Description

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. Please note that some customers have had trouble unscrewing this cover to clean their filters. We suggest using a standard strap wrench if you are having difficulty with yours.

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.

seems to work fine
Have used it once to rack 6 gallons of wine from a secondary fermenter into another one. The variable speed was really helpful in preventing the transfer of sludge from the bottom, allowing a more delicate control. Haven't used it yet to transfer from a primary fermenter where oak chips and lots of sludge might be a challenge. The best part is not having to lift about 50 pounds of liquid straight up onto a counter top.

An OK pump.
This little pump is useful for topping wine barrels or for transfers of small amounts of wine. The tubing included with the pump seems to be of non-standard size, and the speed control goes from zero to nearly full speed fairly quickly, so a light touch is needed on the speed control. Otherwise a good pump.

works
Used the pump several times now and gave it five stars because it's performing as advertised. A bit of food grade silicon grease on the filter threads helps. Be careful re-fitting the filter screen as it can be crimped. Does have to be anchored to a board, the hoses are stiff. Very handy.

Makes Shirt Work of Wine Transfers
I am very happy with this pump. It is easy to sanitize and clean, and it makes racking quick and simple. I’m not sure what I would do without it.

Pretty good
So far so good on the second pump delivered. First one was broken where the filter attaches to the pump. It runs great but feels fragile

Puts air into the lines
The pump itself works fine but because of the pre filter it will suck in air where it attaches to the housing thus putting air into the suction line. Not good for wine making

One great pump!
I was on the look out for a great transfer pump, after studying wine making at Surry Community College. This pump works just as well as the commercial pumps we used in the College's winery, but on a much smaller scale which is spot on for a home wine maker.
