SP43 Self-Priming Pumps – 3″ / 500 GPM

DAE Pumps SP43 Self-Priming Pumps are multi-purpose centrifugal self-priming pumps with a 4-inch intake and a 3-inch discharge, that provides a flow rate of up to 500 GPM at 45 PSI. The powerful yet compact SP43 delivers sustained suction with high efficiency and non-clogging performance, resulting in lower energy and fuel costs, and unplanned downtime. The close-coupled centrifugal pump mounts to a diesel engine or electric motor for easy pump end or engine/motor changeover in the field. The DAE Pumps SP43 comes on standard skids or an optional portable self-priming pump trailer.

The high discharge pressure, dry-running, and portability of the DAE Pumps SP43 makes this self-priming pump a preferred choice for water, sewage, wastewater, and dewatering applications. The cast iron construction with a hard iron impeller makes this pump durable and reliable for all construction sites. The SP43 self-priming centrifugal pump is available today!

The DAE Pumps SP43 is part of the SP-Series Self-Priming Pumps, which offer a variety of sizes, flow rates, speeds, and more to match your needs.
