UTECH 2018: Holding companies present solutions for the polyurethane industry
VSE showcased the modification of its preamplifier VSI. The further development of the previous electronics leads to a highly improved signal quality with harmonious impulse widths. Therefore, more constant and vibration free measurements can be achieved. Besides, the interpolation factor has been increased by two IPF factors (24 and 32). Due to the interchangeable system, existing systems can be easily retrofitted or extended and standardised. An integrated embedded system enables more flexibility, so customised solutions are also quickly feasible. Besides this innovation, VSE also highlighted its RS screw flow meter in standard and high temperature version.
With DST permanent magnetic couplings leakages are prevented. Especially in applications with critical, highly toxic or aggressive media, hermetically sealed drives are inevitable. DST permanent magnetic couplings offer a reliable alternative to conventional dynamic seals due to their contactless and leakage-free torque transmission in pumps and agitators. Besides the standard ranges and more than 1000 magnet configurations, further customer-specific solutions are also available.
The DST conversion kits can be retro-fitted in many areas, for example in PU machines or for hydraulic applications and allow a combination with all leading makes of pumps and drive motors. On request, the conversion kits can also be supplied with foot flange, damping elements and sensor monitoring (PT100, speed and leakage monitoring).
Beinlich presented its external gear pumps ZPD and ZPDA. Case-hardened, in tool steel or ADLC coated, these pumps are wear-resistant and suitable for media with fillers.
The pulsation-free ZPD pumps can be applied as feeding pumps from the tank storage but also as dosing pumps or in blending stations for amines, catalysts, hardeners, iso and much more. They are available in many different material pairings (stainless steel) and as drum drainage pumps. In low speed version, the high-precision gear dosing pump ZPDA can dose smallest amounts of different viscosities up to 200 bar.
