This high-capacity three-phase unit is designed to manage clean or grey water in site ditches and factory sumps where large volume water transfer is critical. The 316 stainless steel construction provides a stable foundation for industrial management, ensuring that property remains protected from water accumulation. The system is specifically optimized for high-demand site drainage while operating with the stability of a three-phase motor.\u003c\/p\u003e\n\u003cp\u003ePowered by a 2.2 kW motor on a 415v supply, this model delivers exceptional performance for high-volume drainage applications. It generates an impressive maximum flow rate of approximately 1100 L\/Min and reaches a maximum total head of 20 metres to satisfy the most demanding discharge tasks. The electrical configuration maintains a steady 4.5 Amps run current during service, ensuring energy-efficient industrial operation. This performance profile allows for the rapid evacuation of large pits through the 80mm discharge port once operational cycles commence to protect critical infrastructure.\u003c\/p\u003e\n\u003cp\u003eHydraulic efficiency is centered on a 316 stainless steel open impeller that facilitates the passage of soft solids in suspension without compromising flow velocity. This centrifugal design is engineered to resist blockages, allowing the pump to manage liquids containing up to ten percent soft solids while maintaining high volumetric throughput. By maintaining hydraulic balance, the unit reduces internal vibration and wear, which significantly extends the functional life of the rotating assembly in harsh industrial settings. The open impeller configuration ensures that site drainage remains uninterrupted even when debris is present.\u003c\/p\u003e\n\u003cp\u003eMechanical stability is achieved through a heavy-duty 316 stainless steel pump body and motor top paired with Viton elastomers for enhanced compatibility. Longevity is anchored by a double mechanical shaft seal in an oil bath featuring silicon carbide and ceramic surfaces for maximum wear resistance. An internal automatic resetting thermal overload prevents burnout during high-load operating conditions, while the 10-metre HO7RNF oil-resistant lead ensures a safe industrial connection. The architectural casting includes high-grade 316 stainless steel fasteners for lasting structural integrity in submerged service.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHigh capacity 1100 L\/Min flow rate ensures rapid removal of water from large industrial and site pits.\u003c\/li\u003e\n\u003cli\u003eThree phase 2.2 kW motor provides superior starting torque and stable hydraulic behavior for dewatering.\u003c\/li\u003e\n\u003cli\u003eComplete 316 stainless steel build of body and impeller for maximum corrosion resistance in grey water.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal in an oil bath with hard-faced silicon carbide and ceramic faces for long-term protection.\u003c\/li\u003e\n\u003cli\u003eViton O-rings and elastomers provide excellent resistance to aggressive liquids and chemical impurities in waste water.\u003c\/li\u003e\n\u003cli\u003eOpen centrifugal impeller design allows for the passage of soft solids up to 10mm without internal blockage.\u003c\/li\u003e\n\u003cli\u003e10 metre HO7RNF oil resistant power lead with bare wire ends for professional three-phase industrial deployment.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Davey","offers":[{"title":"Default Title","offer_id":50865510154487,"sku":"DT22\/SS","price":3945.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/davey-dt22ss-316-stainless-steel-high-volume-dewatering-pump-for-water-transfer-with-open-impeller.png?v=1781594993","url":"https:\/\/foundationpumps.com.au\/products\/davey-dt22-ss-316-stainless-steel-high-volume-dewatering-pump-for-water-transfer-with-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
