Wine Pump-over

FOR MACRO AERATION:

Winemakers everywhere are discovering that pumping juice through a Mazzei wine pump-over venturi injector during fermentation aspirates a substantial amount of oxygen into the liquid. Mazzei injectors are highly efficient, low-cost devices for energizing fermentation.

During the macro aeration process, wine is pumped through a Mazzei injector that draws in and uniformly distributes air into the juice, oxygenating the wine. Trouble-free with no moving parts, Mazzei wine pump-over injectors are simple to use, easy to clean and self-priming, and they can run dry without problems. Mazzei injectors deliver superior mixing and contacting because of their patented technology, meticulous engineering and high-quality manufacturing.

BENEFITS OF MAZZEI WINE PUMP-OVER AERATION:

• Enhances Color and Character of the Wine
• Supports Yeast Development and Viability
• Reduces Sulfide Production
• Excess Carbon Dioxide is Purged from the Top of the Tank
• Can be Used During Racking or Mixing
• Installed at Top of Fermentation Tank or at Pump Discharge
• Installed and Maintained Easily
• Can Introduce Fining Agents and Other Wine Additives at the Suction Port of the Injector
• Can Control the Rate at which Liquids are Drawn with the Addition of a Metering valve

FOR MIXING LIQUID ADDITIONS DURING RECIRCULATION:

The pump-over injector can also be used for liquid additions to tanks during recirculation. Simply connect an injector to the discharge side of a pump that is being used to recirculate the tank. Connect a suction hose from the injector’s suction port into the container of the desired addition (either fining agent, carbon, tannin, or anything liquid), and when the pump is running, the pump-over injector will draw the liquid into the tank at a rate you determine by the use of a throttling valve. There’s no need for a stand-alone dosing machine, and you won’t have to haul buckets to the top of the tank—additions can be made safely from the cellar floor.

AVAILABLE MATERIALS FOR WINE PUMP-OVERS:

• Machined Stainless Steel
  Mazzei uses 316L stainless steel for its 316LSS wine pump-over injector models. 316L stainless is highly corrosion resistant and has a low carbon content, which eliminates carbon precipitation in the welding process.
• Cast Stainless Steel
  Venturi injectors made of CF3M cast stainless steel are complementary products to our injectors made of 316LSS, a machined product. The cast stainless steel product is a low-cost equivalent that still offers vintners all of the high performance and quality they expect in a Mazzei product. With tri-clamp fittings at all openings, the cast 2081 and 3090 injectors can be installed and maintained easily. The cast stainless steel material resists corrosion and is easy to clean.
• Natural PVDF
  Mazzei also manufactures a complete line of natural PVDF venturi injectors for the wine pump-over market in various sizes and corresponding suction capabilities.
