Water Pumps
Buy Water Pumps
Water Pumps are one of the most frequently bought pieces of equipment on construction and civil sites — used for dewatering excavations, transferring water between storage points, supplying water for dust suppression, and supporting concrete operations. Wenbro stocks centrifugal and self-priming water pumps across a range of flow rates and engine sizes to match light through to high-volume pumping demands. For sites dealing with solids-laden or dirty water, our Trash and Waste Pumps are the more appropriate choice, and for below-ground and sump dewatering, Submersible Pumps are the purpose-built option. All units are maintained in-house by Wenbro’s service team.
Frequently Asked Questions
What are Water Pumps most commonly used for on construction sites?
Water Pumps are primarily used for dewatering flooded excavations and trenches, transferring water from storage tanks or bowsers, supplying water for compaction and dust suppression, and providing water for on-site concrete mixing. They’re one of the most versatile and frequently deployed pieces of site equipment.
What’s the difference between a self-priming and a non-self-priming Water Pump?
Self-priming pumps draw water from below the pump without manual priming — practical for dewatering where the pump sits above the water surface. Non-self-priming centrifugal pumps must be flooded before operation and are better suited to transfer applications with favourable suction conditions.
What flow rate do I need for site dewatering?
Required flow rate depends on the inflow rate into the excavation and the volume to be cleared in a given timeframe. Undersizing leads to the pump struggling to keep pace with inflow. Contact the Wenbro team on 087 073 7777 for flow rate guidance based on your site conditions and excavation dimensions.
Can Water Pumps handle water with light sediment or silt?
Standard centrifugal Water Pumps tolerate light silt and fine sediment but are not designed for significant solids content. Where water contains debris, silt, or solids, a Trash and Waste Pump is the appropriate choice to avoid impeller damage and premature wear.
Does Wenbro service Water Pumps after purchase?
Yes — Wenbro’s in-house team handles all Water Pump servicing and maintenance, including impeller inspection, seal replacement, and engine servicing. Call 087 073 7777 to arrange a service schedule.
