200 - 2 880 m³/h | RV series PEDRO GIL

ROOTS PUMPS RVB TYPE
The RVB pumps are used in combination with a previous series of pumps and can also be used with condensers arranged in series connection.
CONSTRUCTION CHARACTERISTICS The Roots-type pump drive shaft is directly driven by the motor shaft by means of an elastic coupling. The shaft passage is closed off by seals with an oil chamber, the oil being used as a sealing fluid. A cooling chamber is included for the shaft passage to eliminate the heat produced by the seal. The seals and the rest of the elastomers are made of VITON Fluorinated elastomer. The RVB type is supplied with an AC, three-phase motor and standardized flanges, in accordance with IEC standards.
ROOTS PUMPS RV TYPE The application is identical to the RVB type. CONSTRUCTION CHARACTERISTICS These are the same as for the RVB type, with the variation that they are supplied without the motor anchorage support, elastic coupling or motor. In short, the model is supplied with a free shaft.
