 II Simmerring series HTS stands for "high temperature and speed" was specially developed for operative ranges that are characterized by high temperatures of up to 200 AC and circumferential circumferential /cir·cum·fer·en·tial/ (-fer-en´shal) pertaining to a circumference; encircling; peripheral.  speeds of up to 25 m/s.

Now, a standard series of six different designs is available for sealing process engineering plants. These six different designs cover almost all conventional requirement profiles in different units. If necessary and required, individually adapted designs can be machined to provide special solutions.

The Simmerring Radiamatic HTS II, an incredibly reliable, friction-minimized PTFE PTFE

 radial shaft seal Radial shaft seals are used to seal rotary elements, such as a shaft or rotating bore. Common examples include strut seals, hydraulic pumps seals, axle seals, power steering seals, and valve stem seals. , has been on the market for over ten years now. Developed to be manufactured on an individual basis, it was initially used to seal highly sophisticated applications in the processing industry. With its PTFE/stainless steel material combination and special design, this radial shaft seal offers four specific advantages:

a specially adapted sealing lip geometry,

various uses for PTFE materials in the food & beverage and pharmaceutical industries,

easy installation (the seal is simply pressed into the open housing bore),

adaptability to the available installation space.

The outstanding advantages of this radial shaft seal are now available as standard in the following six different designs for process engineering units and plants:

with a standard lip for conventional applications,

with an additional dust lip for applications in highly soiled environments or for use in alternating pressurized/vacuum operation,

with a double sealing lip for applications with high safety requirements,

as a clearance volume-free version with a sealing lip that has been moved closer to the medium for applications that meet the requirements of Hygienic hy·gien·ic

 requirements, and

as a short sealing element for the tiniest installation spaces.

In all cases, the sealing lip is designed to ensure that the exactly defined contact area remains almost entirely constant in all operating conditions. The special lip profile optimizes contact forces in a way that allows the sealing force to increase as pressure rises and triggers a reforming action on the sealing lip when temperatures rise. In this way, the Radiamatic HTS II guarantees outstanding sealing performance even at high circumferential speeds or pressures. At the same time, friction and wear are reduced to such an extent that the excellent emergency running properties of this type of seal have a negligible effect on service life in the event of dry running. On average, the service life of a Radiamatic HTS II seal is about 50 percent longer than that of conventional radial shaft seals.
