HDB3 & HDB4 METALLIC 3" & 4"(80mm & 100mm) AODD - HEAVY-DUTY BALL VALVE PUMPS

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.

Features		Applications
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.		Abrasive Slurry Handling: Built for high-abrasion environments with extended-wear features. Solids-Laden Fluid Transfer: Specialized porting configurations address fluid and solid separation challenges Oil & Gas, Chemical, and Industrial processing: Reliable under extreme conditions and compliant with rigorous standards.
