The side discharge spiral casing is built for large-bore fixed piping in permanent site drainage installations where high head performance is a primary requirement. This design is utilized where reliable movement of large-volume site water is critical to maintaining operational safety.\u003c\/p\u003e\u003cp\u003eWith a 75 kW 415v motor, the unit achieve a maximum head of up to 52 m and a peak flow of up to 12500 L\/Min through a 250 mm bore. It maintains discharge for site water with up to 15% dry matter within a pH range of 5 to 9. The 4-pole motor provides the mechanical torque required for high-capacity transfer over significant vertical distances.\u003c\/p\u003e\u003cp\u003eThe hydraulic design utilizes a spiral side discharge casing that streamlines the internal flow of solids up to 25 mm. This prevents site debris from accumulating within the casing and protects the housing from localized wear caused by high-velocity abrasive particles. The path is optimized to maintain high efficiency during large-volume discharge cycles.\u003c\/p\u003e\u003cp\u003eProtection features include an electrode-type leakage sensor in the oil chamber and seal pressure relief ports to protect the mechanical seal faces. A motor cooling jacket surrounding the housing enables heat dissipation during air-exposed operation. Construction includes a cast iron body and a Star-Delta starting method for industrial reliability.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOil chamber leakage sensor provide early warning of potential seal failure to protect the 75 kW motor.\u003c\/li\u003e\n\u003cli\u003eHigh-head hydraulic design delivers vertical lift up to 52 m for deep-site water management.\u003c\/li\u003e\n\u003cli\u003eSpiral side discharge casing optimizes volume flow and facilitates the passage of 25 mm solids.\u003c\/li\u003e\n\u003cli\u003eSeal pressure relief ports extend mechanical seal life by diverting high internal hydraulic stress.\u003c\/li\u003e\n\u003cli\u003eMotor cooling jacket enables continuous duty when the liquid level drops below the motor housing.\u003c\/li\u003e\n\u003cli\u003eHeavy-duty 4-pole motor delivers the torque required for massive industrial dewatering projects.\u003c\/li\u003e\n\u003cli\u003eRugged cast iron construction and Class F insulation support reliable operation in rough site sumps.\u003c\/li\u003e\n\u003cli\u003eStar-Delta starting method ensures controlled electrical startup for the high-power 75 kW motor.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50929805885687,"sku":"GSZ-75-4","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-gsz-75-4-cast-iron-high-head-drainage-pump-for-mine-dewatering-with-closed-impeller.png?v=1783679953","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-gsz-75-4-cast-iron-high-head-drainage-pump-for-mine-dewatering-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
