This pump end must be coupled with a 2.2 kW (2.93 HP) motor to become fully operational. Standard well installation is vertical, though horizontal deployment is permissible.\u003c\/p\u003e\u003cp\u003eAn outer sleeve of stainless steel protects the multi-stage hydraulic pathways. The assembly utilizes 12 floating impellers made of PC\/PPO + PS polymer components. The system handles suspended sand up to a maximum concentration of 150 grams per cubic meter.\u003c\/p\u003e\u003cp\u003ePairing this multi-stage wet end with a compatible 2.2 kW motor (rated at 14.4 Amps on a 240 V single-phase connection) enables a maximum head of 45.9 m. The pump end delivers a maximum flow of 367 L\/Min through its Rp 2\" (50 mm) outlet. Flow parameters follow manufacturer data.\u003c\/p\u003e\u003cp\u003eThe pump end is specified for continuous water temperatures up to a maximum of 35°C. Submergence limits are 150 meters with 4OS motors and up to 300 meters with L4C motor options. Horizontal installation is possible up to standard motor-rated power limits. 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 12 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":51059135578359,"sku":"16GS22","price":2325.35,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-16gs22-stainless-steel-deep-well-4-inch-submersible-bore-pump-wet-end-only-with-floating-impeller_d9c51558-171b-40f0-9049-27dd111792d7.png?v=1787571613","url":"https:\/\/foundationpumps.com.au\/products\/lowara-16gs22-stainless-steel-deep-well-4-inch-submersible-bore-pump-wet-end-only-with-floating-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
