GW260 For APV PUMA Centrifugal Pump
This mechanical seal is designed to deliver reliable performance in a wide range of processing applications. It is particularly well-suited for:
• Food, dairy, and beverage processing systems
• Pharmaceutical and cosmetic manufacturing
• CIP (Clean-in-Place) and SIP (Steam-in-Place) applications
• Chemical and solvent transfer operations
Product Description
+
The GW 260 is a high-performance OEM mechanical seal specifically engineered for APV Puma series pumps. This seal features a proven single spring design that provides sufficient and consistent closing force, making it particularly adept at handling viscous fluids or media with mild abrasives. The precision-engineered sealing faces—carbon versus silicon carbide or ceramic—ensure extended service life in demanding applications involving thermal cycling and frequent cleaning cycles.
As a direct replacement for original equipment seals, the GW 260 provides identical dimensional fit and performance characteristics. The cartridge construction eliminates complex installation procedures, ensuring proper seal function from initial startup.
