WATER JET PUMP PROPULSION UNIT 80MM

cults3d

My 80mm design water jet thruster for bigger rc boats, kayaks, jet surf, small boat.. Great design with big steering angle, low drag for maximum water flow, high or low angle of attack impeller (two options- stl for both included). It offers great water cooling system for motor and esc (you dont need additional water pump). Shaft seats on 3 bearings for better stability. With brass inserts which are inserted very easily using soldering iron. You can choose between normal difusor or steering difusor. Walls are 3mm thick and this makes it very robust design. Easy to print (hard parts with PLA and gaskets with flexible filament). All you need to assemble it is: -3x skateboard bearing (8mm ID, 22mm OD, 7mm thickness), -2x lip seal (same dimension as bearing), -13x-7mm M4 brass threaded insert, -8x M4 bolt, -2x m4 nut, -2x kniping screw, -2x brass hose barb fitting for water cooling- 10mm thread, -1x 250mm long shaft 8mm thick , -1x M8 nut 24mm thick which is inserted in 6 blade impeller while printing process. You can check demonstration video of this jet unit here (in this video i used only 6s battery) : https://www.youtube.com/watch?v=PgiL3OGt4yM Tips: 3 blade impeller- when its fully printed expand two holes with 4mm drill and make M5 thread with hand tap. Then put in M5 concave end bolt to each side. When using this impeller you need 250mm shaft with two 2.5mm deep holes. First hole is located 40mm from the end of the shaft and the other 73mm from the end. Holes are rotated 180° (each on one side- like on the impeller). Match the holes on impeller and on the shaft and tighten the concave bolts to lock impeller on place. 6 blade impeller- first calculate time for printing not completed impeller. This is the time you will hit pause button and stop printing complete impeller. In that time you have to insert M8 nut inside (it is tight fit. If its to tight, use soldering iron to heat the nut to press it in easily). When the nut is in, just continue printing. For this impeller you will need 250mm shaft with 70mm thread at one end. you simply tighten impeller on the shaft. If possible use reinforced PLA for making impellers. Bearings and lip seal- just press them inside (first bearing, then lip seal) Shaft- needs to be as straight as possible. Any vibration will cause bearings to heat. Its best if its made of inox. If you are interested in finished product you can get it on our official website. We offer much improved jet pumps of size 80mm and large 100mm version. Both offer much more power than this pump.
