Masterflex L/S Compact as Calcium Reactor Feed Pump

SoloGarth · 11/12/2013, 02:32 PM

So after much research and after speaking with Cole Parmer I have decided that I will likely go with the Masterflex L/S Compact pump to feed my calcium reactor. I have been running it with various other non peristaltic feed pumps and have decided that I, at least, cannot maintain a stable effluent that way.

Here is the pump.

http://www.coleparmer.com/Product/Ma...DC/EW-77200-12

It is rated for 2.1 to 560ml per minute and is a much smaller form factor than the other continuous duty peristaltic at approx. 5"x5"x5". Also it is cheaper than the rest of the masterflex units which is an added bonus considering the price of these pumps. I am undecided as to whether to go with the DC or AC version.

Before I go ahead and buy this I thought I would see if anyone has any thoughts about why I should go with something different.

Thanks

Just wanted to update this in case anyone is interested.

I did purchase the Masterflex Compact Drive pump. I am running it with a standard L/S 16 Stainless pump head from EBay. The pump is nearly silent and is completely drowned out by my skimmer (deltec ap600) sitting across the sump. It did take a few days to break in and was a little noisy during that time but that's fairly normal.

L/S 25 would likely be a better option for this pump feeding a calcium reactor and I intend to switch over to that as demand increases.

Having this feed the reactor has allowed me to finally get a firm control of my alkalinity and lets me dial it in very easily. Expensive but worth it and all told it cost only a little more than an MP40.

Link doesn't work on my end but that could be my browser, tagging along.

Let's see does this work?

Ok here is the other

I have also ordered another larger masterflex pump that I am attaching 2 heads to in order to do a continuous slow water change.

Thanks for sharing. Which pump head did you go with?

I am using the standard stainless steel pump head part number 07016-20. This is working alright but my suggestion for a better option would be L/S 25 with easy load or standard pump head. The goal being to keep pump RPM at a minimum. See link below for pump flow rates.
