The SANDPIPER HDB3 METALLIC 3" (80 MM) and HDB4 METALLIC 4" (100 MM) set a high standard for handling thin, highly viscous fluids and small solids. With industry-leading maximum flow rates up to 300 gpm, these pumps offer exceptional durability and suction capabilities for challenging environments, outperforming standard pumps in harsh ball valve applications.  

1/ Key features: 

• Top-port option: Suitable for fluids with floating or suspended solids and gases, minimizing material buildup and easing evacuation.  
• Down-Port option: Optimal for settling solids, directing discharge below the pump center to reduce diaphragm wear and extended pump life 
• Extended-Wear Components: Reinforced with robust bushings, weighted check valve balls, and wear-resistant diaphragm pads for longevity.  

2/ Application
