Factory & Manufacturing
Vacuum pump performance depends directly on component manufacturing accuracy, rotor balance, structural alignment, zero-defect sealing, and rigorous final performance validation.
Our manufacturing process covers every critical stage-from raw material preparation and CNC machining to dimensional inspection, dynamic balancing, precision assembly, and multi-point vacuum testing. By applying strict quality controls at each production phase, potential defects are eliminated long before shipment.
Processing, Inspection, and Testing Infrastructure
Our facility operates 92 sets of processing equipment, including 30 imported high-precision machines and a dedicated dry screw vacuum pump machining center with 32 Mazak CNC machining units.

Step-by-Step Manufacturing Process
Component Preparation
Raw materials and cast parts are inspected for structural integrity, tensile strength, and chemical composition before entering production.
Precision Machining
Pump housings, shafts, rotors, and end covers are processed using 5-axis and horizontal Mazak CNC machining centers to maintain tight mechanical clearances.
Dimensional Inspection (CMM)
Machined parts undergo Coordinate Measuring Machine (CMM) checks to verify geometric tolerances and surface finishes prior to assembly.
Dynamic Balancing
Continuously rotating parts (such as rotors and shafts) are balanced in a specialized dynamic balance laboratory to prevent operational vibration, bearing wear, and mechanical fatigue.
Precision Assembly
Housings, bearings, rotors, vanes, synchronization gears, and seals are aligned and integrated according to exact CAD specifications in dedicated assembly bays.
Operational Run-In Inspection
Assembled pumps undergo preliminary run-in checks to verify rotation smoothness, seal integrity, and lubrication circulation.
Vacuum Performance Testing
Completed pumps are mounted on dedicated testing rigs to measure ultimate vacuum levels, pumping speeds, pressure stability, and thermal distribution.
Final Inspection & Packaging
Every unit passes a multi-point quality check, anti-corrosion treatment, and export-grade protective packaging before dispatch.
Specialized Manufacturing Controls by Pump Type
Rotary Vane Vacuum Pumps
Rotary vane units rely on an eccentric rotor sliding within a precision-bored pumping chamber.
Critical Factors: Vane slot clearances, rotor eccentricity, vane edge contouring, and thermal expansion management.
Process Sequence: Component Preparation - CNC Machining - CMM Inspection - Sub-assembly - Operational Run-in - Vacuum Testing - Final Dispatch Inspection.
Roots Vacuum Pumps
Roots pumps utilize two synchronized, non-contact rotors turning inside a dual-lobe chamber.
Critical Factors: Rotor profile geometry, shaft alignment, gear synchronization, dynamic balance, and non-contact tip clearances.
