PGZ is specifically designed for hydraulic cylinder sealing in heavy machinery and metallurgical equipment. It offers exceptional performance characteristics:
✔
Strong pressure and corrosion resistance.
✔
Excellent thermal conductivity and anti-distortion mechanism.
✔
Low friction and elimination of creeping phenomena.
Working Conditions & Media
Compatible Media: General hydraulic oil, petroleum-based hydraulic oil, oil-in-water emulsion (HFA, HFB), water glycol (HFC), biodegradable hydraulic oil, air, and water.
Note: Phosphate ester-based hydraulic oil requires the use of FKM fluoroelastomer O-rings.
📝 Ordering Example
For a Bore size = 100mm, please specify: PGZ0100 or PGZ 100*80*10
💡 Frequently Asked Questions
What applications is the PGZ seal suitable for?
The PGZ seal is ideal for hydraulic cylinders used in heavy-duty machinery and metallurgical equipment where high pressure and reliability are required.
What materials are used in the construction of the PGZ seal?
The seal ring is made of filled Polytetrafluoroethylene (PTFE), and the O-ring is available in either Nitrile Rubber (NBR) or Fluorine Rubber (FKM) depending on your application needs.
What is the maximum pressure rating for this seal?
PGZ seals are designed to withstand high-pressure environments up to 60 Mpa.
Can these seals handle extreme temperatures?
Yes, the temperature range for these seals is wide, spanning from -60℃ to +280℃, making them suitable for extreme industrial environments.
Does the seal prevent "creeping" in hydraulic systems?
Yes, one of the key features of the PGZ seal is its low friction design which ensures smooth movement and eliminates creeping phenomena.
How long does shipping typically take?
Standard delivery time is between 7 to 15 working days, depending on the order quantity and specific requirements.
