The side discharge configuration is intended for high-volume throughput in permanent installations requiring vertical lift over significant distances. This design is utilized where reliable site water control is necessary during deep excavations and high-elevation projects.\u003c\/p\u003e\u003cp\u003eEquipped with a 45 kW 415v motor, the unit delivers a maximum head of up to 41.3 m and a peak flow of up to 9240 L\/Min through a 200 mm discharge. It maintains performance for drainage water with up to 15% dry matter within a pH range of 5 to 9. The 4-pole motor provides the mechanical force required for massive volume transfer of abrasive site runoff.\u003c\/p\u003e\u003cp\u003eThe hydraulic design incorporates a spiral side discharge casing that reduces hydraulic losses and improves discharge efficiency for solids up to 25 mm. This path prevents sediment accumulation within the pump housing and lowers internal wear from abrasive debris. By streamlining internal flow, the design maintains hydraulic stability during demanding dewatering cycles.\u003c\/p\u003e\u003cp\u003eConstruction features include a heavy-duty cast iron body and a cooling jacket surrounding the motor for heat dissipation. Seal pressure relief ports protect the mechanical seal faces from high-pressure failure by diverting internal hydraulic force. The system utilizes a Star-Delta starting method and features high-grade Class F insulation for industrial duty.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHigh-power 45 kW motor provides the hydraulic lift and flow for large-volume site water management.\u003c\/li\u003e\n\u003cli\u003eSpiral side discharge casing streamlines the passage of solids while reducing internal housing wear.\u003c\/li\u003e\n\u003cli\u003eSeal pressure relief ports reduce the hydraulic pressure on the mechanical seal to extend service life.\u003c\/li\u003e\n\u003cli\u003eMotor cooling jacket enables continuous operation in-air by facilitating efficient heat transfer.\u003c\/li\u003e\n\u003cli\u003eRugged cast iron body and Class F insulation support durable service in abrasive site conditions.\u003c\/li\u003e\n\u003cli\u003eSuitable for solids handling up to 25 mm in site drainage water with a 15% dry matter content.\u003c\/li\u003e\n\u003cli\u003eStar-Delta starting method ensures controlled electrical startup for the 45 kW industrial motor.\u003c\/li\u003e\n\u003cli\u003eSide discharge arrangement is compatible with 200 mm fixed piping and guide rail fitting systems.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50929805820151,"sku":"GSZ845","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-gsz845-cast-iron-high-head-drainage-pump-for-civil-site-dewatering-with-closed-impeller.png?v=1783679950","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-gsz845-cast-iron-high-head-drainage-pump-for-civil-site-dewatering-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
