SF210TAB RED FERMENTED WHOLE CLUSTER CAPACITY/H at 2,5 BAR RED FERMENTED WHOLE CLUSTER CAPACITY/H at 2,5 BAR for over 60 years, and from the early years we have especially focused on the research and development of the peristaltic pump. Today we are in a position of proposing solutions for every industrial field with the reliability and quality that we have built RED FERMENTED WHOLE CLUSTER RED FERMENTED WHOLE CLUSTER our success upon. CAPACITY/H at 2,5 BAR We have been manufacturing pumps

Simple Principle The basic principle of the peristaltic pump traces back to human “peristalsis” a term referring to the alternating contraction and relaxation of muscles around a tube to force the contents through it. An elastomeric tube is squeezed along a length by rollers that push the fluid contained within. The tube’s restitution after squeezing produces a vacuum that draws fluid continuously into the tube. This creates a gentle pumping action that doesn’t cause any damage to the product. Contaminations are avoided because the fluid is contained within the tube (one contact part with...

Rotho’s advantages ~ The most gentle pumping action available ~ No contact with moving mechanical parts during pumping ~ Totally sealed pumping system ~ Can be operated dry without damage ~ Self-priming wet or dry with negative heads up to 8,5 m ~ Can be reversed and run in either direction ~ Only the smooth and soft internal tube layer contacts fluid ~ No crushing of stems, berries or seeds ~ No seals or check valves to cause obstructions or wear This pubblication supersedes and replaces any previous edition and revision. We reserve the right to implement modifications without notice. This...

For WHITE wine processes - The Rotho peristaltic pump does not damage the grapes, skins, or seeds, during pumping. - The stems are not crushed or broken stems or whole clusters pass easily through the ROTHO pumps. - Can be operated dry without any damage. - Comparative tests have shown that more than 50% of the whole berries being pumped pass through the ROTHO pumps totally intact and without damage - Tests have shown that when pumping white whole berries, crushed berries or whole clusters with the Rotho system there is a 10-15% lower polyphenol content than with traditional systems.

For RED wine processes - Ideal for pumping over during fermentation with a total control of exposure to oxygen. Oxygen can either be minimized or added if desired. - The gentle pumping action does not damage solids during pumpovers, which results in superior colour and aromatics qualities. - Comparisons have shown that when a ROTHO pump is used for the entire RED winemaking cycle there is a considerable reduction (from 20 to 50%) in the quantity of LEES produced compared to other processes.

For RED fermented - The “Delicate” ROTHO treatment of the product without crushing or tearing of the stems and skins results in a decrease in the percentage of LEES of 33% when compared to other systems. - The gentle ROTHO system does not cause any change in the liquids or solids being pumped-no aeration or contamination. For Feeding Chillers - Gentle ROTHO pumping action does not cause emulsification, which can change solubility characteristics. - In addition, when equipped with a variable speed control, the ROTHO pump is able to optimize the thermal exchange and solubility...

For Barrel Work and Bottling - Gentle ROTHO pumping action is ideal for feeding a bottling line or filling barrels. - The complete line of Rotho pumps also includes small pumps for filling and emptying barrels without any foaming, mixing or contamination. General Pumping Operations In addition to being the gentlest pumps available, with pumps from Hl/h 2 up to 700, the Rotho pumps offer the highest quality solution for all winery operations THROUGHOUT THE YEAR.

Dosing of Enzymes and Chemicals Products The Rotho pump is able to dose enzymes, bentonite, glycerine, etc. with an accuracy of from 0.5 to 1.0% for very effective wine or must treatment with less maintenance cost due to the Rotho pump’s excellent resistance to abrasion. Dosing of Water Based Sulphurous Anhydride The Rotho pump can very effectively dose water based sulphurous anhydride with an accuracy of from 0.5 to 1.0% because of its chemical resistance and the positive shutoff of the roller-tube interface. This can be accomplished without any valves and without any off gassing, even...
