Mark II Pump with Steel Head
Let’s face it, pumps aren’t the most exciting piece of homebrew equipment you own. With the exception of the RipTide pump, they don’t have “features” you can impress your friends with. There are a few basic requirements, and once you get those met, you’re just looking for the lowest price. For me, the basic requirements are: 1) Magnetic drive, 2) Ideally a stainless steel head, 3) Temperature & splash protection, and lastly 4) Maximum head.
The MkII’s Magnetic Impeller
Several vendors offer what’s called a “Mark II Pump”. So you need to dig deeper than just the name when comparing pump offerings from different shops. One requirement, which is pretty much standard across beer brewing pumps, is what’s called a magnetic drive. Magnetic drive means you don’t have to worry about grease from shaft bearings getting into your wort. The other advantage is that you can close a valve- partially or completely- on the output side of your pump to reduce flow, and it causes no stress to your pump. Magnetic drive is pretty much standard in beer brewing pumps, but I bring it up because shopping on Amazon or eBay you might get drawn into something that isn’t.

About Pump Features and Specs – What does Pump Head Mean?
Pump heads come in either stainless steel or some kind of plastic/resin. Some resins have a better temperature durability, so after many hours of operation they are less likely to break down and lose pressure/flow capability. Stainless steel doesn’t have this issue, but it also has more durable threads. Most wort pumps come with 1/2″ Male NPT at inlet and outlet so you can screw on hose attachments or ball valves. I’ve had bad luck with stripping threads off a polysulphone pump head even with the most careful attention paid to not cross-threading it.
The next key differentiator between pumps is temperature capability. Some are designed to handle cooler liquids and are maybe only rated to something like 80F or 180F. This simply isn’t good enough for brewing, you want something that can handle boiling wort temperatures (212F or hotter).
