Wanpela paiplain pam i yusim pawa bilong wanpela lektrik mota long pulim wara i go insait long bodi bilong pam long rot bilong tanim 'impeller', we bihain i save givim wara i go long ples we ol i laikim long rot bilong paiplain. Ol ditel wok prinsipol em i olsem:
1. Suction Phase:Taim mota i stat, 'impeller' i stat long tantanim. Win insait long 'impeller' i save muv, na dispela i save kamapim 'negative pressure', we i save pulim wara i kam long bodi bilong pam i go insait long bodi bilong pam.
2. Displacement Phase:Taim 'impeller' i tanim, wara i go aut long autlet bilong bodi bilong pam. Long dispela proses, spit na 'geometry' bilong 'impeller' i save senisim 'liquid flow rate' na presa bilong en.
3. Bodi bilong Pam na Paiplain:Wara i save ron long bodi bilong pam i go insait long paiplain na i save go long paiplain i go long ples we ol i laik putim. Ol samting bilong paiplain olsem 'diameter', longpela, na ol samting bilong en i save mekim wok bilong paiplain i kamap gut na wok gut.
Em i bikpela samting long luksave olsem ol paiplain pam i gat sampela wok kondisen na ol hevi, olsem ol hevi bilong het bilong pam, tempereja bilong wara, na ol samting bilong viskositi. Long ol aplikesen tru, em i gutpela long makim stretpela kain pam, ol samting, na ol samting bilong en long inapim ol wok bilong en.
