Single-stage rotary vane pumps from Pfeiffer Vacuum have long been some of the most widely used products for processes in the low and medium vacuum range. Their long life and pumping speed, irrespective of the gas used, are the outstanding properties of this pump. Typical applications are found in widely ranging sectors: — Analytics (mass spectrometry, electron microscopy) — Coating technology (surface protection, decorative films, display units, monitor screens) — Vacuum metallurgy (vacuum soldering, vacuum sintering, vacuum alloys, furnace construction) — Leak detection technology (vacuum systems, automotive tanks, airbag cartridges, packaging) — Lighting industry (light bulb manufacture) — Drying industry (vacuum drying, transformer drying)

Measurement and control In this sector, MPT represents the interests and products of WALCHEM Corporation in Holliston, Massachusetts (USA). WALCHEM is a leading manufacturer of sensor technology and controllers for the surface technology and for the water treatment technology, including pH-, redox and conductivity controllers as well as special controllers for the cooling-water and boiler water conditioning. Besides the measuring transducer, these controllers include also a control program, adapted to the respective application. Monitoring, alarming – control and telecontrol systems By default, WALCHEM’s WebMaster has available sensors and data amplifiers for various physical parameters. Using the integrated program the parameters can be linked to each other and to control parameters. Via telephone modem and Ethernet board the user is provided with information such as alarm messages and off-limit conditions worldwide.  Measuring and control technology for dosing liquid media in

PU composites are mainly found in the production of moulded parts resistant to bending. The skilful combination of materials puts the topic of lightweight construction into the spotlight (honeycomb technology applications). Sophisticated surface designs are supported by corresponding PU / UP resin systems. Thanks to the reduced component weight, moulded part applications are used in the automotive sector – and, with corresponding flame protection formulations, also in rail vehicle construction. Typical properties Moulded part density of 450–1100 kg/m³ Fibre proportion from 30 % Available foaming agents: usually water Reinforcing materials Glass fibre rovings Glass fibre mats and non-crimp glass fibre fabrics Carbon fibres Natural fibres (hemp, sisal, coconut etc.) Special formulations and versions Honeycomb materials for sandwich structure components Paper honeycombs Waterproof paper honeycombs (patent-pending process) Plastic honeycombs Aluminium honeycombs Systems with a large processing window Use of polyols based on renewable resources Self-parting with simultaneous good lamination properties Flame protection formulations Automotive: FMVSS 302 Rail vehicle construction: DIN 5510 (S4, SR2, ST2) Aircraft construction: FAR 25853, ABD 0031 Construction industry: DIN 4102 B2
