RBVM68 provides optimal conveying of material in a 4 Inch pipe upto 1200 mBarG, for a minimum material transfer of 8.3 tonnes/hour.
The conservative load carrying capacity of the larger diameter bearings ensures an extended operating life. Timing gear life is also extended by a controlled lubrication system.
The computer calculated impeller profiles ensure maximum volumetric efficiency with minimum absorbed power without sacrificing torsional rigidity. The high rigidity of the impeller and generous shaft diameter keeps stresses low.
Gear and shaft strength is substantially increased by the use of slow taper mounted gears which do not need keyways for location. This also simplifies the setting of the gear wheels to obtain correct timing of the impellers, a feature that facilitates field maintenance.
Precision ground and hardened steel gears are used to ensure smooth running and accurate timing of the rotating impellers. Specially designed rotary oil seals are used in the gearcase.
This feature eliminates maintenance associated with the use of lip seals. This range can now be supplied with oil lubricant at the drive end as well as the gear end and thus helps to simplify maintenance.
This feature is particularly attractive where the blower is used in high ambient temperature conditions.
Design and manufacture is in accordance with metric standards.
