When siphoning is impractical or too time consuming, the home winemaker needs a pump. We helped pioneer the use of diaphragm pumps as an economical, gentle method to move small volumes of wine.

This new take on an old favorite includes speed control. Now you can dial in the flow from 0 to 3 gallons per minute. Gentle, economical, flexible, and wow are all adjectives we would use to describe the performance.

When this pump was first introduced to us, we loved the idea, but had concerns that the speed control would compromise the longevity of the motor. We build much larger pumps (our ChunkyPumps for commercial wineries) and normally you need a $700 frequency drive to control motor speed. However, we kept in touch with the manufacturer and after three years in which he has not had any issues, and after our own testing, we are now sold that this pump performs as promised. The manufacturer offer a 1 year warranty.

A diaphragm pump works by moving wine through one pulsating diaphragm into the next. In this design, as opposed to a centrifugal pump which has a small head spinning at high speeds, the shear value is small meaning the wine is not as "beat up". A diaphragm pump is self-priming, meaning that it will "pump air" creating suction that will pull liquid out of your container and into the pump head. This makes the pump very easy to use for the home winemaker.

  • This pump comes with 1/2" barbed ports for easy connectivity. 
  • Comes with 6' tubing on both sides.
  • 110 Volts, 0.5 Amp, 60 Hz.

Includes a built-in pre filter to help prevent solid materials from entering the pump head and potentially damaging the diaphragms, which would prevent the pump from being able to move liquid. The clear plastic top of the pre filter unscrews for cleaning.

It says in the product description that the pump can handle liquid temps up to 212F with silcone tubing, but the instruction manual says that liquid temps shouldn't exceed 130F. Can this pump handle temps up to 212 with proper hosing?
Bill Rittenour on Feb 16, 2018
BEST ANSWER: Yes, as long as you replace the tubing that comes with the pump with tubing that can handle over 212 degrees.
What is the lift power of this pump (How many feet?). I plan to place the pump on the floor and the input will suck the wine from the barrel on the floor and the output will go to my stainless still tank at 6 to 7 feet high.
Milton Tolikas on Oct 4, 2019
BEST ANSWER: Hi Milton - under ideal conditions, the max lift is approximately 15 ft. However, many factors come into play -- such as the type of liquid being moved, the temperature of the liquid, and the amount of solids in the liquid -- which determine the max lift of the pump on a case by case basis. This is why we do not list a max lift in the description. You should have no trouble in the set up you describe, although we would recommend doing a test run with water to see how the pump performs with your system.
How often should I change the filer if I am using it to move finished beer from two 6 gallon carboys to Corny kegs about once every other month?
martin smith on Apr 3, 2021
BEST ANSWER: The "filter" is a ring of SS mesh. Good for keeping grape seeds and skins out of the pump. The head disassembles and it can be washed clean. You should not have to replace the "pre-filter"unless there is physical damage.
There is a clip on the body of the pump, that secures the In and Out fittings. Slide it towards the back of the pump to release the fittings. The wire ring in the "filter" can be tricky to re-assemble, but patience is all it takes.
Would this pump be appropriate for pushing RO waste water through my plate chiller to cool wort? My plan would be to have the pump resting on top of a 50 gallon water storage tank about 30” above the tanks drain valve (supply water) and about 4’ away from the chiller. Essentially, the water would need to flow up 30”, horizontally 4’, then down and up another 30”. Want to make sure the pump is powerful enough for the task. I like the fact that it’s self priming (the pump would be sitting above the water level in the tank) and that it has the ability to regulate the flow as I never run my chiller water at full blast. Also, is there an on/off switch? Thanks.
Ken Yorke on Mar 17, 2021
BEST ANSWER: It will work over this distance, but the key is how fast you need the water to flow and if the waste water is free of any silt. I never runit faster then 2 gallons a minute and any silt can damage the diaphram.
Will pumping an alkeline water solution from barrel damage the pump?
John DiMeo on Sep 4, 2021
BEST ANSWER: I don’t know. Mine was adding air in the lines so I don’t use. Now I rely only on gravity
Can you use this to push wine through a Ferrari gravity feed filter?
RANDALL P OKON on Nov 10, 2020
BEST ANSWER: I'm not sure - the pump is not aggressive and it provides a slow steady flow for finished wine without aerating it.
I used my pump for the first time to move ten gallons of beer to the kegs and it foamed up bad I’m afraid that this batch will be oxidized. Is there a fix for the foaming problem?
Russell Chance on Jul 6, 2018
BEST ANSWER: Are you sure that was air making the foam. In a closed loop system where does the air come from? It is much more likely that the foam was CO2 being pulled out of solution due to the pump suction.
What is the head lift on this pump?

Wish we had bought a long time ago!!
Our wine club was a bit reluctant to try a pump- but we did!
This pump worked really well and saved us so much time and labor lifting the heavy car boys! Cleaned up easily and ready to go for the next racking! We love it !

Very useful pump for transferring wine
I make about 30 gal of wine and used the diaphragm pump to move it from primary to secondary fermenter. I usually use a larger diaphragm pump that operates using compressed air and has a much higher flow capacity. But this year I decided to try the SuperTransfer pump because it seemed this technology had advanced to the point where such a pump might simplify the job. I was pleased to find that was the case. I think the reported maximum flow rate is accurate and overall the transfer task was simplified. The filter did clog toward the end of transfer but it was easy to clean it and finish the job.
