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 a couple years ago, 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 the pump performs as promised. The manufacturer does offer a 1 year warranty as well.

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.
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.
