Extreme High-Pressure Mastery: The Davey Bareshaft Twin-Stage Firefighter® (5250PV3)
When your setup demands massive head pressure to clear steep inclines, push water over long distances, or handle aggressive agricultural chemicals, the Davey Bareshaft 5250PV3 is the ultimate choice.
Engineered as a high-performance, twin-stage self-priming centrifugal pump head, it allows you to couple your preferred custom engine or electric motor (via direct-coupling or belt-drive).Outfitted with the V3 package, it features full chemical-resistant upgrades to tackle intensive farm spraying alongside heavy-duty firefighting.
Key Features & Benefits
Twin-Stage High-Pressure Design: Dual marine-grade impellers deliver extraordinary pressure capability, making it ideal for long-hose configurations and high-elevation water transfer.
V3 Chemical-Resistant Upgrades: Factory-equipped with Viton® seals, O-rings, gaskets, and caps, providing exceptional defense against agricultural fertilisers, pesticides, and herbicides.
Bareshaft Flexibility: Tailor-made to be long-coupled or belt-driven to virtually any custom engine or electric motor matching your unique specifications.
Marine-Grade Aluminium Build: The pump body, diffusers, and impellers are built from high-grade marine aluminium and finished with a robust interior and exterior epoxy coating for maximum corrosion resistance.
Patented Clamped & Thrust-Balanced Impeller: Engineered for a prolonged lifespan, minimized bearing load, and effortless cleaning or disassembly in the event of a blockage.
Floating Impeller Neck-rings: Front neck-rings optimise hydraulic efficiency, while back neckrings reduce wear and extend mechanical seal longevity.
Flexible 4-Way Discharge Port
