Aesseal customer training dates announced
Aesseal Plc, a company that designs and manufactures mechanical
seals, has announced the dates for the customer training sessions that are being held at its corporate headquar-ters in the UK – the Global Technology Centre, in Rotherham.
The firm says that the training provides attendees with essential knowledge covering mechanical seals, seal support systems and cen-trifugal pumps – to help advance and improve equipment reliability.
Customer training is fully inclusive and a typical two-day session includes two full days of training in rotating equipment reliability, two nights of high-quality accommodation, with full evening meals and buffet lunches, evening leisure activities and all transportation, including taxis and coach hire for the duration of the course.
Aesseal says that spaces are allocated on a first-come first-served basis so book early to avoid disappointment. To book, request a regis-
tration form by email from Katie Burgin at the address which appears below.

PPE workshops focus on elastomer technology and seal design
UK-based Precision Polymer Engineering Ltd (PPE), which
designs, develops and manufactures moulded rubber seals, and rubber gas-kets and components, is conducting a range of professional development training courses and workshops that focus on the important aspects of elas-tomer technology and seal design.
These educational events include industry-specific courses and are based on a combination of interactive activities, group and individual exercises, case studies, hands-on problem solving tasks and discussions, along with formal techni-cal input from experienced course trainers.
The courses available are listed below:
‘An Introduction to Elastomer Materials and How O-Rings Work’ (half-day course);
the Oil and Gas ‘Industry’ (one day);
the Semiconductor Industry’ (one day);
Diesel/Aero-Engine Industry’ (one day); and

PTFE lip seals – design guidelines for bidirectional sealing aids
The elastomeric radial lip seal is commonly used to seal rotating shafts, but high temperatures, chemically aggressive fluids and dry-running con-ditions harm and destroy the elastomeric material. To avoid these problems seals made from polyte-trafluoroethylene (PTFE) were developed.
PTFE is resistant to heat and chemicals and can run dry. Unlike elastomeric radial lip seals,
ones made from PTFE do not pump back fluid automatically. To seal crankshafts a PTFE lip seal with a spiral groove was invented. However, this sealing aid only pumps back fluid in one rotational direction and is not leak-tight under static conditions when (partly) flooded, which means that it cannot be used in all applications.
PTFE lip seals with bidirectional sealing aids are currently not available on the market. However, research that is being done at the Institute of Machine Components (IMA), at the University of Stuttgart, aims to develop such structures for PTFE lip seals.
