The Davey D15A manages these environmental demands by providing high-capacity fluid removal of clean or slightly dirty grey water of neutral pH containing up to ten percent soft solids. This submersible unit utilizes a heavy-duty cast iron pump body to provide a stable foundation while operating in garages or pits prone to flooding during heavy rainfall events. The system is specifically engineered for intermittent dewatering tasks where consistent water removal is critical for maintenance.\u003c\/p\u003e\n\u003cp\u003ePowered by a 0.15 kW single-phase motor, this model delivers reliable performance for low-head drainage applications on a standard 240V supply. It generates a maximum flow rate of approximately 150 L\/min and reaches a maximum total head of approximately 7 metres to satisfy household discharge requirements. The electrical configuration maintains a steady 1.5 A running current during service cycles, ensuring energy-efficient operation at a synchronous speed of 2850 rpm. This performance profile allows for the rapid evacuation of sumps once the integrated preset-length float switch activates the pumping cycle.\u003c\/p\u003e\n\u003cp\u003eHydraulic performance is centred on a polycarbonate open centrifugal impeller engineered to handle liquids containing soft solids in suspension without internal clogging. This design maintains high fluid velocity through the pump casing, preventing the accumulation of sediment that could otherwise compromise volumetric efficiency. By utilizing a centrifugal flow path, the unit minimizes internal friction and vibration, extending the operational life of the rotating assembly during prolonged use. The impeller is optimized for liquids containing environmental debris commonly found in domestic sumps.\u003c\/p\u003e\n\u003cp\u003eMechanical stability is achieved through a heavy-duty cast iron pump body and polycarbonate motor top, paired with a corrosion-resistant 304 stainless steel motor shell and strainer. The motor is protected by a single mechanical shaft seal combined with a sand slinger lip seal to prevent moisture and abrasive particles from entering the electrical chamber. An internal automatic-resetting thermal overload prevents burnout during high-load operating conditions, while the 10-metre HO7RNF oil-resistant lead ensures a safe power connection. The robust construction also includes high-grade 304 stainless steel fasteners and an integrated handle for long-term structural integrity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePolycarbonate open centrifugal impeller design allows the efficient passage of small soft solids in suspension.\u003c\/li\u003e\n\u003cli\u003eHeavy-duty cast iron pump body provides a rigid and durable foundation for sub-surface operation.\u003c\/li\u003e\n\u003cli\u003eCorrosion-resistant 304 stainless steel motor shell and strainer ensure long-lasting durability.\u003c\/li\u003e\n\u003cli\u003eSingle mechanical shaft seal combined with a sand slinger lip seal provides essential motor protection.\u003c\/li\u003e\n\u003cli\u003eAutomatic-resetting thermal overload prevents motor damage during high-load operating conditions.\u003c\/li\u003e\n\u003cli\u003eHO7RNF oil-resistant 10-metre power lead includes a 3-pin plug for rapid and safe deployment.\u003c\/li\u003e\n\u003cli\u003ePreset-length float switch enables fully automatic operation for unattended drainage and sump control.\u003c\/li\u003e\n\u003cli\u003eIntegrated mounting base ensures firm and stable positioning during installation.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Davey","offers":[{"title":"Default Title","offer_id":50865506681079,"sku":"D15A","price":460.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/davey-d15a-cast-iron-automatic-submersible-pump-for-sump-emptying-with-open-impeller.png?v=1781594968","url":"https:\/\/foundationpumps.com.au\/products\/davey-d15a-cast-iron-automatic-submersible-pump-for-sump-emptying-with-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
