⚙️ PVX SERIES – OIL-LUBRICATED ROTARY VANE VACUUM PUMPS
🔷 Product Overview
The PVX Series is a range of oil-lubricated rotary vane vacuum pumps that uses circulating oil to perform three essential functions:
➡️ Sealing the compression chamber
➡️ Lubricating moving components
➡️ Cooling the pump during operation
With deep vacuum capability, stable performance, and economical operating costs, the PVX Series is suitable for a wide range of industrial vacuum systems.
📌 Key Specifications
-
Pumping speed: 16–750 m³/h
-
Ultimate vacuum: 0.1–1 mbar
-
Motor power: 0.55–18.5 kW
-
Frequency: 50 Hz or 60 Hz
-
Noise level: 64–76 dB
-
Oil capacity: 0.4–22 litres
-
Inlet connection: ½ inch to DN100
🔄 Operating Principle
The rotor is mounted eccentrically inside the pump chamber and works together with sliding vanes.
As the rotor rotates:
➡️ The inlet chamber volume increases, creating vacuum and drawing gas into the pump.
➡️ The gas is trapped between the vanes and progressively compressed.
➡️ The compressed gas is discharged through the outlet.
The circulating oil improves chamber sealing, reduces friction, removes heat, and helps maintain stable vacuum performance.
An advanced oil mist separator separates oil from the exhaust gas and returns the recovered oil to the lubrication circuit for reuse.
