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.
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:
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:
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 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.
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.

FIELDS OF APPLICATION
The RVS pumps are suitable to compress gas and vapours in the process of
sterilisation, concentration, drying, impregnation, plastic extrusion, degassing and
extraction of non-condensable gas from condensers in the chemical, pharmaceutical,
food, pulp and paper, sugar, textile, in power plant industry and in hospitals.

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.).
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.
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.
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.
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.
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.
