The seal kits is a wear part for concrete pump, and the seal kits is made of composite polyurethane with abrasion resistance. The seal kits is widely used in hydraulic cylinders. It is necessary to pay attention to the oil cylinder daily inspection. Once the oil cylinder is found to have internal leakage or external leakage, replace the seal as soon as possible. If do not replace the seal kits, the hydraulic cylinder inner wall and the piston rod is easy to hurt.
The seal kits contains strong polar carbamate group and is insoluble in non-polar group, it has good oil resistance, toughness, aging resistance and adhesion.
Polyurethane seal kits is mainly used for oil cylinder, which is easy to install and can scrape the dust adhering to the piston rod. The seal kits have good physical and mechanical properties.
| Materials | Work Pressure | Working Temperature | Running Speed |
| Composite of PU | 69 Mpa | -60 to 130 ℃ | 0.5 m/s |
If the main oil cylinder is found to be seriously damaged, you should directly replace it with a new oil cylinder of the same concrete pump.
