LIQUID RING VACUUM PUMPS
RVS SERIES
Main technical features
- Absolute inlet pressures up to 33 mbar.
- Flow rate up to 4200 m3/h.
- Motor power from 1.5 to 55 KW.
- Maximum gas inlet temperature: 100°C.
- Maximum service liquid temperature: 70°C.
- Noise level at 80 mbar: 72-79 dB (A).
Performance and advantages
- Possibility of sucking gases and vapours, also in the presence
of entrained liquids.
- Isothermal compression of gases.
- No lubricant in contact with pumped gases.
- New hollow shaft coupling to make maintenance even easier
and quicker.
- No parts subject to wear.
- Significantly reduced vibrations.
- Reduced noise because of new patented integrated
silencing device.
Fields of application
Suction of gases and vapours in various industrial sectors:
- Chemical, pharmaceutical, food, paper, hospital, sugar, textiles
and energy.
- In the processes of concentration, drying, impregnation, plastic
extrusion, degassing, extraction of non-condensable gas from condensers,
autoclave sterilization.
Optional
- Anti-cavitation devices.
- Silenced probes for the discharge.
Special productions
Integrated packages with pumps in parallel, separating tanks, systems
for automatic reintegration and cooling of the service liquid, control
instruments.
PACKAGES
 LRVS
PUMP PACKAGES
Packages comprising pump, motor and separator.
The transmission uses belts and pulleys and is based on a patented
motor swinging suspension system.
Advantages:
- Because of the belts coupling it is possible to select the vacuum
pump that operates at the best speed, so as to minimise
both the overall dimensions and the operating costs.
- Reduced load on the pump and motor bearings.
- Possibility to maintain the tension of the belts
over time.
- Easy to replace motor with types of various
shape and with various characteristics
 CRVS
PUMP PACKAGES
The transmission is obtained through an elastic coupling.
The pump rotates at the synchronous speed of the three-phase motor.
Advantages:
- Easy to integrate in complex plants
KRVS PUMP UNITS
 These
units consist of RVS pumps with separator
tank for the recirculation of the service liquid and connecting
piping.
Two versions are available:
- KRSV/P with partial recirculation of the liquid .
- KRSV/T with total ricirculation of the liquid : this
version is equipped with heat exchanger.
Advantages:
- Extremely low levels of noise and vibrations.
- Separation of service liquid
from discharged gas.
- No contact between the cooling liquid and the
pump.
- Very easy installation, start-up, setting and
maintenance.
The availability of the vacuum packages allows the plant installer
to make use of a complete and independent
unit, and this enables him to concentrate on the specific requirements
of the plant.
