Back2-Cylinder Small Diaphragm Pump PB 4

Description

The oil-free and dry compressing small diaphragm pumps from the PB-4 product line can be used for evacuating, conveying and compressing gases and vapours up to a final vacuum of 12 mbar. Four different ranges with further unique models are available within the product line. (Curve presentation of the standard models, per model range).

The PB-4 product line is equipped with a two-cylinder diaphragm pump with linear drive. The staggering or flexing of the diaphragms is prevented here with precisely-straight upwards and downwards movement between the top dead centre and bottom dead centre. This ensures a long service life for the diaphragm. When compared to con-rod pumps with the same performance, diaphragm pumps are a more compact construction due to the omission of the long and rigid con-rods.

The range is further distinguished by quiet operation with proven long service life and maintenance-free operating time.

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.
