 The MKII Pump from Keg Land is a magnetic drive high temperature pump capable of pumping  hot wort at temperatures of up to 248° F.  It can pump up to 5 gallons per minute, making it perfect for 5 to 20 gallon systems.  The maximum height it can pump is 11’ although gallons per minute will be reduced at higher pumping elevations.

  The pump head and impeller are constructed of food grade Xarec plastic (very similar to Polysulphone). The magnetic drive acts as a clutch allowing the user to put back pressure on the pump to slow down flow.  Like all magnetic drive wort pumps, it is not self priming - you must flood the pump head before turning on the pump.  The pump has ½” BSP male fittings on the inlet and outlet, which are compatible with all our ½” female NPT fittings. The inlet is in the center. Besides Xarec plastic, other wetted interior materials are nitrile rubber and stainless steel.

 The magnetic drive ensures no lubricated bearings are in contact with the liquid at all, so you can be sure there is no chance of any contamination of the liquid being pumped. The pump features a 67” power cord, and a mounting plate for permanent mounting.  The pump is 7¾” in overall length, and 3¼” wide including the mounting plate. The polysulfone head can be mounted at any angle on the pump to fit your application (an optional stainless head, William’s item Q80, is also available).   Shop around and compare, we think this is the best value currently available in a high temperature wort transfer pump.

 Important Safety Notice: This pump, like all 110 volt items that run in potentially wet areas, should be plugged into a GFI protected outlet for safety.

Solid pump, brittle plastic.

Review by Carl on 12/14/2015

Great little pump overall, small, quiet, good flow rate, primes about as easy as a chugger. However if you purchase this factor in the cost of the stainless steel pump ($30) head and replace it before even using it. I was putting together a half barrel system and without even getting to use one of the pumps I busted the threads off one head by hand tightening a fitting onto it. Totally worth it if you plan to grab the SS head.

So far so good

I have done two five gallon batches with this pump. primes easy with gravity. I pump through the whirlpool for a couple of minutes during the boil to get it all sanitized and then at flame out I run the whirlpool for a few minutes and chill it down to about 175f. add late hops and let it sit for 20 minutes. Then I run the whirlpool and the immersion chiller until it's down to pitching temps. The pump has worked great! Next batch is a lager and I plan to run the wort through my counterflow chiller to get it down below 60f.

A great little pump.

I've only used it so far for wort recirculation when using my immersion chiller, but it works like a charm. I added the SS head, and have only used it with it. In a test, it emptied half of my 8 gallon kettle is about 35 seconds.

Great pump

Review by Matthew on 2/9/2016

This is a great little pump especially considering the price. It is quiet and powerful. I really like it. I am sure I will buy more. I did add the stainless steel head to the pump. I like it better than my other March pumps Very happy with this purchase and would recommend this to friends.

Great Bargain but get the stainless head

Review by Steve on 2/18/2016

Low cost, quiet, and works well but don't even think of using NPT fittings with Teflon tape on the plastic head. The pressure side port broke off mine on the first turn. Bought the stainless head and all is good. Maybe hand tightened O-ring seal connectors (garden hose style with matching threads) like the Blichmann's would be safe on the plastic head but those are $12 each so just get the stainless head and breath easy.

Q: Can this pump be lubricated? Mine is seized and only barely turns by hand.

A: Try removing the head and checking for obstructions. If the impeller is damaged it can restrict movement. A new impeller is part # X11 if this is not under our one year warranty.

Q: Do you have a recommended cleaning procedure for this pump? I.e. do you run a cleaner through and then a sanitizer? Do you recommend a specific cleaner or sanitizer?

A: Always rinse out your pump so soon as you are done running wort through it so the wort won't have time to dry inside making cleaning more difficult. Follow that with cleanser, clear water then sanitize. As far as cleansers go the best way to clean the pump is with TM Desanamax (A36) as this cleanser will tell you when your pump is clean inside. When you mix it with clean water it turns purple. Then green or yellow if it detects any organic matter. When it runs purple again, your pump is clean. Flush the pump with clean water until it runs clear then sanitize with Star San HB (A43 or A44) or Saniclean (A48) and allow it to dry.

Q: Can you add a product thumbnail of the specification sticker similar to the 6W pump variant?

A: Good idea, we have just posted this picture.

Q: I want to use this pump to supply cooling water for a small marine air conditioner. Can this pump be run continuously?

A: This pump does have a continuous duty cycle so it can run for extended periods of time, however it wasn't designed to be run 24/7 so we cannot guarantee it will run forever without rest periods or overheating.

Q: I'm looking for a replacement impeller for my pump, the magnets in mine has swelled and prevented it from pumping, would this be something I could purchase from Williams brewing? Thanks!

A: Yes, we have this, search for Impeller part X11
