Reactor Feed Pump

Just be sure to put the ball valve before the reactor and not after when doing it this way. I found out the hard way you can pressure up a reactor really nicely (and maybe pop a seam or two) if you try to control the flow on the effluent side as opposed to the input side. I didn't think the head pressure of the sump return was as bad as all that but apparently it was.

Nowadays I just use minijets to feed my reactors and a needle valve on the effluent. The minijets don't put out so much pressure to worry me, they're inexpensive (and who doesn't have a half dozen of them lying around anyhow, finally a way to use them up!!).

I thought about a peristaltic pump for a reactor feed maybe, but it looks like you can't really control the speed of those (they're either on or off) -- at least the one I tried didn't have variable flowrate control.

If you really wanted to get funky, how about a dosing pump? Hey, didn't you buy Chad's dosing pump there Deb?
