WINE PUMP-OVER FOR MACRO AERATION & FOR MIXING LIQUID ADDITIONS DURING RECIRCULATION

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 air/oxygen into the liquid. Mazzei injectors are highly efficient, low cost devices for energizing fermentation. During the macro aeration process, the wine is pumped through a Mazzei injector which draws in and uniformal distributes oxygen into the juice. Trouble-free with no moving parts, Mazzei wine pump-over injectors deliver uniform distribution. They are simple-to-use, easy to clean, self-priming, and can run dry without problems. The superior mixing and contacting achieved is due to Mazzei’s patented technology.

BENEFITS OF MAZZEI WINE PUMP-OVER AERATION PROCESS:

  • 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

  • Fining Agents and Other Wine Additives Can Be Introduced at the Suction Port of the Injector

  • Rate at Which Liquids Are Drawn Can Be Controlled with Addition of 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 which is being used to recirculate the tank. Connect a suction hose from the injector’s suction port into the container of mixed 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. No need for a stand alone dosing machine. No hauling buckets to the top of the tank—additions can be made safely from the cellar floor.

 

WINE PUMP-OVERS ARE AVAILABLE IN THE FOLLOWING MATERIALS:

Cast Stainless Steel: Made of CF3M cast stainless steel, our model 2081 venturi injector is a complementary product to model 316LSS, a machined product. The cast stainless steel product is a low cost equivalent which still offers vintners all of the high performance and quality they expect in a Mazzei product. With tri-clamp fittings at all openings, the 2081 can be installed and maintained easily. The cast stainless steel material resists corrosion and is easy to clean.

Natural PVDF or ECTFE: Mazzei also manufacturers a complete line of venturi injectors for the wine pump-over market that includes natural PVDF or ECTFE in various sizes and corresponding suction capabilities.

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.
