I'll go with any of the brushless models (quiet and zero maintenance). I got a 7551-00 and a 7522-20. Both are remotely controlled by the Apex varspeed outlets. The nice thing with these is that your can change the scale of the remote [that is, you can set in the MF unit what speed 0 volt is what speed 10 volt is]. I use one for continuous water change (with a two-channel head) and one for the calcium reactor.
I got both on ebay. It took some tenacity and thick skin (for making low bids), but I got one for $600 and the other for $350. |

77301-22 with long jumps
I am new with the masterflex.
I have the 77301-22 with engine 77301-21, from 10 to 600 rpm. At the moment I am trying to configure it and I realize that the increments are 10 ml .. When you put the measure of tube 17, it says 30 ml. in the display. until then everything normal, but trying to increase it goes to 40, 50, 60 and so on, I need 45 ml. Is this normal or is something missing in the configuration? I thank you in advance for the help you can give me with this topic. thank you |

That said, the flow rates will be limited to the head model, RPM adjustablity of the motor/controller and the tubing you are using.

If using LS17 Tubing, each revolution is 2.833ml. 16RPM will give you 45.33ml/min

I haven't been keeping track but will try to give my ColeParmer guy a call and see if he can provide me with a list of all part numbers that fit our criteria.

slief, tkeracer619 Thank you for your answers. Excuse me, I use it in a calcium reactor. Now at least I know it's not defective. And yes, by RPM it is the best option although there are others like using the OTHER SIZE settings, or actually using another size of tubing like # 16. But now and as long as the 5 feet I buy from tubing # 17 lasts I'll use the RPM mode. Again, thank you very much for your answers and help.

The head part numbers are important though, ideally you want ones that are compatible with LS17 tubing. Edit: The one in the for sale forum? Yes, the drive and pump heads will work

Since there is going to be some down time on my pump. I was thinking of picking up the Kamoer FX-STP. Would any body know the conversion from LS 17 which I think is 1/4 to 1/8th which is on the FX? I really don't want to pickup something that I would max or can't handle it. I was running it at about 54 mil p/m.

I picked up a master flex 7550-60 so I can tune my reactor better. The 7550 is replacing a 7520-00. The old ones start up when power is applied. Then 7550 requires me to press the start button. I remember reading about an auto start feature for the pump. I just can't find it now. Does anyone know how to turn on the auto start feature so it picks up where it left off and continues to run after the power is cut to it?

Also why is it preferred to get a 10-600rpm vs the 0-100 rpm. 100 rpm with ls17 is 283ml/hr. Most of use aren't approaching half of that.

Also even the brushless 100 rpm models can be fairly noisy at realistic operating speeds vs the 600 rpm ones. But yeah, bigger motor ran slower will be more silent and last longer than a smaller motor run faster Sent from my iPhone using Tapatalk Pro |

That makes sense. One of these days I'm going to get a pair of the right masterflex pumps......
Right now I have 2x 7520-00 a 7550-30 and a 7523-30. Sent from my Pixel 3 XL using Tapatalk |

Leaks
Every few weeks now my tubing springs a leak. This didn't used to happen.
Anyone know the cause or the fix? It's LS17 tubing. I am . out of town (of course) and don't have the pump model but it's not the brushless.
