Introduction to Claw Pumps
Claw pumps are a type of dry vacuum pump that operate on the principle of positive displacement. They consist of two or more rotating claws that intermesh without touching each other. This design allows for the efficient transfer of gas from the inlet to the outlet, creating a vacuum in the process. Claw pumps are known for their oil - free operation, which makes them suitable for applications where oil contamination is a concern, such as in the semiconductor, pharmaceutical, and food industries. They also offer high pumping speeds, low maintenance requirements, and long service lives.
