Self-priming means the pump will pull a vacuum and draw liquid from a submerged inlet line into the pump head. The gentle action of the diaphragm mechanism minimizes oxidation and shear stress of your wine during transfers. Additionally, the speed adjustment knob allows you to vary the pump flow rate between 0.8 - 3.0 gallons per minute. There is no risk of any metallic interaction with acids in your wine as the pump head is made of nylon and the diaphragm from Santoprene™.
The Vintage Shop SUPER Transfer Pump has a maximum temperature rating of 130 °F (rating on the included tubing) and is NOT recommended for wort production in brewing applications.
In May 2022, our staff performed an experiment to learn just how gentle this pump is when transferring wine. We tested the SO2 and dissolved oxygen impact on a wine before and after transfer. Further, we compared the results of pumping against other transfer methods including siphoning, and splash racking. You may like to review our results here!
When using a wine pump to push wine through a cartridge filter or plate filter, the efficiency of the filtration process is dependent upon the flow rate through the filter media. Ideal flow rates are as follows:
Coarse Filtration - 0.4-0.5 gallons per minute per square ft of filter pad surface
Polish Filtration - 0.13-0.4 gallons per minute per square ft of filter pad surface
Sterile Filtration - 0.05-0.2 gallons per minute per square ft of filter pad surface
