Ruichen Seal's rotary seals for cement slurry are made of high-performance engineering plastic toothed seal rings and O-shaped rubber rings. They are suitable for harsh working conditions such as plunger pumps, mud pumps, screw drills, drilling rigs, oil exploration equipment and concrete mixing plants. They are divided into two models: RC2061 and RC2062.
Both RC2061 and RC2062 are suitable for one-way sealing of hydraulic reciprocating and rotary motions. They have the characteristics of long life, low friction, good sealing, small structural space, and easy installation, use and maintenance. The special sealing lip and thickness optimization design have good sealing effect even in malignant media such as cement slurry. When used for sealing slurry media, we recommend grease lubrication between two (or more) seals.
Product features and applications:
Product features:
Long life: Combination of high-function engineering plastics and rubber, strong durability.
Low friction: Optimized design reduces running resistance and improves efficiency.
Excellent sealing: Special sealing lip design, suitable for malignant media such as cement slurry.
Compact structure: Small space design, easy installation and maintenance.
Applicable to harsh working conditions: Designed for media such as mud and cement slurry, with stable performance.
Application scenarios:
Oil exploration equipment such as plunger pumps, mud pumps, screw drills, drilling rigs, etc.
Construction machinery and equipment such as concrete mixing stations.
Other hydraulic reciprocating and rotary seals that require wear resistance and resistance to malignant media.
Technical advantages:
Special lip and thickness optimization design to adapt to extreme working conditions.
Easy installation, low maintenance cost and long service life.
Applicable to harsh environments with high wear and high pollution.
Usage suggestions:
When used for mud media, it is recommended to grease and lubricate between two (or more) seals to extend the life of the seal.
