• Quench/Drain Ports: Equipped with quench and drain ports as standard, allowing for steam quench or water flush to clean the atmospheric side of the seal.
• Hydraulic Balance: Fully balanced design allows the seal to operate cooler and last longer, even in variable pressure conditions.
Key Features
• CURC / CURE Equivalent: A universal cartridge seal designed to replace the popular AES CURC (Single) or CURE (Single with Quench) models often found on standard electric motor pumps.
• Self-Aligning: The stationary face is flexibly mounted to accommodate the shaft misalignment common in close-coupled motor pumps.
• Standard Gland: Features a versatile gland plate with multiple bolt slots to fit ANSI, DIN, and vertical pump bolt circles.
