The impeller diameter of this water jet propeller is 80mm, with anti-recoil vector nozzle and reversing, which is an original design.\u003cbr\u003e\nEach component is based on the open water performance, propulsion performance, cavitation performance and pulsating pressure information to improve the design simulation optimization of the pump injection, and has a wide range of high efficiency areas and excellent anti-cavitation performance in the large range of the advance rate coefficient of 1.3-2.\u003cbr\u003e\n3. The impeller adopts the \"ternary design theory\" of large angle of attack and large chord length design. In addition to satisfying the hydrodynamic performance, the load distribution, cavitation performance and pulsating pressure distribution of the blade are optimized.\u003cbr\u003e\n \u003cbr\u003e\nThe basic configuration is as follows: 1. The 4-blade high-efficiency impeller with an impeller diameter of 80mm is used, and the high-strength synthetic material is 3D printed. (Or choose the CNC aluminum alloy impeller) to ensure the strength and dynamic balance effect.2. The shaft system is customized with 8mm stainless steel, the shaft sleeve is a 16mm outer diameter thickened stainless steel tube, and the two-end stainless steel high-speed flange bearing.3. The pump spray shell is fully 3D printed, and the thickened design (the thinnest wall thickness is greater than 4mm) ensures sufficient strength and durability. 4. The connection between the tail seat and the base adopts an embedded rubber o-ring, eliminating the need for silicone bonding.\u003cbr\u003e\nDue to the use of 3D printing, flaws are inevitable and do not affect the use. Perfectionists are advised not to purchase.\u003cdiv\u003e\u003cimg referrerpolicy=\"no-referrer\" src=\"https:\/\/img.alicdn.com\/imgextra\/i2\/20286916\/TB2_9hgdhYaK1RjSZFnXXa80pXa_!!20286916.jpg\"\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cimg referrerpolicy=\"no-referrer\" src=\"https:\/\/img.alicdn.com\/imgextra\/i3\/20286916\/TB2CHQ3c6TpK1RjSZKPXXa3UpXa_!!20286916.jpg\"\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cimg referrerpolicy=\"no-referrer\" src=\"https:\/\/img.alicdn.com\/imgextra\/i4\/20286916\/TB2oR.2cW6qK1RjSZFmXXX0PFXa_!!20286916.jpg\"\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cimg referrerpolicy=\"no-referrer\" src=\"https:\/\/img.alicdn.com\/imgextra\/i2\/20286916\/TB2n.c1cYvpK1RjSZPiXXbmwXXa_!!20286916.jpg\"\u003e\u003c\/div\u003e","brand":"VAJJEXRC","offers":[{"title":"With 3d printed nylon 4 leaf, impeller","offer_id":42308772266064,"sku":"4741689424964","price":322.0,"currency_code":"USD","in_stock":true},{"title":"With aluminum alloy cnc4 blade, impeller","offer_id":42308772298832,"sku":"4741689424965","price":388.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0080\/1918\/1635\/files\/663335bcbb8c6687cdab24f28c26ab07.jpg?v=1777039469","url":"https:\/\/www.vajjexrc.com\/en-ch\/products\/80mm-jet-pump-thruster-with-cnc-aluminum-impeller-steering-and-reversing-for-rc-boat","provider":"VAJJEXRC","version":"1.0","type":"link"}
