Rotary claw vacuum pump MVC-0305

lubricatedsingle-stagesuction

The Marpa Vacuum MVC-0305 is part of the MVC Series of vacuum pumps, operating on the principle of two single-stage rotary pistons. Two rotating pistons move in opposite directions inside the pump. The special geometrical shape of the claws allows the suctioned air to be compressed inside the vacuum pump. As the rotors rotate, air is drawn in through the suction port, compressed in the compression chamber, and then expelled through the exhaust. A non-return valve, fitted as standard on the suction port, prevents air from flowing back into the vacuum chamber when it is not moving. Claw vacuum pumps are directly driven by a flanged motor, and the two pistons are synchronised by gears. Gear oil is used to lubricate the claws. Both the claws and the compression chamber are coated with TFE (Teflon) to protect the pump against corrosion from any gases sucked into the pump.Product dimensions:ModelLWHABCDEFGIJMQMVC-03059755016851034901802523982791666602"2"M10 TapTechnical data:Technical dataUnits50 Hz60 HzFlow rate/volume flowm3/h300360Ultimate pressurembar5050Ultimate vacuum at continuous operationmbar180 a atm.180 a atm.Motor powerKw5.56.6Nominal motor speedrpm28503450Noise leveldB(A)7880Oil tank capacityLt0.90.9Weight approx.Kg235248Permissible ambient temperatureºC5-405-40Gas inletG(BSP)2”2”Gas outletG(BSP)2”2”User benefits:High pumping speedOil-free pumping chamberCorrosion protection by Teflon coatingAir cooling, no water requiredMaintenance requirements minimisedRotation of the claws without contactDirect driveAnti-suction valve to ensure vacuumKey features / Technical specifications:Two single-stage rotary pistonsSpecial geometrical claw shape for efficient compressionNon-return valve on suction portDirect drive by flanged motorGear synchronisation of pistonsGear oil lubricationTFE (Teflon) coating for corrosion protectionFlow rate: 300 m³/h (50 Hz), 360 m³/h (60 Hz)Ultimate pressure: 50 mbarMotor power: 5.5 kW (50 Hz), 6.6 kW (60 Hz)Noise level: 78 dB(A) (50 Hz), 80 dB(A) (60 Hz)Oil tank capacity: 0.9 LWeight: 235 kg (50 Hz), 248 kg (60 Hz)Permissible ambient temperature: 5-40 ºCGas inlet/outlet: 2” G(BSP)
