The Tsurumi LH25.5W provides a formidable solution for these intense environments, rapidly evacuating water to maintain safe and workable conditions. Its slim, cylindrical profile is specifically tailored for deployment in confined spaces like well casings.\u003c\/p\u003e\n\u003cp\u003eEngineered for high-capacity transfer, this model generates a maximum head of 62 m alongside a peak flow rate of 550 L\/Min. The three-phase 5.5 kW motor runs on a 415 V supply, pulling 10.5 Amps during standard operation. This finely tuned balance of electrical and hydraulic power ensures consistent fluid movement across significant vertical distances.\u003c\/p\u003e\n\u003cp\u003eThe hydraulic section utilizes dual closed impellers, expertly crafted to pass 6mm solids without compromising internal circulation. This design mitigates thrust loads and optimizes the movement of sand-laden water. Furthermore, the inclusion of pressure relief ports actively draws abrasive particles away from the sealing mechanisms, preserving the pump's core integrity.\u003c\/p\u003e\n\u003cp\u003eEncased in a rugged cast iron shell, the unit is fortified against the physical abuses of mining and construction sites. The 420 stainless steel shaft is supported by permanently lubricated C3 ball bearings, minimizing maintenance requirements. A galvanic zinc anode is also fitted to combat galvanic corrosion, significantly extending the hardware's functional life.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e Constructed from high-chromium cast iron to deliver exceptional abrasion resistance and stable high-head performance.\u003c\/li\u003e\n\u003cli\u003e Strategically positioned to prevent pumping pressure from acting on the shaft seal, enhancing overall reliability.\u003c\/li\u003e\n\u003cli\u003e Provides essential cathodic protection, actively sacrificing itself to prevent electrical corrosion of the main pump body.\u003c\/li\u003e\n\u003cli\u003e Adds a critical layer of defense against wear caused by the high internal pressures generated within the casing.\u003c\/li\u003e\n\u003cli\u003e Features an anti-wicking block that stops moisture from penetrating the motor housing via capillary action.\u003c\/li\u003e\n\u003cli\u003e Double-shielded and permanently lubricated to ensure smooth, continuous shaft rotation under heavy radial loads.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50934167044343,"sku":"LH25.5W","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-lh25-5w-cast-iron-deep-well-submersible-drainage-pump-for-mine-pits-with-dual-closed-impellers.png?v=1783937851","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-lh25-5w-cast-iron-deep-well-submersible-drainage-pump-for-mine-pits-with-dual-closed-impellers","provider":"Foundation Pumps","version":"1.0","type":"link"}
