1、輸送液體平穩(wěn)、無脈動、無攪拌、振動小、噪音低。
2、有很強的自吸性能，多相混輸時，含氣率不高于80%，含沙量不高于500g/m3.
3、外置軸承結構，采用獨立潤滑，可以輸送各種非潤滑性介質。
4、采用同步齒輪驅動，二轉子之間不接觸，即使短時間空轉也無妨。
5、泵體帶有加熱套，可以輸送各種清潔或含有固體小顆粒的低粘度或高粘度介質（一般顆粒直徑小于0.12-0.2mm)
6、正確的選用材料，甚至可以輸送很多有腐蝕性的介質。
7、雙吸式結構，轉子上沒有軸向力。
8、軸端采用機械密封或波紋管機械密封，具有壽命長、泄漏少、適用范圍廣的特點。
2W.W密封型雙螺桿泵性能范圍
1、工作壓力4.0MPa
2、流量范圍 1～1000m3/h
3、溫度范圍-20～120℃
4、介質粘度 1～3000mm2/s，降低轉速可達到106mm2/s
介質粘度對雙螺桿泵性能影響較大，泵的名義排量是指在特定粘度條件下的排量，為保證泵正常下工作，在試驗不充分時，建議按下列粘度條件選擇轉速：
介質粘度cSt 轉速r/min
＜400 1500
400 ～1200 1000
1200～3600 750
對于粘度更高的介質，所應選用的轉速和驅動電機功率，請與制造廠聯(lián)系。
