5 MagDrive 250

I have used these pumps in my DIY CO2 reactor (upflow design). The pump is mounted externally and works great - no leaks / quiet. The only problem I've seen is if fine particulate matter from the reactor is allowed to circulate for long periods of time or repeatedly. The abrassive nature of the particulates wears the inside lining of the pump leading to some slop in the spinning magnet and then vibration sound. In extreme cases, I've seen the casing worn completely through resulting in a short. If I keep the flow rate through the reactor under control, the pump lasts a long time and works fine.

These are great pumps. Indestructable in my opinion. I have 3 of them. One is used externally on my calcium reactor and has never leaked or failed. One of them had a problem starting after 3 years of CONSTANT use and MANY times running dry. Put a new impeller assy in it and it worked like new!

These pumps are quiet but I purchased 2 and they both leak. Poor design for external use.
