4-Cylinder Small Membrane Linear Pump PB 5

The oil-free and dry compressing small membrane linear pumps of the PB-5 product line are designed for evacuating and compressing gases and vapors down to an ultimate vacuum of 3 mbar. Within the product line, nine different series with additional unique models are offered. (Curve representation of the standard models per series). The PB-5 product line is equipped with a four-cylinder membrane pump with linear drive. The wobbling and walking of the membranes is avoided here during the precisely linear up and down movement between the upper and lower dead points. This results in a high lifespan of the membrane. Compared to crankshaft pumps, membrane pumps are more compact due to the elimination of rigid and long connecting rods while maintaining comparable performance. Quiet operation, proven long service life, and maintenance-free operating time further characterize this series. The materials used, such as aluminum for the gas-conducting components,...
