Industrial wiper

Overview
Scraper seals provide static and dynamic sealing for sliding shafts and hydraulic rods, preventing ingress of dust, particles and liquids while scraping contaminants from the rod or shaft.

Dimensions and operating parameters

• Recommended groove width: E + 1 mm (for DL).
• Maximum admissible pressure: 150 bar (DL); 30 bar (LIO, LEO).
• Admissible linear speed: up to 0.3 m/s depending on operating conditions.

Types available

• Type DL
• Type LIO
• Type LEO
• Type DRT
• Type DLI
• Type LIR
• Type LER
• Type DLE / DLES

Advantages

• Protects sliding shafts, rods and hydraulic cylinders from contaminants.
• Effective sealing in both static and dynamic conditions.
• High resistance to crushing and mechanical wear.
• Adaptable to a wide range of industrial machines and environments.

Specifications
The scraper seal designed by Paulstra Industry is suitable as a static or dynamic seal for sliding shafts. Properly installed, it prevents all types of impurities from entering machinery systems by scraping and evacuating debris from rods and shafts and avoiding particle infiltration into hydraulic cylinders.
