Full service requires coupling this wet end with a compatible 5.5 kW (7.33 HP) electric motor. The mechanical framework allows vertical well configurations or horizontal cisterns.\u003c\/p\u003e\u003cp\u003eConstructed for long-term submersion, the pump end features a stainless steel outer sleeve. The internal floating stack contains 38 stages utilizing PC\/PPO + PS polymer components. This hydraulic design handles water with suspended sand up to 150 grams per cubic meter.\u003c\/p\u003e\u003cp\u003eWhen matched with a compatible 5.5 kW motor operating on 13.7 Amps current (415 V three-phase line), the coupled assembly yields a maximum head of 214.8 m. The pump end achieves a maximum flow of 183 L\/Min discharging through its Rp 2\" (50 mm) outlet. Output is verified by factory curves.\u003c\/p\u003e\u003cp\u003eLiquid temperature during operation must not exceed 35°C. This pump end is specified for submersion depths up to 150 meters with 4OS motor lines, and up to 300 meters with L4C motor lines. Horizontal use is possible for 4OS motors up to 2.2 kW and L4C motors up to 7.5 kW. The multi-stage design requires proper coupling with standard motors to maintain correct performance under standard system heads.\u003c\/p\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003eEquipped with 38 multi-stage floating impellers designed to minimize abrasive wear from sand particulates.\u003c\/li\u003e\n\u003cli\u003eThe external sleeve is fabricated from durable stainless steel to prevent rust and prolong operating life.\u003c\/li\u003e\n\u003cli\u003eIncludes a built-in stainless steel non-return valve in the discharge head to prevent damaging backflow.\u003c\/li\u003e\n\u003cli\u003eThe hexagonal shaft distributes mechanical torque evenly, eliminating vulnerable keyed connections.\u003c\/li\u003e\n\u003cli\u003eFeatures precision-cast stainless steel upper and lower brackets to maintain alignment with the motor.\u003c\/li\u003e\n\u003cli\u003eComplies fully with the Minimum Efficiency Index threshold of 0.40 under European ErP directives.\u003c\/li\u003e\n\u003cli\u003eDesigned to safely handle water temperatures up to 35°C in continuous underwater applications.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lowara","offers":[{"title":"Default Title","offer_id":51059135152375,"sku":"8GS55","price":3040.62,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-8gs55-stainless-steel-deep-well-4-inch-submersible-bore-pump-wet-end-only-with-floating-impeller_d0fce240-c1c4-4ca9-843f-2d56af4a2b84.png?v=1787571593","url":"https:\/\/foundationpumps.com.au\/products\/lowara-8gs55-stainless-steel-deep-well-4-inch-submersible-bore-pump-wet-end-only-with-floating-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
