Liquid ring vacuum pumps RVS series

 

 

 

 

 

 

The Robuschi brand stands out as one of the leading manufacturers of advanced vacuum technologies. Thanks to the RVS vacuum liquid ring pump design, suction of hot gases and water vapor is achieved in absolute vacuum range up to 33 mbar(a), without contamination by lubricants and with almost isothermal compression. Liquid ring vacuum pumps ensure the minimum water consumption, low noise and vibration with very low maintenance requirements. Various arrangements are offered (RVS, KRVS, CRVS, LRVS), especially designed for vacuum production in a variety of production processes and applications.

 

 

 

 

 

 

 

 

 

RVS/M series

The Robuschi RVS/M series consists of single-stage vacuum liquid ring pumps that are directly driven by a flanged motor with a common pump-motor shaft. Available in standard cast iron or stainless steel alloy.

• Connections 1" to 2 1/2"
• Electric motors 1.5kW to 5.5kW
• Absolute suction pressure up to 33mbar(a)
• Flowrate up to 220m³/h

RVS/SG series

The Robuschi RVS / SG series consists of single-stage vacuum liquid ring pumps that have their own shaft and bearings and are driven by a flanged, easily removable standard electric motor via an elastic coupling. Available in standard cast iron or stainless steel alloy.

 

• Connections 1" to 2 1/2"
• Electric motors 3kW to 11kW
• Absolute suction pressure up to 33mbar(a)
• Flowrate up to 400m³/h

RVS/TM-CT series

The Robuschi RVS / TM-CT series consists of single-stage vacuum liquid ring pumps with a suction and discharge collector which smoothens out the flow and noise. They are driven by an electric motor via an elastic coupling (CRVS construction) or trapezoidal transmission belts (LRVS construction).

• Connections 4" to 8"
• Electric motors 15kW to 90kW
• Absolute suction pressure up to 33mbar(a)
• Flowrate up to 4200m³/h

 

CRVS construction

In the CRVS construction the vacuum pump is directly driven by the motor via elastic coiupling. This ensures perfect alignment, optimum and long lasting operation. The baseframe of the CRVS is especially designed to guarantee high stiffness and low vibration.

 

 

LRVS construction

In the LRVS construction the vacuum pump is driven by pulleys and a special belt assembly which reduces the loads of the bearings while maintaining tension over time. The unit adapts easily to various motor sizes without altering its exterior dimensions. With the appropriate belt transmission selection optimum pump speed can be selectedavoiding excessive energy consumption.

 

KRVS series

The Robuschi KRVS range consists of single-stage liquid-ring vacuum pumps on a baseframe, equipped with a partial recirculation separator, or even a complete recirculation with integrated heat exchanger for maximum water savings.

Special constructions

Robuschi provides liquid ring vacuum pumps in in special construction for demanding applications in the chemical, petrochemical, pharmaceutical and other industries, covering the most stringent ATEX requirements with explosion proof design or closed circuit designs with special heat exchangers.
