Why Choose Us?
1.The NZJP series multi-stage Roots vacuum pump delivers a high ultimate vacuum by connecting multiple rotors in series, effectively combining the capabilities of several Roots pumps. With configurations ranging from 3 to 6 stages, it can achieve an ultimate vacuum as low as 1 Pa. These multi-stage Roots vacuum pumps are widely utilized in industries such as semiconductors, chemicals, and pharmaceuticals. They require a backing pump to create either Roots-screw or Roots-water ring vacuum units, which provide high vacuum levels and stable pumping speeds.
2.The NZJP series multi-stage Roots vacuum pump provides various seal options, including lip seals, mechanical seals, nitrogen seals, and magnetic seals, all ensuring high vacuum performance and stable system operation.
3.The NZJP series multi-stage Roots vacuum pump is designed to be compact, taking up minimal space.
4.The NZJP series multi-stage Roots vacuum pump is extremely efficient and energy-saving. Its multiple-stage compression allows for the performance of several Roots pumps connected in series, leading to substantial energy savings.
5.The NZJP series multi-stage Roots vacuum pump is designed with adaptive pressure control. Each stage of the pump is fitted with a bypass overflow valve that automatically adjusts to pressure variations during operation. This feature effectively prevents overload issues while the pump is in use.
6.The NZJP series multi-stage Roots vacuum pump has precise heat exchange capabilities. The front and rear oil tank covers feature a cooling water jacket structure, which enables accurate heat transfer for the pump chamber, gearbox, and bearing box.
7.There are various materials available to address corrosive conditions. The rotors and chambers can be coated with a nickel-phosphorus alloy or constructed from specialized materials like stainless steel, duplex stainless steel, titanium, and Hastelloy. These options effectively resolve the issue of medium corrosion.
