This 415v model is specifically tailored for industrial environments where a three-phase supply allows for consistent hydraulic behavior during heavy shredding cycles. By utilizing a high chromium steel shredding ring at the inlet, the assembly macerates textiles and organic solids into a slurry for disposal into pressure sewer mains. The heavy-duty cast iron body provides a rigid foundation for deep-pit operation.\u003c\/p\u003e\n\u003cp\u003eThis commercial unit achieves a maximum flow rate of 180 L\/Min and reaches a maximum total head of 22.5 metres. Operating with a 2.3 Amps full load current, the 1.2 kW three-phase motor delivers exceptional energy efficiency and torque for continuous industrial dewatering tasks. This performance profile ensures the rapid evacuation of waste water through the 1 1\/4\" BSP F outlet port, maintaining clear flow paths in demanding discharge networks. The high head capability is ideal for sites requiring significant elevation gain.\u003c\/p\u003e\n\u003cp\u003eHydraulic efficiency is centered on an open centrifugal cast iron impeller and a grinding mechanism designed for superior solids handling. This configuration allows the DT12G to manage grey and black water containing suspended soft solids without internal blockages or volumetric loss. By facilitating high fluid velocity through the pump casing, the design prevents the accumulation of sediment that could compromise performance. The centrifugal flow path reduces internal friction, protecting the rotating assembly from premature wear in aggressive liquids.\u003c\/p\u003e\n\u003cp\u003eStructural longevity is provided by a 304 stainless steel motor shell and shaft paired with nitrile rubber elastomers for chemical resistance. Motor protection is reinforced by a double mechanical shaft seal in an oil bath, featuring a hard-faced silicon carbide\/ceramic seal for maximum durability. For professional installation, the unit includes a 10-metre HO7RN-F lead and a seal sensor lead for connection to protection relays. The integrated handle and rubber-cushioned mounting feet allow for easy handling and stable positioning in deep industrial sumps.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThree-phase 1.2 kW 415v motor provides stable hydraulic pressure and high starting torque.\u003c\/li\u003e\n\u003cli\u003eHeavy-duty high chromium steel shredder ring macerates organic solids and textiles into a slurry.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal in an oil bath ensures long-term motor insulation and protection.\u003c\/li\u003e\n\u003cli\u003eOpen centrifugal impeller design prevents internal clogging and supports high-head discharge.\u003c\/li\u003e\n\u003cli\u003eCorrosive resistant 304 stainless steel motor shell and fasteners for superior structural integrity.\u003c\/li\u003e\n\u003cli\u003eIntegrated seal sensor leads allow for connection to a protection relay for real-time monitoring.\u003c\/li\u003e\n\u003cli\u003eHO7RN-F 10 metre oil-resistant power lead with bare wire ends for professional three-phase connection.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Davey","offers":[{"title":"Default Title","offer_id":50866545098999,"sku":"DT12G","price":1908.25,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/davey-dt12g-cast-iron-double-mechanical-seal-submersible-grinder-pump-for-septic-effluent-with-open-impeller.png?v=1781604303","url":"https:\/\/foundationpumps.com.au\/products\/davey-dt12g-cast-iron-double-mechanical-seal-submersible-grinder-pump-for-septic-effluent-with-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
