Product Overview
BD-HYSJ Vertical Long Shaft Fire Pump is a vertical turbine-type fire pump designed to draw water from deep wells or underground reservoirs for fixed fire protection systems.
It ensures stable rated flow and head under fire-duty conditions where suction lift exceeds standard centrifugal pump limits.
It is applied in municipal fire stations, industrial plants, tank farms, and facilities requiring deep-water fire intake systems.
Model Designation

How to Select a Pump Model
- Confirm static water level and dynamic drawdown depth
- Determine required rated fire flow and head
- Calculate total shaft length according to well depth
- Verify motor power based on full-load fire duty
- Ensure compliance with local fire system standards
Engineering Notes
- Shaft alignment accuracy directly affects vibration level
- Submerged bowl installation depth must prevent vortex formation
- Intermediate bearing spacing impacts shaft stability
- Fire pump rated curve must match system hydraulic resistance
Compliance & Quality Assurance
- Factory hydraulic performance test at rated fire duty
- Shaft dynamic balance inspection
- Material traceability for pressure-containing components
- Optional third-party inspection before delivery
Safety Notice
- Do not operate without adequate submergence depth
- Ensure proper shaft alignment before commissioning
- Disconnect power supply before maintenance
- Avoid dry running under any condition
