The 250 mm side discharge design is intended for high-capacity flow through industrial piping systems in mining and civil engineering projects. This construction is focused on moving large quantities of water quickly to maintain site progress.\u003c\/p\u003e\u003cp\u003eThe pump uses a 75 kW 415v three-phase motor to deliver a maximum flow of up to 17500 L\/Min and a maximum head of up to 38 m. This high-volume focus is designed for site dewatering where water contains up to 15% dry matter. It provides a reliable solution for sites requiring high-capacity displacement of excavation runoff through its 250 mm discharge.\u003c\/p\u003e\u003cp\u003eThe hydraulic configuration features a spiral side discharge casing that optimizes flow and reduces hydraulic losses for 25 mm solids. This geometry is tuned for volume throughput rather than extreme head, which lowers internal friction and improves efficiency during large-scale transfer. The arrangement ensures that site debris is moved through the casing without settling.\u003c\/p\u003e\u003cp\u003eCritical protection includes an electrode-type leakage sensor in the oil chamber and seal pressure relief ports that protect the seal faces from high hydraulic force. A motor cooling jacket facilitates heat dissipation during fluctuating water levels. The unit is constructed with a cast iron body and utilizes a Star-Delta starting method for reliable industrial activation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHigh-volume 17500 L\/Min flow capacity is tuned for rapid dewatering in large-scale projects.\u003c\/li\u003e\n\u003cli\u003eElectrode-type leakage sensor in the oil chamber monitors seal wear to prevent internal damage.\u003c\/li\u003e\n\u003cli\u003eSpiral side discharge casing facilitates large-volume flow and the passage of solids up to 25 mm.\u003c\/li\u003e\n\u003cli\u003eMotor cooling jacket enables continuous operation in-air during fluctuating site water levels.\u003c\/li\u003e\n\u003cli\u003eSeal pressure relief ports protect the mechanical seal by reducing internal hydraulic pressure.\u003c\/li\u003e\n\u003cli\u003eHeavy-duty 4-pole motor delivers the mechanical force needed for continuous massive drainage.\u003c\/li\u003e\n\u003cli\u003eCast iron body and Class F insulation provide the durability required for mining and site environments.\u003c\/li\u003e\n\u003cli\u003eStar-Delta starting method ensures controlled electrical startup for the 75 kW industrial power system.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50929805918455,"sku":"GSZ2-75-4L","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-gsz2-75-4l-cast-iron-high-volume-drainage-pump-for-floodwater-drainage-with-closed-impeller.png?v=1783679954","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-gsz2-75-4l-cast-iron-high-volume-drainage-pump-for-floodwater-drainage-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
