从China供应商批量进口2x Rotary Vane Vacuum Pump

The 2X rotary vane vacuum pump from Zibo Vacuum Equipment Plant Co., Ltd., headquartered in Zibo, Shandong Province, China, is an oil-sealed positive displacement pump designed for medium and rough vacuum applications. The pump operates on the sliding vane principle, where eccentrically mounted vanes slide within a cylindrical stator, trapping and compressing gas before exhausting it against atmospheric pressure. The 2X designation refers to a Chinese industry series standard for two-stage vane pumps, offering lower ultimate pressure than single-stage equivalents. Zibo Vacuum Equipment Plant Co., Ltd. positions this unit as both a standalone vacuum source and a backing pump for high-vacuum systems including Roots blowers and diffusion pumps.

Construction typically comprises a cast iron or aluminium alloy stator housing, carbon steel or composite fibre rotor, and spring-loaded or centrifugally actuated vanes of phenolic resin or carbon graphite composition. The pump requires mineral-based or synthetic vacuum oil for sealing, lubrication, and heat removal, with oil capacity and viscosity grade varying by frame size. Operating noise levels for this series are generally in the 65-75 dB(A) range at ultimate pressure, though actual sound pressure levels depend on motor speed, mounting, and acoustic environment. The compact footprint referenced in the source suggests frame sizes compatible with benchtop or mobile equipment installations, with motor power typically from 0.37 kW to 4 kW across the 2X series range.

Primary applications span pharmaceutical freeze-drying, food vacuum packaging, vacuum metallurgy, lamp and tube evacuation, and as forepumps for scientific instrumentation. Buyers include equipment OEMs, process engineering contractors, and maintenance departments in manufacturing facilities. The supplier indicates ISO and SGS certifications; buyers should request current certificate scope and validity dates. Trade terms including letter of credit and telegraphic transfer are mentioned, but specific advance percentages, usance periods, and currency should be negotiated directly. The pump ships from Shandong; confirm packaging for sea or air freight, and whether the supplier performs factory acceptance testing before dispatch.

Zibo Vacuum Equipment Plant Co., Ltd. is located at No.160 Shuangshan Street, Zibo 255200, Shandong Province, eastern China. The supplier carries an imported tier classification alongside harbour trust tier status on this marketplace. The recorded response rate is 0.00 percent with zero average response hours, indicating no recent buyer interaction data is visible. Importers should prepare for potentially delayed communication and plan sourcing timelines accordingly, establishing direct contact channels early in the procurement process.

The company manufactures rotary vane vacuum pumps and positions the 2X series for industrial and scientific applications. No founding year, employee count, annual production capacity, revenue figures, or named domestic or international clients appear in the source profile. The listing references ISO and SGS certifications without specifying standards, scopes, or accreditation dates. Buyers should request the supplier's business licence, factory audit reports, and current certification documentation before committing to volume orders. Verification of the Shandong facility's actual production capability versus trading-only activity is advisable for first-time importers.
