Rotary claw vacuum pump MVC-1005

oil-freeanti-corrosionair-cooled

The Marpa Vacuum MVC series pumps operate on the principle of two single-stage rotary pistons. Two rotating pistons rotate 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, the air is drawn in through the suction port, compressed in the compression chamber and then expelled through the exhaust. The 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. - High pumping speed - Oil-free pumping chamber - Corrosion protection by Teflon coating - Air cooling, no water required - Maintenance requirements minimised - Rotation of the claws without contact - Direct drive - Anti-suction valve to ensure vacuum Technical data: - Flow rate/volume flow: 950 m³/h (50 Hz), 1140 m³/h (60 Hz) - Ultimate pressure: 50 mbar (both 50 Hz and 60 Hz) - Ultimate vacuum at continuous operation: 180 a atm.
