MVC Series

The MVC series of rotary claw pumps is ideal for low-vacuum industrial applications. Marpa Vacuum MVC pumps have a compact and efficient design that provides high reliability and durability, as well as noise reduction thanks to optimised sound insulation. This noise reduction allows the pumps to be used at workstations. The series is highly efficient and can reduce overall running costs by up to 50% compared to conventional vacuum generators. Thanks to the pumps’ compact, air-cooled design, they are easy to install on small surfaces and do not require water. They are direct driven and do not require belts. An anti-suction valve and a pressure regulating valve come standard on the pumps.

Operating principle

Marpa Vacuum dry-running claw vacuum 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 the vacuum chamber is not moving. Claw vacuum pumps are directly driven by a flanged motor, and the two pistons are synchronised by gears.
