The extended wear package of Sandpiper Heavy-Duty Ball Pumps includes heavier duty plunger bushings and actuator pins, diaphragm wear pads, and weighted check valve balls. This package can help to extend the life of the pump in demanding applications. The HDB3 and HDB4 are available in top- and down-ported options for optimized performance. The down-ported design also helps to prevent air entrainment, which can lead to cavitation and pump damage.

Features & Benefits

• 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: 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.
• Pumps thin to viscous and small solids-laden fluids
• Moves fluids a long distance
• Pumps fluids with abrasive or suspended solids
• Durable and long-lasting
• Easy to use and maintain
• Backed by a 1-year warranty
