Vacuum pump RVV

Vacuum pump RVV is designed for under-pressure conditions and for exhaustion of gases generated during processes in pulp and paper industry. It is necessary to reach higher under-pressure values than that of standard fans. Vacuum pump can exhaust also gas-liquid mixtures where a liquid share is up to 1%.

Vacuum pump is allowed to be used only for gas mixtures with no chemical impact on pump parts, with no abrasive particles and if mutual mixing of the given medium with operating seal water is not a hindrance.

Design

Vacuum pump RVV is manufactured either without drive, i.e. as a reserve for replacement, or with a driving electric motor coupled directly through an elastic coupling on a common base frame, respectively with a V-belt drive. This V-belt drive is delivered separately according to the required interaxial spacing, however, without guard because necessary guard shall be finally specified when projecting according to the proposed way of driving.


Material

• casing, covers and bearing housings are casted
• impeller is made of bronze
• shaft is made of structural steel St 52

Machine design and work safety are in compliance with EU standards.

Main parts





• pump casing (1), covers (2), bearing housings (3), shaft with impeller (4), stuffing box (5)
• clutch (of pulley) (6) - according to actual modification
• frame under pumping set or under vacuum pump - according to actual vacuum pump modification (7)
• electric motor with sliders (8)
  
• set of V-belts (9)
• clutch guard of pumping set
• V-belt drive guard - to be specified in project according to required layout - per order

Advantages

• easy operation
• no extreme demands on maintenance
• simple regulation of vacuum and exhausted volumes
  

Accessories

• vacuum meter, pressure gauge, valve of service water
