Merkel Chevron Seals

 

 

 

 

 

 

 

 

The roof flange sets of Freudenberg Sealing Technologies consist of a pressure ring, one or more collars and a support ring: The multi-part sealing sets are particularly well-suited for robust areas of application, such as the supply of spare parts for old systems. The roof flange sets persuade due to their long service lives. The sealing sets can be used for pistons that are pressurised on one side or on two sides – back to back.

PRODUCT DESCRIPTION

Multi-component Merkel seal set for sealing piston rods, consisting of a pressure ring, at least 3 seals and a back-up ring. The Merkel Chevron Seal Sets are available in 3 different designs. Type A has 3 to 5 fabric roof-shaped seals and can be installed in adjustable or non-adjustable sealing areas. Type B has 3 to 5 fabric roof-shaped seals, one rubber-sprung back-up ring and is installed in non-adjustable sealing areas. Constant axial pre-load. Type C has 2 to 4 fabric roof-shaped seals, one rubber seal and can be installed in adjustable and non-adjustable sealing areas. For an enhanced sealing effect. Type A and Type B can be supplied in open form. Type C is always delivered in endless form.

PRODUCT ADVANTAGES

Seal set for robust operating conditions, mainly for provision of spare parts to old plant.

  • Proven under extreme conditions
  • Long service life
  • Can be optimally adjusted to the related application
  • Functions over a certain time period even with poorer surfaces
  • For application and design-related reasons fluctuations in the leakage behaviour and friction behaviour are to be expected

PRODUCT DESCRIPTION

Merkel V-packings are used for sealing piston rods, plungers and in exceptional cases of pistons. With their robust design they are very suitable for use in highly demanding, heavy and horizontal compressors, particularly if the plungers are subject to large side forces. V-packings can even be used if piston rods or plungers cannot be correctly used because of wear. V-packing in connection with fabric pressure and back-up rings are used primarily in heavy-duty hydraulics because they can easily be tightened at any time and their robust design. V-packing rings are supplied open for nominal diameter up to an inside diameter of 400 mm. For larger diameters the rings are over dimensioned in length, and they must be precisely fitted during fitting into the compression packing. If required endless rings can also be supplied. If no information on the version, the fluid or temperature is given, B/B (see Operating parameters range table) is delivered as the standard version.
