Turbo-blower MVSC-D1120B3

The Marpa Vacuum MVSC-D series are two-stage side channel blowers and turbines. They are used in applications requiring high airflow. These pumps are designed for industrial applications where 24-hour pump operation is required. Maintenance is virtually non-existent thanks to lubricated-for-life bearings and a contact-free impeller. They are also easy to use. They are universally designed to operate in both vacuum and compressed air applications. When the blower is used in vacuum applications, the inlet must be connected to the application and the outlet to the atmosphere. When the blower is used in compressed air applications, the inlet must be connected to the atmosphere while the outlet will supply compressed air to the system. We strongly recommend using a pressure relief valve in both applications. - Applications: - Pneumatic conveying - Filling bags/bottles/tanks - Lifting and clamping of workpieces by vacuum - Aeration of wastewater treatment plants - Aeration of fish tanks - Thermoforming - Packaging machines - Paper processing - Food processing - Textile machines - Dental suction equipment - Gas analysis - Printers/photocopiers, laser printers - Swimming pool equipment/whirlpool baths Technical data: - Flow rate: 1.11 m³/h (50 Hz), 1.31 m³/h (60 Hz) - Max. differential pressure (overpressure version): 500 mbar (50 Hz), 430 mbar (60 Hz) - Max. differential pressure (vacuum version): -440 mbar (both frequencies) - Motor power: 20.0 kW (50 Hz), 23.0 kW (60 Hz) - Input voltage (3 phases) Δ: 345-415 V (50 Hz), 380-480 V (60 Hz) - Input voltage (3 phases) Y: 600-690 V (50 Hz), 660-720 V (60 Hz) - Input current Δ: 40.0 A (50 Hz), 42.0 A (60 Hz) - Input current Y: 23.0 A (50 Hz), 24.2 A (60 Hz) - Noise level: 74 dB(A) (50 Hz), 78 dB(A) (60 Hz) - Weight: 204 kg - Cooling system: Air - Gas inlet/outlet: 4" G(BSP) Key features / Technical specifications: - Two-stage side channel blower and turbine - High airflow for industrial applications - 24-hour continuous operation - Maintenance-free (lubricated-for-life bearings, contact-free impeller) - Usable for both vacuum and compressed air applications - Recommended use of pressure relief valve - Motor power: 20.0 kW (50 Hz), 23.0 kW (60 Hz) - Flow rate: 1.11 m³/h (50 Hz), 1.31 m³/h (60 Hz) - Max. differential pressure: 500 mbar (overpressure, 50 Hz), 430 mbar (overpressure, 60 Hz), -440 mbar (vacuum, both frequencies) - Input voltage: 345-415 V Δ / 600-690 V Y (50 Hz), 380-480 V Δ / 660-720 V Y (60 Hz) - Input current: 40.0 A Δ / 23.0 A Y (50 Hz), 42.0 A Δ / 24.2 A Y (60 Hz) - Noise level: 74 dB(A) (50 Hz), 78 dB(A) (60 Hz) - Weight: 204 kg - Cooling: Air - Gas inlet/outlet: 4" G(BSP)
