MVP
Diaphragm vacuum pumps
MVP diaphragm vacuum pumps generate oil- and particle-free vacuum. They are available with two, three, or four stages, offering a broad selection for applications in the 1-10 hPa rough vacuum range, such as coating or vacuum distillation. Models with fewer stages provide higher pumping speeds for faster evacuation. Those with more stages achieve lower ultimate pressures because each additional stage compresses the pumped medium further, allowing the pump to generate higher vacuum levels.
Additionally, thanks to their compact size, MVP vacuum pumps are ideal backing pumps for turbomolecular vacuum pumps. Corrosion-resistant models featuring coated diaphragms and a corrosion-resistant pump housing enable safe operation when handling aggressive gases, for example in coating processes.

Benefits of the MVP series
MVP diaphragm vacuum pumps operate completely oil-free. Consequently, these vacuum pumps are ideally suited for applications requiring clean vacuum like mass spectrometry. Apart from generating vacuum, the diaphragm inside the vacuum pump functions as a hermetic seal between the compression chamber and the motor. This seal prevents potentially aggressive process gases from corroding the mechanical parts and avoids contamination of the pumped medium with operating fluids. Operating below 50 dB(A), diaphragm vacuum pumps offer low noise levels for sensitive environments like laboratories.
MVP diaphragm pumps are also available with direct current (DC) drive units, allowing them to run on batteries or DC power supplies. The DC motor is equipped with a variable speed drive. This feature allows the vacuum pump to adjust its rotational speed to the required vacuum levels, reducing energy consumption. Additionally, the variable speed drive enables the automatic boost mode, which can be activated to pump out volumes as fast as possible or to bring the pump up to temperature quickly when started. After five minutes or once a manually set vacuum level is reached, the vacuum pump will slow down.
Since the pump does not run at full speed when it is not required, wear is minimized, which leads to longer maintenance intervals. The reduced speed also results in low noise and vibration levels, ensuring a comfortable working environment.
The MVP models with DC motors are easy to integrate into existing vacuum systems. They can be connected to a HiPace turbomolecular vacuum pump, an external power supply, and the OmniControl unit via a 15-pin D-sub interface. The result is a complete vacuum system that not only generates high vacuum but also offers convenient process control.
Maintenance is required only every two years, when the diaphragm and valve can be easily replaced by the operator on site.
MVP vacuum pumps are available as corrosion-resistant versions, making them suitable for applications where the pump is exposed to aggressive gases, like in physical vapor deposition. These versions contain coated diaphragms and corrosion-resistant housing made of ethylene tetrafluoro copolymer.
