Overview
Aurora fire pump packing rings 23 are critical maintenance components for fire protection pumping systems utilizing Aurora split-case and vertical inline pump designs. These non-asbestos packing rings form a seal around the pump shaft, preventing unwanted leakage while allowing controlled water drainage for shaft lubrication. Maintaining proper packing condition is essential for fire system reliability and regulatory compliance.
Key Features
- Non-asbestos construction for safe, modern fire pump operation
- Ring size 23 specification for compatible Aurora fire pump models
- Package of 10 rings per unit—convenient for repacking operations or inventory
- Designed to maintain shaft lubrication with controlled drip rate (15-40 drips per minute per side)
- Drop-in replacement for routine fire pump maintenance cycles
