Leybold DRYVAC DV 650 FP / FP-r – ready for daily wet cleaning

The DRYVAC DV 650 FP is designed for packaging and filling processes. Thanks to its hygienic design, according to Leybold it can be washed down together with the rest of the production line – without a stainless steel enclosure. The compact design and water cooling allow installation directly in the air-conditioned process area close to the machine, which reduces cycle times and installation costs. Key technical data: 650 m³/h maximum pumping speed, ultimate pressure ≤ 5 × 10⁻³ mbar without and 0.01 mbar with gas ballast, rated power 15 kW, power consumption below 10 mbar 6.6 kW, water vapour tolerance 60 mbar (with purge gas at the exhaust-side shaft seal), water vapour capacity 25 kg/h. Inlet flange DN 100 ISO-K, exhaust flange DN 63 ISO-K.

With or without cleanable stainless steel silencer

Leybold offers the FP-r without a silencer (1211 × 450 × 400 mm) or with an integrated, serviceable stainless steel silencer that needs no filling material, is self-draining and easy to clean. Both versions are available with LEYBONOL LVO 210 or with PFPE lubricant LEYBONOL LVO 410.

Typical applications

Vacuum packaging, filling and other processes in the food industry with daily wet cleaning; the pump can be flushed internally with liquids.
