Product Description
This lantern bracket liquid ring vacuum pump from Salvatore Robuschi is a single-stage pump with exhaust valves, connected to a standard IEC electric motor through a lantern bracket and elastic coupling. It reaches vacuum levels down to 33 mbar abs and handles dry air capacities from 40 to 378 m³/h at 50 Hz.
The lantern bracket design is built for versatility, allowing higher power motors to be installed for more demanding applications. Heavy-duty, lifetime-lubricated bearings are sized for maximum durability, and the pump-side bearing is protected from external contamination by a lip seal.
Maintenance is quick and simple. The distribution valve is accessible from the outside and can be replaced in minutes, solid gaskets replace planar sealants, and a patent-pending adjustment system uses a standard Allen key without removing the impeller. The design also gives special attention to optimizing service liquid consumption.
The pump is available in cast iron or AISI 316 stainless steel construction, with an AISI 316 distribution plate and PTFE valves on every version. ATEX versions are available for potentially explosive atmospheres.
Liquid ring vacuum pumps are commonly used for vacuum drying, degassing, filtration, distillation, and evaporation in the chemical, pharmaceutical, plastics, and paper industries.
