HDB2 and HDB50 Metallic 2″ (50mm) AODD – Ball Valve Pump

The exclusive Sandpiper 2″ HDB2 Evolution Heavy-Duty Ball Pump is a mainstay in challenging customer applications, moving thin-highly viscous and small, solids-laden fluids.

The 2″ metallic pump provides excellent durability in demanding applications and is designed to withstand the most rugged and harsh ball valve environments.

The HDB2 is available in top- and down-porting options, which make installation easy and optimize performance on the pumped fluid. 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.

Description

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

Features:

  1. Top-port option: 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.
  2. Down-port option: 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.
  3. Heavy-duty plunger bushings and actuator pins: Designed to withstand severe applications
  4. Diaphragm wear pads: Installed between the diaphragm and outer diaphragm plate, providing a secondary wear surface that extends the life of the diaphragm
  5. Thicker, more robust wetted castings: Provide extended wear resistance
  6. Heavy-duty weighted check valve balls: Are 30-60% heavier than solid rubber check balls, allowing for more consistent chamber filling
  7. Intake/Discharge Pipe Size: 2 ” (50mm) NPT (F)
  8. Capacity: 0 to 511 litres/minute
  9. Air Distribution Valve: No-lube, no-stall design
  10. Solids Handling: Up to 9mm
