The Top 10 Vacuum Pump Manufacturers in China (Update 2026)
China has a large vacuum equipment manufacturing base, but choosing the right supplier requires more than comparing pump prices.
A chemical plant looking for an oil-free dry screw vacuum pump has very different requirements from a paper mill sourcing a large liquid ring pump or a vacuum furnace project that needs a Roots booster system. Pump technology, operating pressure, gas composition, corrosion resistance, testing capability and system engineering are often more important than the manufacturer’s size alone.
This guide introduces 10 China-based vacuum pump manufacturers with publicly available vacuum pump product lines and industrial manufacturing capabilities. It is intended as a sourcing reference rather than a market-share ranking.
For buyers, the most useful question is not simply “Who is the biggest vacuum pump manufacturer in China?” but:
Which manufacturer has the right pump technology and engineering capability for my operating conditions?

How We Selected These Vacuum Pump Manufacturers
The companies in this guide were selected based on publicly available evidence that they manufacture or supply dedicated vacuum pump equipment rather than general-purpose water pumps or unrelated machinery.
The review considered several factors: whether the company publishes a recognizable vacuum pump product range, whether it covers industrial rather than only small laboratory equipment, whether vacuum systems or engineered units are available, and whether technical or manufacturing information is publicly accessible.
The list is not ranked by revenue, market share or export volume, because comparable audited data is not publicly available for all manufacturers.
For procurement purposes, this approach is more useful than presenting an unsupported “largest manufacturer” ranking.
10 Vacuum Pump Manufacturers in China
1. Vacculex
Vacculex is a China-based industrial vacuum pump manufacturer focused on dry screw vacuum pumps, Roots vacuum pumps, liquid ring vacuum pumps and complete vacuum systems.
Its published screw vacuum pump range covers approximately 110–2,700 m³/h, while its Roots pump portfolio extends to substantially higher pumping capacities. Vacculex also supplies Roots + screw and Roots + liquid ring vacuum systems for applications that require a combination of deeper vacuum and higher pumping speed.
A key strength is its focus on process industries rather than only general-purpose vacuum. Typical applications include chemical processing, pharmaceuticals, food and beverage, energy and other processes involving complex or condensable gases.
Vacculex states that its pumps undergo dynamic-balance, running and pressure testing before delivery. This type of published factory-testing procedure is worth asking any supplier about when evaluating industrial vacuum equipment.
Best fit: Buyers seeking dry screw, Roots booster or liquid ring technology for chemical and industrial process applications, especially where a complete engineered system may be required.
Buyer note: Provide gas composition and process conditions early. A dry screw pump for clean solvent recovery and a Roots + liquid ring system for wet gas service should not be selected using the same criteria.
Shandong Kaien Vacuum Technology manufactures a broad range of vacuum equipment including dry screw, Roots, claw, rotary vane and water-ring vacuum pumps together with complete vacuum units.
Its published applications include vacuum drying, impregnation, metallurgy, coating, evaporation, concentration and oil-and-gas recovery. The company also states that it provides OEM customization and system integration.
The broad product portfolio can be useful for customers who want to compare several vacuum technologies from one supplier instead of starting with a predetermined pump type.
Best fit: General industrial users that want multiple pump technologies and customized vacuum units from one supplier.
Buyer note: Because the product range is broad, request application-specific performance curves and confirm which product series are produced directly at the manufacturer’s own facility.
Shandong Boke Vacuum Technology focuses heavily on dry screw, Roots and liquid ring vacuum technology.
Its published product range includes VDP variable-pitch dry screw pumps, ZJP Roots pumps and multiple 2BV, 2BE and two-stage liquid ring pump series. Boke states that it operates a 20,000 m² workshop and has dedicated engineering personnel and vacuum pump patents.
The company also provides Roots + screw and Roots + liquid ring vacuum systems, making it relevant to projects where a standalone pump is not sufficient.
Best fit: Chemical, pharmaceutical and petrochemical buyers comparing dry screw and liquid ring technologies.
