راهکارهای آب‌بندی ماشین‌آلات ساختمانی

Earthmoving equipment sealing solutions

Excavators, bulldozers and loaders operate in dusty, abrasive work environments, where the hydraulic cylinders of the arm and bucket are constantly under heavy load and pressure.

For each of these cylinders, Kastas designs a complete arrangement of rod seal, piston seal, wiper and guide ring that resists dirt ingress and wear.

• High resistance to wear and dirt ingress
• Excellent sealing performance in heavy-duty conditions
• High extrusion resistance with a back-up ring
• Competitive cost and easy installation

Concrete pump sealing solutions

The boom cylinders and outrigger legs of concrete pumps must provide precise sealing and guidance at peak operating pressures for the long-term life of the equipment.

• Superior sealing performance under peak pressures
• High wear and extrusion resistance
• Excellent guidance and long-term service life
• Economical solution with easy installation

Telescopic dumper sealing solutions

The performance of the whole telescopic tipper depends on a single telescopic cylinder; if this one cylinder leaks or its guidance is not accurate, the whole machine fails.

For this cylinder, Kastas designs a dedicated telescopic sealing solution that maintains precise guidance and stable sealing along the full length of the cylinder.

• Dedicated, purpose-developed telescopic sealing solution
• Excellent guidance and sealing for whole-system performance
• Good cost and efficiency for sustained productivity

Hydraulic breaker sealing solutions

Hydraulic hammers, drills and rock breakers work with continuous, high-speed blows in an environment full of dust and rock particles; this combination of high frequency and environmental contamination wears the seal out sooner than usual.

For these conditions, Kastas designs seals with high resistance to impact and particle ingress, which preserve the part's life in continuous operation.

• Hammers
• Drills
• Rock breakers
