/h. These energy-efficient and
reliable pumps are ideal for use in deman-
ding processes in the semiconductor and
coating industries. With corrosion resis-
tant materials and a high gas throughput,
this pump series is optimally suited for use
in CVD processes, for example.
Turbopump HiPace 2800 IT
:
With the HiPace 2800 IT Pfeiffer Vacuum
presents a turbopump especially dedica-
ted for ion implantation applications. The
sophisticated rotor design of the turbo-
pump results in an optimized pumping
speed for light gases. This ensures very
good process adaption for ion implantati-
on processes, were hydrogen is the most
accumulating gas. With 2,750 l/s pum-
ping speed for hydrogen the new HiPace
2800 IT is the best turbopump in its class.
The intelligent temperature manage-
ment system prevents process condensa-
tion and deposition inside the pumping
system. It allows setting the temperature
individually to ideally support the pro-
cess. The special coating of the rotor en-
sures robustness against all ion implanta-
tion process materials. Being based on a
so-called hybrid bearing, a combination
of ceramic ball bearings on the fore-va-
cuum side and permanently magnetic ra-
dial bearings on the high vacuum side,
these HiPace turbopumps have a parti-
cularly robust bearing design. Together
with the efficient coating, this forms the
basis for the long life cycle and maxi-
mum up-time of the pumps.
Magnetically levitated turbopumps
ATH 2804 M and ATH 3204 M
:
The ATH-M pumps offer a gas
throughput of over 5,000 sccm of nitro-
gen for non-heated applications. They
also allow a very high throughput with
up to 1,500 sccm of argon and a pump
operating temperature of 65 °C in corro-
sive applications. The pumps operate at
high temperatures up to 85 °C for use in
the most aggressive applications with by-
product deposition sensitive processes.
These pumps include integrated drive
electronics to ensure a small footprint
and easy plug-and-play installation. The
total height of the DN 320 flange model
is less than 400 mm. Due to the new
electronics, the pumps can be started
and stopped within eight minutes. Ac-
tive magnetically levitated bearings and
automatic out-of-balance compensation
enable wear-free and low vibration ope-
ration of the ATH-M pumps. They are
maintenance-free and require no lubrica-
tion. Continuous rotor stability is assured
for reliable performance. Low power
consumption at nominal speed and very
low cooling water consumption (1 l/min)
also characterize the new ATH-M pumps.

美国Advanced Plastic Extrusion有
限公司(简称Apex)最近安装了戴维斯
标准公司(Davis-Standard )所生产的
片材系统,设备已投产运行,并获得了
极为完美的结果。Apex公司位于美国北
卡罗莱纳州,是一家新成立的公司,致
力于高质量片材的制造,生产“A级”表
面的专用片材和复合片材。Apex公司从
九月份开始生产片材,已经加工了亚克
力(丙烯酸)、ABS、HIPS、PC/ABS
和TPO等各种树脂原料,产品的厚度范
围从0.010到 0.187英寸,宽度可达54
英寸。从技术和服务的角度来看,戴维
斯标准所提供的系统,包括挤出机和辊式
压光机,是Apex公司取得成功不可分割
的一部分。
APEX公 司 的 创 始 人 和 所 有 者
Ronnie Buck指出 :“在考察了好几家挤
