Variable Speed Diaphragm Pump (0-3 GPM)
H308
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.
