Famfon najasa Ƙarancin girgiza da hayaniya, ƙarancin zafin jiki a cikin motar, kuma babu gurɓatawa ga muhalli

I. Bayanin Samfura
Famfon najasa nau'in famfo ne wanda ke haɗa famfon da injin kuma yana aiki a ƙarƙashin ruwa a lokaci guda. Idan aka kwatanta da famfon najasa na kwance ko a tsaye na yau da kullun, famfon najasa yana da ƙaramin tsari da ƙaramin yanki na bene. Yana da sauƙin shigarwa da kulawa. Manyan famfon najasa galibi suna da na'urar haɗa kai ta atomatik, wanda ke ba da damar shigarwa ta atomatik. Shigarwa da kulawa suna da matukar dacewa. Lokacin aiki mai ci gaba yana da tsawo. Saboda haɗin famfon da injin, shaft ɗin yana da gajere, abubuwan juyawa suna da sauƙi, don haka nauyin (radial) da bearing ke ɗauka ƙanƙanta ne, kuma tsawon lokacin sabis ɗin ya fi na famfon na yau da kullun tsayi. Babu lalacewar cavitation ko matsalolin shan ruwa da fitarwa. Aikin yana da sauƙi. Girgizar da hayaniya suna da ƙasa, hauhawar zafin motar yana da ƙasa, kuma babu gurɓatawa ga muhalli.

Ya dace da ɗaga najasa da ruwan shara da ke ɗauke da ƙazanta masu laushi, laka, da wasu girman barbashi na barbashi masu tauri.
III. Siffofin Samfura
Saboda haɗin famfo da injin, gajeren shaft da kuma sassa masu sauƙin juyawa, nauyin (radial) da bearing ɗin ke ɗauka a kan bearing ɗin bai yi yawa ba, kuma tsawon lokacin sabis ɗin ya fi na famfo na yau da kullun. Babu lalacewar cavitation ko matsalolin shan ruwa da fitarwa. Aikin yana da sauƙi. Girgizar da amo suna da ƙasa, ƙaruwar zafin motar yana da ƙasa, kuma babu gurɓataccen yanayi.
