Atlas Copco, based in Stockholm, Sweden, recently launched a new series of speed-driven screw pumps in three pumping speed classes.
Building on its GHS VSD+ range of variable speed-driven oil-injected screw vacuum pumps, the new GHS 1402-2002 VSD+ series of pumps features a new design for better performance, optimal oil separation, a smaller footprint, and an innovative new controller.
In rough vacuum applications, the oil-injected pumps deliver a continuously high pumping speed from atmospheric pressure to ultimate pressure. They are ideal for central vacuum systems, vacuum cooling, the production of food packaging and thermoformed plastic components, and vacuum chambers for altitude simulation.
Compared to the previous models, the innovative design of the GHS 1402, GHS 1602, and GHS 2002 VSD+ results in better vacuum performance, a 15% smaller footprint, and longer maintenance intervals.
The new GHS VSD+ screw pump also saves energy costs based on the combination of the Neos inverter with a setpoint control. This means that the GHS 1402-2002 VSD+ pumps deliver exactly the pumping speed required for the process. An energy recovery system helps recover up to 80% of the power in the form of hot water, resulting in lower CO2 emissions.
The increased efficiency is also due to the new permanent magnet motor. In its IE5
efficiency class, it produces an increase in efficiency of about 2% over the entire speed range.
Oil cooling maintains the optimal motor temperature at all speeds. The motor bearings are also lubricated by oil, which eliminates the need for regular relubrication. The motor is enclosed in a housing with IP66 protection.
One of the more exciting features of the GHS 1402-2002 VSD+ series is its intelligent
functionalities. Via the controller, users can visualize and set the parameters from any smartphone, laptop, PC, or tablet via a web browser, regardless of location. This allows the vacuum pumps to be configured even more specifically and sustainably for the respective application.