Buyer note: Ask the supplier to size the system around the actual operating pressure and gas load rather than selecting only from nominal pumping capacity.
Shanghai EVP Vacuum Technology offers one of the broader publicly listed vacuum portfolios among Chinese suppliers.
Its range includes liquid ring, rotary vane, Roots, piston, dry scroll, dry screw, claw, diffusion and turbomolecular vacuum equipment as well as complete systems. EVP lists applications ranging from chemical and oil-and-gas processing to food, pharmaceutical, vacuum furnace and laboratory use.
This breadth may be useful for projects where several different vacuum levels or technologies are being evaluated.
Best fit: Buyers comparing multiple vacuum technologies, including both industrial process and higher-vacuum equipment.
Buyer note: Define the required vacuum regime carefully. A turbomolecular or diffusion pump project involves very different design considerations from an industrial liquid ring or screw vacuum system.
Anhui Foryou Vacuum Technology publishes product lines covering liquid ring, water ring, dry screw and Roots vacuum pumps together with vacuum systems.
The company states that it operates production bases and provides customized systems for chemical processing, pharmaceuticals, new energy and plastics. Its public supplier information also lists ISO 9001, ISO 14001 and ISO 45001 management-system certifications.
Best fit: Buyers looking for liquid ring, screw or Roots vacuum equipment for process-industry applications.
Buyer note: When evaluating customized equipment, request a clear system scope covering pumps, separator, condenser, controls, piping and utilities rather than comparing only the pump price.
Guangdong Wordfik Vacuum Technology publishes a wide product portfolio including dry and oil-lubricated rotary vane pumps, scroll pumps, dry screw pumps, claw pumps, Roots boosters and liquid ring pumps.
Its stated application markets include electronics, packaging, printing, food, plastics, pharmaceutical equipment, laboratories, woodworking and other industrial machinery.
This makes Wordfik relatively broad in terms of smaller and medium industrial vacuum technologies.
Best fit: Equipment builders, OEM users and customers comparing rotary vane, scroll, claw and screw vacuum technologies.
Buyer note: Match the pump series to the duty cycle and process gas. A pump suitable for a CNC machine or packaging line may not be appropriate for corrosive solvent or continuous chemical processing.
Development Vacuum Equipment, based in Zhejiang, lists rotary piston, Roots, dry screw, water-ring and rotary vane vacuum pumps as well as vacuum systems.
Published application areas include metallurgy, vacuum coating, heat treatment, pharmaceutical processing, transformer drying and other industrial vacuum processes.
The inclusion of rotary piston and Roots equipment makes DVE relevant to users working with traditional industrial vacuum systems as well as newer dry-pump configurations.
Best fit: Heat-treatment, transformer, metallurgy and general industrial vacuum projects.
Buyer note: Ask how the supplier configures booster-to-backing-pump ratios if a Roots system is proposed. The pumps should be sized as one system rather than selected independently.
Souz Vacuum, operated by Taizhou Shouzhen Machinery, lists Roots, liquid ring, dry and other industrial vacuum pumps together with complete vacuum systems.

Looking for a Vacuum Pump Manufacturer in China?
Selecting a supplier becomes much easier when the operating conditions are clear.
Send Vacculex your required inlet pressure, pumping speed, gas composition, gas temperature and application. The engineering team can evaluate whether your process is better suited to a dry screw pump, Roots booster, liquid ring pump or complete vacuum system.
How to Choose a Vacuum Pump Manufacturer in China
A supplier comparison should start with the process rather than the quotation.
Two manufacturers may both offer a “500 m³/h vacuum pump,” but the pumps can behave very differently when operating pressure, gas composition, temperature and condensable vapor load change.
Match the Manufacturer to the Pump Technology
The first question is whether the supplier has real experience with the vacuum technology your process requires.
A Dry Screw Vacuum Pump is often considered where an oil-free compression chamber, solvent handling or process cleanliness is important. Chemical, pharmaceutical and solvent-recovery projects frequently fall into this category.
A Roots Vacuum Pump is normally used as a mechanical booster with an appropriate backing pump when higher pumping capacity is required within a suitable pressure range.
