Clean technologies are of particular importance in vacuum
technology – because they are economically advantageous and environmentally friendly.
With this in mind, Atlas Copco has developed the DZS 600 VSD+ and DZS 1200 VSD+.
The dry, oil-free claw pumps are powerful, energy-efficient and easy to control and
maintain. By using them, users can save costs, also because fewer resources are
consumed. Typical areas of application for the vacuum pump are CNC routing,
pneumatic conveying systems and central vacuum systems, for example in hospitals.
There, the oil-free, air-cooled DZS 600 VSD+ and DZS 1200 VSD+ series work reliably
over a long service life.
Non-return valve prevents backflow
“The DZS VSD+
are simple and modular in design,” explains Ahmed Elshaffie, the
responsible product manager. They consist of the pump and gear chambers, which are
separated by seals. Their energy-efficient, low-wear operation is based on a special
coating of the wetted parts and rotors as well as their simple operating principle. Two
claws rotate contactlessly in opposite directions in the pump housing. This draws air into
the pump chamber, compresses it and expels it again under pressure. In the gear chamber,
two gear wheels synchronize the claw rotation. The non-return valve in the inlet flange
prevents air from flowing back into the vacuum chamber when the pump is switched off.
The pumps are driven directly by a flange-mounted motor via a coupling.
Little installation space required
With their integrated VSD+
inverter drive with pressure setpoint control, the vacuum
pumps can be operated at high rotor speeds. The motor speed adapts to the process load
in an energy-efficient manner. “The DZS 600 VSD+
and DZS 1200 VSD+ models can run
continuously at their ultimate vacuum level without overheating,” adds product manager
Ahmed Elshaffie. Another important advantage is their variable use, as the compact
pumps take up very little installation space in rough vacuum applications.
Real-time access to important parameters
With the help of the Atlas Copco VSD+
app for iOS and Android devices, users can
control and monitor the DZS VSD+
series via their smartphone and thus access relevant
parameters in real time at any time. Another benefit: the app also makes it easier to
commission the series by setting the target pressure, start/stop delay and stop level. All
users have to do is start the pump, connect the VSD+
app via Bluetooth and enter the
desired parameters.
Proven use
“We have been using the robust, reliable claw technology in vacuum technology and
other areas for many years,” summarizes product manager Ahmed Elshaffie. With the
DZS 600 VSD+
and DZS 1200 VSD+ models, Atlas Copco therefore offers a simple,
reliable pump that can support customers in their processes for a long time without
interruption.
Important features of the DZS VSD+ models at a glance
• Vacuum relief valve: Prevents overheating in the ultimate vacuum over a long
running time
• Inlet non-return valve: Isolates the pump from the process when switching off
• The silencer reduces the noise generated by the pump in the working environment
• An integrated VSD+
inverter drive regulates the pressure setpoint
• The PEEKCOAT coating protects process-wetted parts and rotor
• Control at the touch of a button via the Atlas Copco VSD+
app.
