Leybold RUVAC WH 7000 – water-cooled Roots pump with 7000 m³/h nominal pumping speed
With 7000 m³/h nominal pumping speed, the RUVAC WH 7000 is the largest pump in the WH series; with a frequency converter it reaches up to 9800 m³/h at 70 Hz. The DN 320 ISO-K inlet flange is designed for large chambers, the reduced DN 160 ISO-K outlet flange for direct mounting on the backing pump. 11 kW and 18.5 kW motors, heavy-duty versions with purge gas and oil fillings with ester oil or PFPE are available. The nominal pumping speed is 7000 m³/h at 50 Hz and 8400 m³/h at 60 Hz, the maximum effective pumping speed 4700 and 5300 m³/h respectively. In the standard version the pump measures 1433 × 540 × 414 mm, weighs 650 kg and is connected via DN 320 ISO-K (inlet) and DN 160 ISO-K (outlet); the noise level is below 63 dB(A).Typical applications
Leybold developed the WH series for applications with high demands on operating pressure, cycle time and system availability: display production, solar industry, furnace construction, industrial coating, research and space simulation. The pumps work as boosters in front of dry backing pumps of the DRYVAC, SCREWLINE and LEYVAC series or in front of oil-sealed SOGEVAC pumps.Variants of the RUVAC WH 7000
The RUVAC WH 7000 is available from Ehrler & Beck in 19 variants (part numbers 1227700V14, 1227700V19, 1227700V24, 1227700V13, 1227700V10, 127700V14, 127700V19, 127700V24, 127700V29, 127700V13, 127700V10, 127700V20, 155160, 155161V, 155165, 155164V, 155167, 155163V, 167194V). The motor power ranges from 11 kW to 18.5 kW. Available oil fillings: ester oil LEYBONOL LVO 210, PFPE LEYBONOL LVO 400. Several part numbers describe the same version: Leybold has changed the numbers of the series twice, so the numbers from the catalogue, the current operating instructions and the web shop are listed together.Features of the RUVAC WH/WHU
