• Metal Bellows Option: While ISC2 is often a pusher seal, we also offer a metal bellows version for pools using ozone or high-temperature heating, eliminating O-ring hang-up.
• Universal Fit: The gland plate slots allow it to fit a wide variety of large split-case or end-suction pumps found in aquatic centers.
Key Features
• ISC2 Standard: An aftermarket replacement for the Flowserve ISC2 (Industrial Standard Cartridge) series, tailored for large commercial aquatic and water filtration pumps.
• Stationary Spring Technology: Unlike rotating spring seals, the springs in the ISC2 design are stationary. This prevents spring distortion at high speeds and ensures better face tracking.
• Robust Water Service: Designed to handle high-flow commercial pool filtration systems where reliability is paramount and downtime must be minimized.

Case Study
Aquatic Center: A large water park's main filtration pump (100HP) blew a seal mid-season. OEM lead time was 4 weeks. We supplied an ISC2 equivalent stationary cartridge in 2 days. The stationary springs handled the pump vibration perfectly.
Testimonials
Overkill for a backyard pool, but perfect for our Olympic stadium pumps. The stationary design runs smoother than the old rotating seals.

FAQs about Metal Bellows Seals for High Temperature Pumps
Q: Why use a stationary seal?
A: In a stationary seal, the springs do not rotate with the shaft. This allows for higher speeds and better handling of shaft misalignment, which is common in large, high-flow water pumps.
