Double stage rotary vane vacuum pumps. Two stage rotary vane pumps are suitable for applications in the low and medium vacuum ranges down to a pressure of 10 3 hpa.

Two stage rotary vane pumps can be used in the pressure range between 100 hpa and a pressure roughly a decade above the final pressure. The entire pump operation is interrelated and therefore not suitable for removing oxygen containing toxic explosive etched ferrous metals. Rv two stage rotary vane pumps a compact multipurpose pump with superior vapour handling capabilities our rv series rotary vane pumps are rugged pumps that offer you an excellent ultimate vacuum with good pumping speeds as well as superior vapour handling capabilities and quiet operation.
