Liquid ring vacuum pumps

ROBUSCHI RVS With over 70 years of history Robuschi are capable of combining, in the best possible manner, their experience with the most advanced of technological innovations. At the beginning in 1941, their main activity was the repair of centrifugal pumps that were mainly used in agriculture. Their production, design and financial growth commenced between the 60s and the 80s. They asserted themselves on a national and international level through the production of 3 lines: centrifugal pumps for the chemical industry and channel pumps for waste water; liquid ring vacuum pumps; low pressure...

c The RVS series includes liquid ring pumps with innovative characteristics, which is able to suck in gas and vapours, without contamination from lubricants; also in the presence of dragged fluid and with nearly isothermal gas compression. Thanks to its construction features, the liquid ring vacuum pumps are V remarkable for low water consumption, low noise and vibrations, reliable service and minimum maintenance. The variety of construction materials allows a wide field of applications. In addition to this, they can also be used as a compressor within the limits shown in the use and...

RVS Liquid ring vacuum pumps Casing Reduced consumptions, thanks to the efficient layout of the internal intake and delivery gas baffles. Shaft The heavy-duty shaft is protected from the contact with the service fluid and conveyed gas, except for the RVS sizes 23 and 25, because the are made of stainless material (see the page Material execution) Shaft seal The RVS 3-25 includes single mechanical seals flushed from the service fluid. The sizes RVS 30-60 can be installed both packing seals flushed from the service fluid or from the outside, both double mechanical seals. Impeller The impeller is...

Electropump Units "\ CRVS The vacuum compact systems CRVS are equipped with a pump that is already coupled with the electric motor with elastic direct coupling. This ensures a perfect alignment, optimal and long-lasting operation. The CRVS base was specifically designed to guarantee high stiffness and low vibrations. LRVS The vacuum compact systems LRVS feature belt and pulley drive, a motor oscillating suspension patented system, which makes it possible to reduce the load on the motor bearings and pump, by keeping constant over time the belts tension. This makes it possible to easily adapt...

KRVS Vacuum units The KRVS are units developed for the vacuum generation in the most varied sectors, such as the chemical, petrol-chemical, pharmaceutical, textiles sectors…..and many more…. They consist of liquid ring vacuum pumps of the RVS series with separation tank for the partial recirculation of the service fluid and corresponding connection pipes (/P); in the version with total recirculation (/T) the unit is fitted with a heat exchanger. The separator tank also silences the noise at the pump discharge. The partial recirculation units (/P) are the Robuschi answer for the recovering of...

Anti-cavitation valves VGI: a new anti-cavitation device, which operates by means of a direct non-condensable gas injection into the compression chamber. The VGI device consists of a calibrated orifice, which is specific for each pump size, and of a non return valve, which was specifically designed to prevent the outflow of service fluid when the pump stops. This reduces thus the injection load losses. The non-condensable gas is also supplied to the pump straight after the closing of the suction phase, avoiding, therefore, the pump’s volumetric efficiency penalizing. The device is made of...
