep said I didn't need a check valve and that I shouldn't use one. He said it would just clog eventually and have to be replaced. (I can confirm that I have to change them yearly))
