Vertical Turbine Fire Pumps

Discharge Head:
Directs water flow from the vertical column pipe into the system piping, while supporting both pump and motor assembly. The head is machined to accommodate gear drives or motors.

Stuffing Box:
Maintains shaft alignment and prevents leakage. Includes packing rings and sealing around the line shaft.

Line Shaft:
Made of stainless steel, precision machined and threaded for alignment. Sized for strength and long-term thrust loads.

Line Shaft Coupling:
Connects shafts with precision-ground steel bar couplings for reliable power transmission.

Spider:
Multi-rib support structure aligns shaft and stabilizes column pipes.

Spider Bearing:
PTFE water-lubricated bearings reduce friction and ensure smooth shaft rotation.

Column Pipe:
Connected using flanges and precision-machined for perfect fit and parallel alignment.

Impeller Shaft:
High-strength stainless steel shaft, polished for smooth operation and durability under high thrust conditions.

Bowl Bearing:
Made of PTFE, designed to complement the impeller shaft, offering extended life and low friction.

Impeller:
Dynamically balanced and enclosed to ensure smooth rotation. Attached with collets or keys for stability.

Pump Bowl Assembly:
Houses impellers and diffuser vanes, reducing radial loads and minimizing shaft deflection. Also includes bearing inserts for optimal alignment and lubrication.

Casing Bowl Wear Ring:
Renewable wear rings limit leakage and maintain efficiency between impeller and casing.

Suction Bell:
Supports the lower end of the pump and allows fluid to enter the impeller eye efficiently.

Strainer:
Stainless steel strainer keeps debris out of the pump while maintaining clear water entry flow.
