water pump 18V DC - Wasserpumpe
thingiverse
I made this water pump for non time critical use to pump out a 1000 liter water tank. I use the 18V Maikta battery system for this. The additional necessary electronic parts have standard dimensions and are relatively cheap so there is some choice of what to build. I post my shopping list to it. The 1000 liter tank was empty in about 1.5 hours for me - but I had ZERO height to climb, as the outlet was at the bottom of the tank. Without this pump, draining took almost 14 hours. -------- Diese Wasserpumpe habe ich für den nicht zeitkritischen Einsatz zum Auspumpen eines 1000 Liter Wasserbehälters gemacht. Ich nutze dazu das 18V Maikta Akkusystem. Die zusätzlich notwendigen Elektronikteile haben Standardmaße und sind relativ günstig sodass es einige Auswahl gibt, was man verbauen will. Ich poste meine EInklaufsliste dazu. Der 1000 Liter Behälter war bei mir in ca. 1,5 Stunden leer - allerdings hatte ich NULL Höhe zu überwinden, da der Auslass am Boden des Behälters war. Ohne diese Pumpe dauerte das Auslassen fast 14 Stunden. -------- shopping list: 12V Submersible water pump: https://www.amazon.de/gp/product/B0B2WG75D4/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Step Down Wandler DC 8V~40V to 12V: https://www.amazon.de/gp/product/B082CCM8PJ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 PWM DC Motor Speed Controller: https://www.amazon.de/gp/product/B07ZPRM23X/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 Battery contact plate Makita: https://www.freytool.com/ersatzteile/ersatzakku-akkupack/644808-8-kontaktplatte.html Other: 2x Gardena tap connector 21 mm (1/2 inch) 4x M4 screw 16mm for the battery holder 4x M3 (Hexagon socket) screw 12mm for the pump cover 4x M3 (Hexagon socket) screw 20mm for the speed controller housing
