Description
OVERVIEW
GAS BOOSTER FOR LOW PRESSURE APPLICATIONS
The GMd series, made by AERZEN, is the universal gastight booster solution for the low pressure range. Equipped with a magnetic coupling, it ensures a 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.
DESIGN
Nodular iron, steel casting or stainless steel. Housing with circular flanges and O-ring seals.
SEALINGS
Shaft sealing by hermetically sealed magnetic coupling. Alternatively oil-purged double-acting mechanical seal with thermosiphon cooling for torques ≥ 550 Nm.
DIRECTION OF FLOW
Vertically downwards.
DRIVE
Direct coupling with motor (design B35 for magnetic coupling or B3 for alternative shaft sealing via mechanical seal).
BOOSTER DESIGN
- Max. pressure increases from 1.0 bar abs. to 7.0 bar abs.
- Housing pressure proof for PN 25 with O-ring seals
- Oil splash lubrication
- Separation of the oil chambers and the conveying chamber by PEEK piston ring seals, gas shut-off possible

APPLICATIONS
PROCESS GAS BLOWERS FROM AERZEN WORK RELIABLY IN ALL INDUSTRIES AND IN ALL MARKETS AND COUNTRIES OF THE WORLD.
AERZEN offers the process gas and refrigeration industry an enormously wide range of blower technologies – perhaps the widest ever. The machines work in a stand-alone manner, in a machine or container combination, onshore and offshore. You find them in really all key industrial applications.
