Slipper ptfe Composite seals

Products

SLIPPER:  Neuflon-ptfe compound seals

APPLICATIONS
In high speed and pressure fluid dynamics even in absence of lubrication, in analogical regulators and controllers, servo-systems and for all those uses where general high reliability is required

Double action sealing
Very low friction
No stick-slip
Installation in closed grooves and minimal encumbrance
Supplied in all sizes and many profiles
Long life

High reliability
Resistance to the "diesel effect"
Ample chemical and termal resistance
High extrusion resistance
No sticking
Parker O-Rings

HD Slippers Srl suggests the use of high quality Parker O-Rings within its Slipper Seal kits.

 

PRODUCTION PROGRAMME

Standard SLIPPER  N  series

  • Used in hydraulics and pneumatics
  • Max. pressur 800 bar and over in particular conditions
  • Speed up to 5 m/sec
  • Temperature range -60 a +200 °C

The N series is suitable for the most difficult conditions of use and the most extensive clearence
resizing is needed if installed in closed grooves

High Response SLIPPER  H  series

  • Used in hydraulics and pneumatics
  • Max. pressur 600 bar and over in particular conditions
  • Speed up to 5 m/sec
  • Temperature range -60 a +200 °C

The H series is suitable for the most difficult conditions of use and is suggested instead the N series when a faster response to the pressure is required
resizing is needed if installed in closed grooves.

Light SLIPPER series L

  • Used in hydraulics and pneumatics
  • Max. pressure 100 bar and over in particular conditions
  • Speed up to 5 m/sec
  • Temperature range -60 a +200 °C

The L series is the standard for use in pneumatics. It can be used in oleodinamics too, mantaining the clearance at a minimum

Ultra-Light SLIPPER series
Little encumbrance Slipper seal to fit O-Ring grooves

Used in hydraulics, pneumatics and chemical industry
Max. pressur 300 bar and over in particular conditions
Speed up to 5 m/sec
Temperature range -60 a +200 °C

When O-Rings stick, wear or extrude. It also allows the use in dynamic applications of O-Rings whose compound is for static sealing only

GUIDE TO CHOOSING THE RIGHT SLIPPER PROFILE

 slipper composite seals

 

Double action sealing. In dynamic applications it shows optimum sealing in both senses
 slipper composite seals Double action sealing. In dynamic applications it shows optimum sealing in both senses. more suitable for high speeds. At low speed and in static conditions this profile performs better than the preceding one
 slipper composite seals Single direction seal. In dynamic conditions it presents optimum sealing on the one hand and on the other it facilitates the return of the film of oil adherent to the sliding surface. Generally used for rod sealing in hydraulics applications

these profiles guarantee a longer life of the seal in conditions wherein constantly frequent levels of extreme pressure are reached

The technical-application data specified in catalogues, documentation and on this website are the result of more than forty years of experience and laboratory tests. The seal types suggested are the result of laboratory tests and thousands of field tests; however, the working conditions foreseen may not coincide with those of new applications and so lead to unexpected results. Therefore, HD Slippers Srl shall not be held responsible for the failure of sealing components that have not been tested under the actual working conditions. For new applications and the consequent manufacturing of specific seals, the user must conduct tests under the actual working conditions in order to approve the validity of the chosen solution. HD Slippers Srl guarantees the repeatability of the characteristics of seals tested and approved, except for subsequent modifications of applications and/or equipment and/or its components and/or processes, by the customer or a third part.
