The oil-free and dry compressing small piston pumps from the PB-22 product line can be used for evacuating, conveying and compressing gases and vapours up to a final vacuum of 27 mbar. Eight different ranges with further unique models are available within the product line. (Curve presentation of the standard models, per model range).
The PB-22 product line is equipped with a two-cylinder piston pump with linear drive. The straight guidance of the piston in the cylinder, between top dead centre and bottom dead centre, ensures that the piston sealing rings are evenly loaded all around. In contrast to the tilting movement, this achieves a long service life for the piston sealing rings and reliable sealing between piston and cylinder wall.
The materials used, such as aluminium for the gas-conducting components, stainless steel for the valves and piping and VITON (FKM) for the diaphragms, open up a wide range of application options with non-aggressive gases.
