The oil-free and dry compressing small piston pumps from the PB-37 product line can be used for evacuating, conveying and compressing gases and vapours up to a final vacuum of 180 mbar. Three different ranges with further unique models are available within the product line. (Curve presentation of the standard models, per model range).
The PB-37 product line is equipped with a single-cylinder diaphragm pump with con-rod drive, which carries out an oscillating, tumbling and rocking, upwards and downwards movement of the diaphragm. The diaphragm is fastened to a rigid con-rod and is subjected to a greater or lesser degree of flexing and stretching, depending on the length of the con-rod. The well-thought-out design of the drive offers the user a compact construction and low spatial requirements.
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.
