The MkII pump is actually just a "ripoff" as well, if you want to look at it this way. KegLand (AU) did not design or manufacture that pump.
The MkII, the pump in the Grainfather, and many similar looking pumps are all part of the Chinese-made MP-series magnetic drive pump, or knockoffs. There are many manufacturers in China making these. An American company can travel to China or work through an agent in the U.S., EU, AUS/NZ, etc. to contract for a private label pump based on one of this family of pumps. As a part of it, you can choose which pump from this series you want to use as the base model, customize it, get your own decal put on, and then use another agent to have them shipped to your warehouse.
In the case of OP /u/sktyrhrtout, it looks like they made the SS pump head standard equipment rather than an upgrade, and to have a different cord put on (a switched cord). This one's specs seem to indicate it uses less power to get the same flow rate and head, so it's possible the impeller design is a little different. But it's the same or close to the MP-15R pump. Compare this similar product, where the label clearly identifies it as a MP-15RM-110 model pump.
Considering that Amazon protects you from fraud (I think), it seems like a good deal for someone looking for this type of pump. I have a Riptide and a little solar pump, so I'm not in the market.
There are plenty of center-line pumps that have 1/2" NPT threads on both inlet and outlet, I would know - I'm using one.
If you're using a pump you're going to want to move to quick disconnects for your liquid lines anyway, but I agree it's easier to pick one that has 1/2" openings on both ends, particularly because the QDs come cheaper when buying in pairs.
I got one of these recently and it's worked out for me so far. I have yet to attempt an IPA with it since I got it though, so YMMV with a ton of hop particulate in the wort. I am attempting a SMaSH with 5oz of hops in the kettle this weekend though, so I can definitely report back.
That said, the pump was definitely adequate to push wort through the counterflow and back into my whirlpool arm, though it is the same 19L/min flow rate you say you're having trouble with. Upgrading to a Chugger or Riptide pump might be something worth thinking about?
How much money do you want to spend? What kind of cleaning system are you going to implement? I used to dairy farm and we used stainless steel impeller pumps. You can also get pretty big peristaltic pumps. There are cheaper options out of china for this sort of thing also but ti comes down to what kind of money you want to spend how you plan on cleaning it, and if you need it certified or just clean enough for your personal use. I googled "food grade pump" and this came up. If you want to look at something try checking dairy, brewery or commercial restaurant suppliers in your area.
This little peristaltic pump is claiming up to 5L/min
Has anyone used these pumps
I'm a really big fan of the farroday pump that I got last year on amazon. It has a stainless head, 1/2" NPT on both sides for thread, and chugs along strong. There are a number of $75 wort pumps that are probably all made in the same factory in china and likely work just as reliably. It's nice to put a ball valve on the output too so you can throttle it if you need/want to.
For the sprayer, try this one if just using a barb or Quick Disconnects, and this one if you have triclamp stuff.
Worth noting, if you're going the pump route you almost certainly want quick disconnects on everything (ball lock vs camlock is personal preference). Denord brand on amazon is pretty reasonable, pretty sure I ended up making 3 transfer hoses (female on both ends) of various lengths as well as male fittings on the ends of anything threaded I own. Those can add up quickly, I ended up spending over $200 to outfit everything when I bought my pump.
So many pumps..... Looking for a good option that won't break the bank, for recirculating and transfer. Has anyone used this pump? - https://www.amazon.com/dp/B073P19L8P/ref=cm_sw_r_cp_apa_i_5cYDFb848JA80 I think I'm in analysis paralysis

Just a random $70 Chinese pump from amazon. I figure if it breaks I’ll invest in something nicer - basically treating it like Harbor Freight tools.
