The
installation of a single-stage centrifugal pump VNC-10/55, has a purpose: to
transfer of wine material, alcohol, liquids from communications, which have a
high hydraulic resistance, for the supply of wine materials to the filter
press.
The pump packs a wine material with a very high pressure effect: 0.5 (5) MPa (kgf / cm), pressure - 55 meters. This significantly saves the filter carton used in the filter-press.
In the pump
installation, the sealing elements located inside the pump, which are cooled by
the pumped liquid. End seal element, incl. spring - stainless food steel (12H18N10T).
The pump is made of bronze, in a mobile, explosion-proof design. Manufacturing with reverse feed is possible.
