DIN 24960 Water Pump Seal Vulcan 7D Balanced Pusher Type
This single spring mechanical seal is engineered for leak-free performance in pump mechanical seal applications:
• Water Pump Seals: Municipal/industrial cooling systems
• Sewage Pump Seals: Wastewater treatment plants
• Oil Seals: Hydraulic systems & lubrication pumps
• Chemical Pumps: Moderate corrosion resistance
Combines corrosion-resistant materials with maintenance-friendly installation to extend mechanical seal life under moderate corrosion.
Product Description
• Vibration Control: VITON®/NBR/EPDM elastomers absorb axial movement for pump shaft sealing
• Precision Face Contact: Conical spring ensures constant pressure for rotating equipment seals
• Rapid Cartridge Installation: Enables in-pump seal replacement without disassembly
This single spring mechanical seal is ideal for pump mechanical seal replacement in light-to-medium industrial applications including cooling water, wastewater pumps, slurry pumps and hydraulic oil sealing (-30°C~200°C). Customizable single spring seal parts available.
*Complete mechanical seal cartridge includes DIN24960-compliant stationary seat.
