Double acting piston seals

The function of Double Acting Piston Seal is to contain pressure on both sides of a piston without leakage and therefore allow maximum mechanical effort to be applied to moving the piston along the bore of a cylinder.

They can be driven either hydraulically or pneumatically, with appropriate seal designs for each system, and application.The seal is intended to prevent leakage across the piston and thus maximise the efficiency of system; pressure is applied from either direction, to drive the ram that the piston is fixed to both in and out or stop it in a controlled position.

Individual seal profile designs show specific behaviours and performance, which need to be in line with the application´s requirement.The material chosen will also influence the choice of seal profile. When determining the best seal design.

Double acting pneumatic piston seal - type NADUOP

Double acting pneumatic piston seal - type NADUOP Double acting pneumatic piston seal Type NADUOP of NBR, stands up to 10 bar and temperatures up to 110 C, at speeds to 1 m/s. The pneumatic seal NADUOP is suitable for pneumatic seals and acts as a double piston seal which is able to seal the dynamic pressure from both sides of the piston. The double acting piston seal NADIOP is with symetrical design, as its seal functions are equal in both moving directions. This Do..

Pneumatic piston seal AIRZET PK

Pneumatic piston seal AIRZET PK Piston seals AIRZET PK - labyrinth, double acting NBR seal ; Piston Seals, used in pneumatic cylinders, protect the piston head from leakage of fluids or gas. They are placed inside the cylinder head ensuring the maximum sealing. Piston seals are divided into 2 main categories: single-acting and double-acting, according to the direction of the pressure generated inside the cylinder. Pneumatic piston seal AIRZET PK can be pressurised o..

Pneumatic piston seal type KDN

Pneumatic piston seal type KDN Pneumatic piston seals type KDN is a compact double acting seal made of NBR. KDN type piston seal is suitable for pneumatic pistons and is oil resistant up to 110 C. The NBR pneumatic piston seals are known for increased chemical resistance. The base material for the pneumatic piston seals consists of NBR copolymer, carbon black reinforcement fillers, curing agents, molding process aids and specialty additives. The compact design o..

Pneumatic piston seal type TDUOP

Pneumatic piston seal type TDUOP This is a complete piston seal with steel base plate and vulcanised sealing lips with special pneumatic sealing edges. Double-acting piston seals of type TDUOP can be used in a wide range of cylinder applications and operating conditions. They can be pressurized from both sides, either exclusively from one side or simultaneously in the case of differential cylinders. The cross-section designs of Pneumatic piston seal type TDUOP are s..

Pneumatic piston seal type TR200

Pneumatic piston seal type TR200 Pneumatic piston seals type TR200is a compact double acting seal made of NBR. TR200 type piston seal is suitable for pneumatic pistons and is oil resistant up to 110 C. The NBR pneumatic piston seals are known for increased chemical resistance. The base material for the pneumatic piston seals consists of NBR copolymer, carbon black reinforcement fillers, curing agents, molding process aids and specialty additives. The compact des..

Pneumatic piston seal type FT

Piston seals FT has a rubber profile. This piston seal can be used also as hydraulic seal. FT is suitable for both rod and piston. It resists to oil bath at a constant temperature of 80 ° C. The maximum working pressure depends on coupling precision of mechanical parts. With a good coupling precision it can resist up to 100 bar in hydraulic application avoiding that the seal is subjected to pressure surges (water hammer). table { border-collapse: collapse; width: 1..

Pneumatic piston seal type MPS2

Piston seals type "MPS2": - Double acting seal PU. MPS2 type piston seal is suitable for pneumatic pistons. Its symmetrical design creates equal seal force across both seal lips. This gives the seal the capability to function as both a piston seal and rod seal or alternatively to seal dynamically on both the outside and inside diameters. This feature is often appreciated when reduced product inventories are desired. table { border-collapse: collapse; width: 100%;..
