Refurbished Adixen by Pfeiffer Vacuum PASCAL 2005 SD Rotary Vane Vacuum Pump

The Adixen by Pfeiffer Vacuum PASCAL 2005 SD Rotary Vane Vacuum Pump is an oil-sealed vacuum pump designed for laboratory, analytical, research, and industrial vacuum applications. Manufactured under the Adixen and Pfeiffer Vacuum name, this pump belongs to the PASCAL series, which is designed to provide reliable vacuum generation for a range of processes requiring reduced pressure. The manufacturer's technical documentation identifies the PASCAL 2005 as a two-stage rotary-vane pump with a nominal pumping speed of 5 m³/h at 50 Hz and 6 m³/h at 60 Hz.

Rotary-vane vacuum pumps operate by using rotating vanes within an eccentric rotor to draw gas into the pumping chamber, compress it, and discharge it through the exhaust. In an oil-sealed design, the operating oil supports lubrication and sealing within the pumping mechanism. The two-stage configuration helps the pump achieve a deeper vacuum than many single-stage designs, making it suitable for applications that require low-pressure operating conditions.

The PASCAL 2005 SD can be used as a vacuum source for compatible laboratory instruments, vacuum chambers, analytical equipment, and industrial processes. Depending on the overall system configuration, it may support vacuum drying, degassing, laboratory research, leak detection setups, and other processes that require controlled pressure reduction. Its suitability for a specific application depends on the process gases, required vacuum level, operating conditions, and compatibility of the connected equipment.

The pump is designed with a compact, direct-drive configuration. This arrangement supports installation in suitable laboratory or industrial environments where a dedicated vacuum source is required. The PASCAL series also incorporates practical design features intended to support operation and maintenance, including oil-level monitoring and a gas-ballast function on applicable models. The gas ballast can help manage condensable vapours during pumping, although the ultimate pressure achieved depends on whether the gas ballast is open or closed and on the pump's operating condition.

The supplied photographs show an Adixen by Pfeiffer Vacuum PASCAL 2005 SD unit with a visible oil-level inspection window, adjustment control, and vacuum connection. The equipment appears to have signs of previous use. Before installation, the oil condition, seals, connections, motor, and pumping performance should be checked. The actual condition of the internal components and the pump's ability to reach its specified ultimate pressure cannot be established from photographs alone.

For laboratories and businesses looking for pre-owned vacuum equipment, this model may offer a practical option when its performance, maintenance history, and electrical configuration meet the intended requirements. Before purchase, buyers should confirm the exact motor voltage, phase, frequency, inlet and exhaust fittings, accessories, and service status. Different PASCAL 2005 SD configurations are available, so electrical specifications should not be assumed from the model name alone.

Whether used in a research laboratory, analytical testing facility, or industrial vacuum system, the PASCAL 2005 SD is intended to provide dependable vacuum generation when properly maintained and operated within the manufacturer's recommended limits. A functional performance test and inspection by a qualified technician are recommended before the pump is placed into routine service.
