SPGW Hydraulic seals – Piston seals – SPGW

Description

SPGW is for reciprocated hydraulic systems.Possessing excellent performance if applied at heavy load and double sealing under high pressure working conditions.Particularly suitable for long stroke,large range of fluids and high temperature circumstance.Applicable for bigger piston gap.Simple groove structure.

Material

Profile seal: PTFE with bronze -brown color
Back up ring: POM - black color
Pressure ring: NBR - black color
Technical Data:
Diameter range: 50-300
Working conditions
Pressure: ≤50 Mpa
Speed: ≤1.5m/s
Media: Hydraulic oils (Mineral oil-based) / Fire resistant hydraulic fluid / Water and other medium
Temperature: -30~+110℃

Advantages

- High sliding speed;
- Low friction,free of stick-slip;
- Simple groove design;
- Long service life;
- Very good sealing performance even with pressure peaks;
- High resistance to abrasion;
- Increase clearance possible.
Resistance in oil, abrasion, solvent, weather
Excellent heat resistance, chemical resistance, solvent resistance, fluorination resistance, vacuum resistance, oil resistance, aging resistance and other properties

Applications

Reciprocating hydraulic system. In the high-pressure conditions of the bi-directional piston seal reload occasion very well.
Particularly suitable for long stroke and a wider range off luids and high temperature applications, applicable to the larger piston clearance. Mainly used in heavy construction machinery or cylinder piston seal leakage has good control, anti-extrusion
resistance and loss of performance, such as: excavators, and other heavy-duty hydraulic cylinders.
