Type HR5 seals are outside mounted balanced seal, which require no shaft or sleeve step for balancing.
HR5 seal shows good performance in high vacuum conditions. Since no auxiliary equipments are needed for installation, it is very cost effective & economical.
These seal can be easily installed & repaired in the field to minimized replacement costs & downtime.
Main features of the HR5 dry running seals are:
* Simple, rugged drive design that withstands shaft movement vibration & deflection.
* Seal design eliminates the need of auxiliary equipments for cooling & lubrications for mixer application.
* It eliminates the possibility of product contamination, since there is no use of barrier fluid.
* Can be used in high vacuum applications.
These seals are very cost effective
Seals with bearing can be provided for Vessels having greater misalignments with special arrangement.

Mechanical seals are used for the sealing of rotating shafts against a stationary housing, e.g. in pumps and agitators. The stationary" part of the seal is usually located at the housing, the rotating" part is fixed on the shaft. The high-precision face-machined sliding faces rotate axially in opposition. The sliding faces are pressed against each other by means of spring force, thus preventing the opening of the seal. The seal faces are statically sealed against the housing and the shaft by secondary seals (O-rings). With the entry of the pumped medium into the minimal sealing gap a lubricating film is generated and the sealing effect is thus obtained.
The design, arrangement and combination of materials of the seal is basically determined by pressure, temperature, speed of rotation and quality of the pumped medium. Shaft diameters of 5...500 mm, pressures from 10 torr ....250 bar, temperatures from -200°C... +450°C and sliding velocities up to 150 m/s limit the operating range of mechanical seals. Additional seal supply systems or buffer fluid systems may be required, dependent on the mode of operation, the quality of the medium and the seal arrangement.

Stuffing Box Packings (Gland Packings) are machine-braided cords of different materials, used for sealing rotating shafts in pumps, ventilators and fittings. Packing sections are laid round the shaft in circles and then compressed with the gland. For dynamic applications, the compression must be so adjusted that a certain minor amount of leakage between packing and shaft may emerge. Harmful dry running is prevented thus and the leakage is dissipated or returned. Various materials and material combinations are used according to the individual case of application. Special lubricants are incorporated into the braiding to improve running properties.

PTFE gaskets are one of the most suitable types of gaskets for a variety of sealing applications and are mostly based on virgin PTFE, PTFE compounds, filled PTFE or expanded PTFE. And what provides the PTFE gaskets with such an extensive range of applicability? The answer is PTFE. PTFE is a fluoropolymere, which features an outstanding chemical resistivity to almost all chemicals, good thermal insulation properties, and useful mechanical and processing characteristics. The above-mentioned PTFE features can be usefully applied in PTFE gaskets. They can be mostly used in valve seats, bearings, requested to resin sliding and chemicals, elastic bands for an-lubricated compressors, O-rings where elastomers can not withstand.
An extended range of improved mechanical and processing properties can be additionally reached by a combination of virgin PTFE and different fillers.
Expanded PTFE Gaskets and Seal materials consist of virgin PTFE with multidirectional fibrous and/or porous structure, which the extruded PTFE consists of. A special manufacturing process provides the material with special chemical and physical properties. This can be of advantage in wide range of the applications.
Advantages
Virgin PTFE, PTFE compounds and expanded PTFE offer a wide range of compounded products with good mechanical properties, electrical properties, thermal properties, chemical resistance, low friction coefficient and good resistance to wear.
Shape and construction
Several types pf DONIT TESNIT® - PTFE gaskets are produced to meet the most demanding applications.
