RBS

RBS is the innovative positive displacement rotary blower with 3 special profile lobes that, combined with a new configuration of the LOW-PULSE system, reduces the residual pressure pulsation of the conveyed gas below 2% of the operating pressure.



RB-DV

The RB-DV series consists of 3 lobe rotary blowers used as exhausters which makes it possible to reach a high compression ratio by means of a patented atmospheric air injection device ROBUSCHI that reduces overheating of the gas and the power absorbed by the blower.

The main characteristics of these blowers are as follows:

  • Maximum vacuum 93% - 28"Hg on a dead head;
  • Nominal capacity from 840 to 10,500 m3/h - from 494 CFM to 6200 CFM;
  • Suction pressure up to 100 mbar absolute / -900 mbar;
  • Gases and vapours can be handled;
  • No sliding parts, therefore no wear;
  • Safe operation and minimum maintenance;
  • No oil mist;
  • Available on request, RB-DV in the ATEX version.



RBS/AV

The RBS/AV Blowers are rotary lobe blowers used to increase the capacity of the primary vacuum pumps when operating at their minimum suction pressure (as a booster).

The main characteristics of these blowers are as follows:

  • Suction pressure from 0.001 to 20 mbar absolute;
  • Suction capacity from 300 to 9,400 m3/h;
  • Gases and vapours can be handled;
  • No sliding parts, therefore no wear;
  • Safe operation and minimum maintenance;
  • RBS/AV in the ATEX version available on request.



RSW

The RSW compressor is the combination of a careful and precise analysis of market changes, such as processing and waste water treatment industry, as well as of the clients' constantly evolving needs, and of Robuschi experience in low pressure combined with constant R&D activity.

For these reasons, RSW is designed and developed by Robuschi: from the definition of the rotors' profile to the complete development of the compressor, which was expressly optimised to reach pressures of 2.5 bar (g).



ROBOX Evolution

ROBOX Evolution is an integrated compression unit designed to convey gas at low pressure, based on the RBS lobe positive displacement rotary lobe blower, operated by an electric motor through a special belt drive, including all accessories and noise enclosure.

The complete range of Robuschi blower units includes RBS blower sizes from 15 to 165, all with the innovative characteristics of the ROBOX Evolution compression unit.

These characteristics reduce: system costs thanks to the optimisation of space; running costs thanks to the low energy consumption and to the exclusion of all standstill risks ensured by the innovative electronic control system SENTINEL; maintenance costs thanks to the easy access to all parts for normal service operations.



CRBS - GRBS

These are compression units for low pressure gas conveying, based on the RBS series 3 lobe positive displacement rotary blower, run by an electric motor through a special belt drive (GRBS) or directly coupled by means of coupling joint with or without reduction gear (CRBS). They are provided with all the necessary accessories for reliable, safe and silent operation.

The CRBS and GRBS units can be used for capacities higher than 900 m3/h and for fitted powers over 250kW. The heart of the unit is the innovative RBS series blower. CRBS - GRBS in the ATEX version available on request.

KRVS 25/CT/T

SERVICE FLUID FLOW
With once-through or partial recirculation circuit, the service liquid flow is related to suction pressure and rotation speed.

With total recirculation circuit, the cooling water flow varies according to unit operating conditions (cooling water temperature, suction pressure, gas characteristics, etc.).



RBS/AV Blower with VP

The RBS/AV Blowers must be used in series with a primary vacuum system (VP) and for pressures lower than 50 mbar absolute.

Rosbuchi can supply primary vacuum systems consisting of liquid vacuum pumps with deliveries up to 4,200 m3/h.



RN / RNS Chemical Process Pumps

The PROCHEM pumps are single-stage horizontal centrifugal pumps with axial inlet, designed according to ISO 2858 and DIN 24256 standards. The PROCHEM pumps, thanks to the two differently shaped impellers are designed to pump clear or slightly cloudy liquid (RNS series) or solutions with suspended crystals, muddy and/or viscous liquids with suspended particle or fibrous materials (RKNS series), either chemically inert or aggressive, for use in the chemical and petrochemical industries, in mines and steelworks, in shipyards, in the pulp and paper industry, in the pharmaceutical industry, in textile and food processing industries, in power stations and in desalination plants.



RKC Toque Flow Pumps

In this type of pumps the pumping effect is obtained by exploiting the action of the vortex induced into the liquid by a special impeller. Thanks to the shape of the impeller and to its recessed position in the casing, the pumped liquid does not have to flow through any vane passages. It is therefore possible to pump viscous and/or pasty liquids containing foreign bodies of remarkable size and stringy matters without danger of clogging the pump. Moreover the action of the induced vortex enables the conveyance of media containing high percentage of air and/or entrained gas without showing those problems of the conventional centrifugal pump. The type of construction derives from the RN pumps line with consequent advantages of an easy maintenance and easy impeller replacement to possibly suit the pump to the varied conditions of services.



RKCS Process Pumps For Slurry

The RKCS Process Pumps For Slurry are single stage horizontal centrifugal pumps with axial inlet, designed to pump all types of chemical inert or aggressive liquids, also viscous liquids, and those containing high percentage of solid particles in suspension, and slurry.




RCN-RCPN / RCNS-RCPNS Channel Impeller Pumps

The peculiarity of these pumps is the impeller. It is of the channel type; ie. with wide passages between the vanes to enable the handling of media containing suspended foreign bodies without any danger of clogging.

The type of construction derives from the RN pumps line with consequent advantages of an easy maintenance and easy impeller replacement to possibly suit the pump to the varied conditions of service.
