HDB2 and HDB50 Metallic 2" (50 mm) AODD – Heavy-Duty Ball Valve Pump

Stands out for its capability to move both thin and highly viscous fluids, including those laden with small solids, under extreme conditions. Available in top- and down-poting configurations, this robust pump delivers exceptional durability and versatility across challenging environments, effectively handling abrasive slurries and solid-laden fluids.

HDB2 And HDB50 Features		Applications
Top-port option: Ideal for fluids with floating solids, suspended particles, or entrained gases, ensuring smooth discharge flow and reducing build up. Down-Port option: Optimized for setting solids, with discharge below the center to allow solids to settle in the elbow, minimizing diaphragm wear. Extended-Wear enhancements: Engineered for durability in abrasive environments, featuring thicker wetted castings and wear-resistant components for long-term reliability.		Abrasive and Solid-Laden Fluids: With wear pads and thickened castings, ideal for severe, high-abrasion environments. Gas-Entertained or Settling Solid Fluids: Tailored porting options ensure performance efficiency and durability. Industrial Chemical Processing: Designed to manage a wide range of chemical types with material compatibility options.
