best calcium reactor feed pump

[oscarsdad608]

I have been running mine off of my return pump manifold and I can't keep a constant drip rate to save my life.
If I can't get a constant drip rate I am going to go to dosing pumps but I really don't want to change everything.
Please let me know what pump you are using and your opinion on it.

Cole-parmer masterflex peristaltic pump.

You remove the needle valve and adjust the speed of the pump and size of the tubing to determine the flow rate. It is 100% consistent regardless of the amount of media in the reactor.

The easy load heads are what you want. They are stackable so as your demand increases you can increase the number of pump heads to keep rpm slow. This increases tube life.

They are not cheap but worth it. Check out ebay.

Do you set your drip rate on the feed to the reactor or the output?

I have it before and after. I think I might try to find a plastic needle valve instead of a ball valve.
Does anyone have suggestions on what valve to get?

Flow is so slow through a Ca reactor I do not dedicate a pump. Consider just adding a tee to tour return line with a ½" valve, and then run your tubing to the reactor. Use a small inexpensive needle valve on the outlet to adjust the flow to a steady drip or slow flow, depending on demand

I am using a maxijet 600 to feed my reactor
