The RUVAV WH2500 pump.

 

The DRYVAC DV450 is part of the company’s DRYVAC range and combines dry screw technology with a compact design. It also has quiet operation, low ambient temperatures and minimal cooling water consumption. The DV450 is a smaller version of the DRYVAC DV650, with an drive for suction speeds of 450m3/h and an engine efficiency with only 5.3kW power consumption at final pressure. The integrated frequency converter leads to reduced installation efforts for customers with full pump protection and a large variety of interfaces. Another benefit for demanding processes is the operation at very low screw-rotor temperatures, which makes the pumps suitable for applications such as solar lamination.

The RUVAC WH2500 features flexibility and pump protection due to being operated with a frequency converter. It has a small footprint and low power consumption, along with minimized noise and heat emission. The pump can be directly mounted onto properly sized backing pumps of Oerlikon Leybold Vacuum. It is available with two different oil fillings – either synthetic oil or PFPE oil. The new WHU2500 with by-pass valve features a new motor concept which helps to reduce pump down time in short cycle applications.
