该机组可配套提供JZ系列油扩散喷射泵真空机组（又称油增压泵机组）。该机组抽气能力大、粗抽时间短、设备维护简单、操作方便，是真空应用设备的理想配套设备。但该机组不适于排除对金属有腐蚀作用及对泵油产生化学反应的气体。现广泛地被太阳能制品企业所应用。
This unit comes with JK serial oil diffusion jet vacuum pump unit (also called oil booster unit).It has good capacity of gas extracting, with short rough extracting, easy to maintain and operating. It is ideal corollary equipment for vacuum application equipment.But this unit is not suitable for the gases which exclude corrosion towards metals and chemical reaction towards pump oil.Now it is widely applied by solar product enterprises.
1、比较SK系列单级水环真空泵而言，具有真空度高、在高真空区抽速大等特点。
2、相同抽速率下，轴功率明显高于2BV、2BE系列水环式真空泵。
3、因结构为双叶轮结构，制造、维修较为复杂，易损件较多。
2SK型水环式真空泵被广泛应用于食品、纺织、化工、医药和冶金工业及电子领域的真空蒸发、真空浓缩、真空回潮、真空浸渍、真空干燥及真空冶炼等。
2SK系列使用于吸入压力低于-0.08MPa的工况条件，2SK-P1系列使用于吸入压力低于-0.096MPa的工况条件。
该机组具有结构紧凑，操作灵活可靠，使用方便等特点，广泛应用于电子工业、冶金工业、化学工业、原子能工业以及宇航等科研技术领域。可为真空烧结炉，各种真空镀膜机以及真空电子束焊机、各类真空电炉、电子显微镜、各种电子射线、加速器、宇宙空间模拟容器所需之高真空环境均可用JK系列扩散泵真空机组来实现。
