該系列羅茨泵原可作為增壓泵使用，但不能直接地把氣體排到大氣中去，其前級(jí)泵可用滑閥泵或旋片泵、水環(huán)泵、油環(huán)泵等真空泵。本系列羅茨泵的主要特點(diǎn)有：

● 極限真空度高，用雙級(jí)滑閥泵作前級(jí)泵時(shí)，極限真空可進(jìn)入10-5托。
● 本身配帶溢流閥起自動(dòng)保護(hù)作用。
● 泵腔內(nèi)無互相滑動(dòng)的零件，因此無需用油潤滑。
● 轉(zhuǎn)動(dòng)部件作過細(xì)心的平衡，因此連接平穩(wěn)、噪音低。
● 泵的傳動(dòng)采用可靠的消結(jié)構(gòu)，因此可在高壓差下長期工作。
● 在各種真空爐、真空鍍膜機(jī)、真空包裝、真空冶煉、真空干燥、真空浸漬、航空航天、高真空模擬試驗(yàn)、 太陽能電池以及其他真空作業(yè)上 廣泛地應(yīng)用。
● 尤其在金屬鎂和海綿鈦行業(yè)應(yīng)用更為廣泛。

The series ZJP Roots vacuum pump can be used as boosters combined with a backing pump such as a rotary piston or a rotary vane vacuum pump. Or a liquid ring vacuum pump. But they can not be used to exhaust gas directly to atmosphere.

The series ZJP Roots pumps are high in ultimate pressure （With a double stage rotary piston pump its backing pump. A roots pump can attain an ultimate pressure of 10-4hpa ）Their inherent overflow valve play auto-protective role. Lubrication is unnecessary as there is no contact between rotors，rotor and housing. The robust drive of the pump and operating parts balanced carefully permit that the pump be stable operated continuously under the condition of high pressure differential. The series ZJP roots pump also have a feature of lower noise. It widely used for vacuum furnace, vacuum coating, vacuum packing, vacuum metallurgical, vacuum drying, aviation aerospace、high vacuum imitation experiment、solar power energy battery and other vacuum work widely used.

It widely used for Titanium Sponge Magnesium metal.
