The variety and application possibilities of AERZEN process gas blowers are unrivalled anywhere in the world. Now a new GMd series is available that bundles many variants and leaves no wish unfulfilled.

In the AERZEN zero-emission concept, the small GMd sizes do not have a drive shaft seal, but only the can of the magnetic coupling, which serves for torque transmission. The cans of the magnetic couplings are made of non-conductive materials, so that even at high speeds there are no eddy currents and associated heating.
Cost advantage without any loss of quality
On larger machines, the drive shaft is reliably sealed by an oil-purged dual-acting mechanical seal with thermosiphon cooling. Thanks to the oil splash lubrication of the roller bearings and the timing gears, separate pressure oil lubrication is not required. This results in a cost advantage without any loss of quality. The robust, two-lobe rotary pistons are always sealed gas-tightly. The oil chambers and the conveying chamber are separated by PEEK piston ring seals. It is also possible to purge these seals with gas. With a total leak rate of <10-³ mbar*l/s, all blower stages of the GMd series can be described as hermetically sealed. The housing flanges are sealed with O-rings. With a design pressure of 7 bar(g) and explosion pressure spike resistance of 13 bar(g), the nodular iron housing ensures particularly high operational reliability.The modular system of the new “GMd” generation consists of 16 sizes.
