Our oil lubricated rotary vane vacuum pumps are used in a wide range of industrial applications. We offer the largest range of oil flooded vacuum technology for industrial vacuum operation.
Oil flooded rotary vane vacuum pump with capacities from 6 to 11 cfm (10 to 24 m³/h), reaching an ultimate vacuum of up to 29.86 inHg (gauge) [2 mbar (abs.)]. This needs little space thanks to its overhung rotor design and integral motor. It is fitted as standard with a fine mesh filter, vacuum non-return valve and oil separator. This pump is ideal for any environment as it is very quiet running.
Oil flooded rotary vane vacuum pump with capacities ranging from 12 to 16 cfm (20 to 26.5 m³/h), and an ultimate vacuum of 29.86 inHg (gauge) [2 mbar (abs.)]. Designed especially for installation into small vacuum packaging machines. Features a flange mounted motor, bearings on both sides of the rotor and air cooling. Fitted with a fine mesh filter, vacuum non-return valve and oil separator.
Oil flooded rotary vane vacuum pumps with capacities ranging from 15 to 29 cfm (25 to 30 m³/h); V-VCE at 29.62 inHg (gauge) [10 mbar (abs.)]; flange mounted motor, bearings on both sides of the rotor, air cooling. Fitted as standard with fine mesh filter, vacuum non-return valve, gas ballast valve and oil separator.
Oil flooded rotary vane vacuum pump with capacities ranging from 30 to 903 cfm (40 to 1,535 m³/h), and an ultimate vacuum of 29.91 inHg (gauge) [0.5 mbar (abs.)]. Flange mounted motor, bearings on both sides of the rotor, oil/air heat exchanger. All models include aluminum alloy vanes, back pressure gauge, gas ballast valve(s), non-return valve and easy-access replaceable oil separators. Sizes of 400 m³/h and above include 5 micron paper inlet filter(s) and double-walled cylinder construction.
Oil lubricated rotary vane vacuum pumps are well suited for a variety of industries and applications including:
Pressure increase by volume reduction is the principle behind rotary vane operation. This design offers excellent service for pressure, vacuum or a combination of both. In a cylindrical housing (1) a rotor (2) is positioned eccentrically so that it is on the top almost touching the cylinder (3). Rotor vanes (5) are positioned inside rotor slots (4). When the rotor starts turning, due to centrifugal force from the rotors rotating, the vanes are thrown out and slide against the internal surface of the cylinder. In this way a cell (6) is formed between two vanes with a volume that changes constantly during rotation. Air enters from the inlet port (7) into a cell until the rear blade reaches the far end of the inlet port (8). At this point the cell (6) has achieved its maximum air volume. As the cell then moves away from the port its volume (9) becomes smaller and smaller, the air is thus compressed and the pressure rises. Some models are fitted with outlet valves (11) next to the outlet port (10) which stop the backflow of discharged air when the maximum pressure has been reached.
After its passage through outlet port (10) and outlet valves (11), the oil-gas mixture reaches the de-oiling pump chamber (12) where the oil is separated from the gas in two steps. Larger oil drops are mechanically separated from the gas and are eventually deposited in the oil sludge recipient (13). The remaining oil gas mixture is then taken through fine filter elements (14) which separate even the smallest oil particles. These are then reintroduced through an oil suction pipe into the pump‘s oil circuit. The virtually oil free gas can be let outside either through the air outlet (15) or through other hose or piping arrangements.
Our eco-friendly dry running rotary vane pumps are well suited for industrial vacuum, pressure and combined pressure and vacuum applications.
