Parker ZW piston seal combination
ZW-type double-acting piston seal consists of a rubber sealing element, two retaining rings and two guide rings.
1. Advantages:
● guide and sealing functions are performed by the seal itself in a very small space to achieve.
● suitable for mineral oils, HFA, HFB and HFC fire resistant hydraulic oil (the maximum temperature of 60 ℃) use.
● seal easy to install.
● simple, short length, the overall piston installation.
● special geometry NBR sealing elements so that the installation does not distort in the groove.
2. Materials:
Rubber elements: Shore hardness high wear resistance of NBR compound NB078 80.
Collar: high strength and durable polyester elastomer (W5035).
Angle guide ring: even in the case of increasing the temperature of the thermoplastic material is also resistant to high pressure (W5301).
If the special requirements (pressure, temperature, speed, etc.), please consult our service department in order to recommend the right materials and structures.
3. Application:
Working pressure: ≤400bar
Operating temperature: -35 to + 100 ° CHFA, HFB and HFC fluid maximum temperature of 60 ° C
Surface speed: ≤0.5m / s
Such seals for industrial and mobile equipment in presses, actuating cylinder, the support cylinder and the work cylinder double acting piston.
4. Installation:
It must be removed to install the seal area of sharp edges and burrs. Install in the following order: "rubber seals - collar - guide ring." Should be taken to ensure that the position of the guide ring and check ring contact points (gap) in a staggered configuration.
