Diaphragm Vacuum Pump

Diaphragm vacuum pumps

Diaphragm vacuum pumps, also known as dry displacement pumps, are recognized for their unique design and efficient operation. These pumps utilize a craft shaft that drives a connecting rod, causing the Diaphragm to move back and forth. The Diaphragm is securely tensioned between the housing and headcover, creating a sealed suction chamber.

The suction chamber, located between the Diaphragm and headcover, plays a crucial role in the functioning of the diaphragm vacuum pump. Gas displacement occurs through the operation of outlet and inlet valves. The valves are typically made of elastomeric materials and act as pressure-controlling shutters. The Diaphragm initially pulls downward, creating a low-pressure environment within the suction chamber. This low pressure causes the inlet valve, also known as the left valve, to open, allowing gas to be drawn into the chamber. Conversely, the right-side valve, subjected to higher pressure, remains closed.

The Diaphragm drive effectively seals the suction chamber, preventing aggressive or contaminated media from damaging the internal mechanics of the pump. This design feature ensures that the pump can handle clean and non-corrosive gases efficiently. The compression ratio, the ratio of outlet pressure to inlet pressure, is limited due to the confined space between the suction chamber and outlet valve. Typically, a single pump stage can achieve a maximum pressure of approximately 70 mbar. If additional pumping stages are added, the pressure can be further reduced to as low as 0.5 mbar.

It is important to note that in this type of Diaphragm pump, there is no provision for generating lower pressures. The force exerted is insufficient to open the inlet valve under such conditions. Therefore, the pump is not suitable for applications requiring extremely low pressures.

Diaphragm vacuum pumps offer several advantages in various industries and applications. The dry displacement design eliminates the need for oil lubrication, making them clean and environmentally friendly. Their compact size, quiet operation, and reliable performance make them well-suited for laboratory use, medical equipment, analytical instruments, and other precision applications where a clean and oil-free vacuum source is required.

In summary, Diaphragm vacuum pumps are dry displacement pumps that operate by utilizing a Diaphragm connected to a craft shaft. These pumps create gas displacement through the operation of outlet and inlet valves. The suction chamber, sealed by the Diaphragm, allows gas to be drawn in through the inlet valve while preventing aggressive or contaminated media from damaging the internal mechanics. With their reliable performance and oil-free operation, Diaphragm vacuum pumps serve as valuable tools in various industries where a clean and efficient vacuum source is essential.
