• Protective Sleeve: The cartridge sleeve protects the 20mm/22mm shaft from wear by the O-rings or set screws.
• Hydraulic Balance: Balanced face design allows it to handle pressure spikes better than standard unbalanced component seals in small booster systems.
Key Features
• Small Bore Cartridge: A fully assembled cartridge seal standardized for 20mm and 22mm shafts, bringing big-pump reliability to small utility pumps.
• Zero-Setting Installation: Eliminates the need to measure and set the working length on small shafts, where access is often difficult.
• Universal Gland: Features a slotted gland plate that fits a wide range of 2-bolt and 4-bolt pump housings.

Industry Solutions
Case Study
Machine Tool Coolant: Small coolant pumps on CNC machines were leaking due to chip damage. We installed this Carbon/SiC Cartridge. The pre-set assembly prevented installation errors, and the hard SiC seat resisted the fines.
Testimonials
We use the 22mm cartridge for our oil circulation skids. It installs in 5 minutes and we never have call-backs.

FAQs about Metal Bellows Seals for High Temperature Pumps
Q: Why is a cartridge better for small pumps?
A: Small pumps have tight clearances. Installing a spring and aligning faces by hand is fiddly and error-prone. A cartridge guarantees the spring compression and face cleanliness are perfect every time, removing human error.
