Aerzen - Model Series GMD -Low Pressure Gas Booster

The GMD series from AERZEN is the universal gastight booster solution for the low-pressure range. Equipped with a magnetic coupling, it guarantees a virtually maintenance-free sealing concept. Locking systems for sealing the drive shaft are completely eliminated and allow a low-maintenance machine concept. The separation between oil and process side is achieved by a special piston ring seal. The robust two-lobe design allows a design pressure of 7.0 barg according to AD2000/DIN EN 13445. 16 sizes guarantee optimum efficiency and operation conditions for every design case.

Nodular iron or stainless steel housing with round flanges and O-ring seals.

Shaft sealing by hermetically sealed magnetic coupling. Alternatively oil-purged double-acting mechanical seal with thermosiphon cooling for torques ≥ 600 Nm.

Vertically downwards.

Direct coupling with motor (type of construction B35 for magnetic coupling or B3 for alternative shaft sealing via mechanical seal).

• Max. pressure increases of 1.0 bar
