The oil-free and dry compressing piston pumps from the PB-36 product line can be used for evacuating, conveying and compressing gases and vapours up to a final vacuum of 90 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-36 product line is equipped with a single-cylinder piston pump with con-rod drive. The piston, rigidly fixed to the con-rod, carries out a tilting motion in the cylinder when moving up and down. The piston rings are therefore more heavily stressed than with a linear drive. The length of the con-rod from the eccentric shaft to the piston is however designed to impart as small a tilting motion as possible to the piston. The eccentric shaft with con-rod is additionally ball-bearing mounted in the carrier plate and does not sit on the motor shaft. This ensures that the motor shaft and the A-side motor bearings are not loaded. This well-thought-out design also ensures a long service life for the mechanical components.
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.
