單級(jí)雙吸離心泵泵體是水平剖分的螺旋形蝸殼，兩個(gè)呈半螺旋形的吸液室與泵殼一起為中開(kāi)式結(jié)構(gòu)。泵軸水平放置，軸的兩側(cè)支撐在裝有軸承的軸承座內(nèi)，雙吸式葉輪置于泵軸中間。泵的吸入口及排出口分別布置在下半個(gè)泵殼的兩側(cè)，泵體和葉輪兩側(cè)都裝有密封環(huán)，軸封裝置為填料密封，現(xiàn)在也有改用機(jī)械密封的，對(duì)稱布置在泵體的兩側(cè)。在泵蓋上設(shè)有兩根水封管將壓力水引入填料函進(jìn)行水封、冷卻和潤(rùn)滑。軸向力可自動(dòng)平衡，不必設(shè)置軸向力平衡裝置。檢修泵時(shí)，不必拆動(dòng)與泵體相連接的管路。在相同的流量下，雙吸泵比單吸泵的抗汽蝕性能更好。
雙吸泵的吸入口和排出口均在泵軸心線下方，雙吸泵的葉輪相當(dāng)于兩個(gè)相同大小的單吸葉輪組合在一起工作，在和單級(jí)離心泵葉輪一樣大小直徑的情況下流量可以翻一倍。雙吸泵泵體就是有兩個(gè)吸水室，特別之處主要還是雙吸葉輪的進(jìn)水方向與單吸葉輪不一樣，雙吸葉輪的好處就是同樣轉(zhuǎn)速與流量的情況下，由于減小了進(jìn)水口的流速、雙吸泵很難出現(xiàn)汽蝕現(xiàn)象。
