This Roots-screw vacuum unit offers several advantages over a single dry screw vacuum pump, including the ability to operate at lower ultimate pressures, greater energy efficiency, and higher pumping speeds. The oil-free design within the pump chamber ensures that no contaminants enter the evacuated system, resulting in a clean vacuum environment. Additionally, the absence of oil facilitates easier solvent recovery.
Furthermore, because this dry vacuum unit produces no waste oil or wastewater emissions, it helps your process comply with environmental regulations while still achieving high pumping speeds and deep vacuum levels.
Why Choose Us?
International Certifications
Boke has successfully obtained ISO9001, ISO14001, and ISO45001 certifications. Both the ZJP Roots vacuum pump and the VDP screw vacuum pump in the JZJD Roots-screw dry oil-free vacuum unit are also ATEX explosion-proof certified.
In-House Design and Manufacturing for Quality Assurance
Both the Roots and screw pumps are designed and manufactured in-house by Boke, allowing for complete control over quality. The components of these pumps are precision-machined by us. Each rotor undergoes G1-grade dynamic balancing, and we select bearings and seals from internationally recognized brands. Every pump is subjected to strict performance testing before assembly into the vacuum unit. After assembly, the unit undergoes tests for leakage, noise, vibration, and more. If you have specific testing precision requirements, please inform us in advance.
Custom Materials and Configurations Based on Your Process Conditions
Our JZJD dry, oil-free vacuum unit is versatile and can handle flammable, explosive, and condensable gases. Based on our experience, we can recommend the most suitable materials for your process, such as adding PEEK coating to flow parts or using stainless steel, duplex stainless steel, titanium alloys, and other specialized materials. We can also customize the unit with automation control systems to meet your needs and add components such as condensers, recovery tanks, filters, and vacuum buffer tanks as required.
