SANDPIPER CLASS-LEADING, HIGH-FLOW HEAVY-DUTY BALL PUMP

The exclusive SANDPIPER 3" HDB3 and 4" HDB4 Evolution Heavy-Duty Ball Pumps are the best in class for moving thin-highly viscous and small, solids-laden fluids.

These pumps have the AODD pump industry’s highest maximum flow, with up to 300 gpm. They provide excellent suction lift capabilities and are designed to withstand the most rugged and harsh ball valve pumping applications.

All SANDPIPER heavy-duty ball pumps are ATEX-certified. The HDB3 and HDB4 are available in top- and down-ported options for optimized performance. These porting configurations solve critical problems, such as solids and abrasives settling out of the liquid chamber into the ball check area. They are designed to outlast standard pumps.

SANDPIPER Heavy-Duty Ball Pump Features

These pumps are enhanced with extended-wear packages and are your optimal solution for abrasive-slurry applications:

• Top-ported: For fluids containing floating solids, suspended solids or entrained gases. The discharge port is positioned above the center of the pump for easier evacuation and less build-up of solid material or gases.
• Down-ported: For fluids containing settling solids. The discharge port is positioned below the center of the pump so solids settle in the elbow and are discharged. This helps reduce wear on the diaphragms and associated components.

• Heavy-duty plunger bushings and actuator pins: Designed to withstand severe applications
• Diaphragm wear pads: Installed between the diaphragm and outer diaphragm plate, providing a secondary wear surface that extends the life of the diaphragm
• Thicker, more robust wetted castings: Provide extended wear resistance
• Heavy-duty weighted check valve balls: Are 30-60% heavier than solid rubber check balls, allowing for more consistent chamber filling

Performance Guarantees

• Diaphragm Connecting Rod Guarantee
• 5-Year Limited Product Warranty
• Anti-Stall Air Valve Guarantee
