• Balanced and multispring design.
• Independent of rotation direction.
• Features a stuffing box gland shape.
• Includes flush connections for improved cooling.

• Shaft diameter (d1): 20 to 100 mm.
• Pressure (p): 25 kg/cm².
• Velocity (v): 16 m/s.
• Temperature (t): -15 to +200°C, dependent on secondary seal materials.
• Defined by the PV factor based on system and application characteristics.

This cartridge seal is economically designed to replace packing in pumps, featuring a stuffing box gland shape. The springs are protected from product exposure to prevent blockage in particle-laden fluids. Flush connections enhance the cooling of contact surfaces.
