Description

The BLA double stage liquid ring vacuum pump series derive from the BLN for sizes 200, 230 and 250.

Of a more compact and economic construction, the BLA pumps, due to their reduced number of internal components and simplified assembly, result in lower purchasing and especially maintenance costs, all of which without jeopardizing their performance. The reduced number of components for maintenance in stock, fewer parts to be aligned and sealed, reduced shaft length resulting in less deflection plus the standard use of mechanical seals, indicate that the BLA pumps are a great option where medium sized vacuum pumps are concerned.

Applications

  • Upon aspiration of dry or saturated gases, they allow for the intake of liquids that may eventually be drawn, reaching a vacuum of 30mbar or even more when fed with low vapor pressure fluids or assembled with ejectors or BOOSTERS*. Some of the typical applications include:
  • Distillation process of the chemical and pharmaceutical industries, and vacuum distillation process in petroleum refineries;
  • Evaporation process of food industries, sugar or alcohol mills;Bottle filling machines;
  • Junto a máquinas enchedeiras de garrafas;
  • Degaseification of plastics and resins;
  • Sterilization process (autoclaves);
  • Drying;
  • Priming for centrifugal pumps and systems;
  • Evisceration; and
  • Hospital applications and others.

Materials

  • Cast iron, 304 or 316 stainless steel; other alloys under request.
  • Do not require any kind of lubrication at the operation/work sites.