A Liquid Ring Vacuum Pump is commonly selected when the process contains moisture, condensable vapor or wet gas. Performance depends strongly on seal-liquid temperature and system configuration.
Do not assume that a manufacturer offering all three technologies has equal engineering depth in every one. Ask for relevant application references and performance data.
Check Performance at Your Actual Operating Point
Ultimate vacuum is not enough to select an industrial vacuum pump.
A pump may have an impressive minimum pressure on a catalog page but deliver insufficient pumping capacity at the pressure where your plant actually operates.
Before requesting a quotation, provide the manufacturer with the required inlet pressure and pumping speed together with gas composition, temperature, condensable-vapor load and operating cycle.
Ask for the performance curve at or close to those conditions.
For liquid ring pumps, seal-liquid temperature should be included. For dry screw pumps, chemical compatibility, condensation risk and gas temperature are particularly important. For Roots systems, both the booster and backing-pump curves must be considered.
Verify Manufacturing and Testing Capability
A serious industrial vacuum pump supplier should be able to explain how the pump is manufactured and tested.
Ask how the manufacturer checks rotor or impeller balance, running performance, leakage or pressure integrity, vibration and final assembly.
Vacculex, for example, states that its vacuum pumps are subjected to dynamic-balance, running and pressure testing before delivery.
The purpose is not to look for one universal testing procedure. Different pump technologies require different tests. The important point is whether the supplier can provide a defined quality-control process rather than simply claiming that the pump is “high quality.”
Check Material and Process Compatibility
Pump material matters when the gas stream contains solvents, acids, corrosive compounds, polymers or particles.
A standard cast-iron pump may be sufficient for clean air but inappropriate for an aggressive chemical process.
Ask the supplier about:
- wetted materials;
- coatings;
- seals;
- purge arrangements;
- cooling;
- temperature limits;
- and process cleaning.
The manufacturer should understand what happens inside the pump under your gas conditions, not only supply a model based on flow rate.
Evaluate Spare Parts and Technical Support
Industrial vacuum pumps are long-term assets.
Before placing an order, confirm which wear parts are stocked, how quickly mechanical seals or bearings can be supplied and whether the supplier provides exploded drawings, manuals and maintenance guidance.
For large export projects, ask how troubleshooting will be handled if the pump is installed thousands of kilometers from the factory.
The lowest purchase price loses its advantage quickly if a small spare part creates weeks of downtime.
Decide Whether You Need a Pump or a Complete Vacuum System
Many industrial users do not actually need a standalone pump.
A complete installation may require:
- a backing pump;
- Roots booster;
- gas-liquid separator;
- condenser;
- heat exchanger;
- seal-liquid circulation;
- valves;
- instrumentation;
- piping;
- and control logic.
For these projects, evaluate the manufacturer as a vacuum system supplier, not just as a pump factory.
Vacculex provides application-specific Roots + screw, Roots + liquid ring and other [customized vacuum system] configurations for different operating pressures and gas conditions.
Chinese Vacuum Pump Manufacturer vs Global Vacuum Brand
Buying from China is not automatically better or worse than buying from an established international brand.
The decision depends on project priorities.
| Factor | China-Based Manufacturer | Established Global Brand |
| Purchase cost | Often competitive | Often higher |
| Customization | Can be flexible | Depends on manufacturer |
| OEM/private label | Often available | Less common |
| Global service network | Varies significantly | Usually more established |
| Local inventory | Depends on distributor | Often stronger in major markets |
| Engineering documentation | Varies by supplier | Usually standardized |
| Best fit | Custom and cost-sensitive industrial projects | Projects prioritizing global service infrastructure |
A good Chinese manufacturer can be a strong option when technical requirements are clearly defined and the supplier has the right engineering experience.
The important point is to evaluate the individual manufacturer rather than assuming that all Chinese suppliers have the same capability.
Which Vacuum Pump Type Fits Your Application?
Choosing the right supplier becomes easier once the pump technology is clear.
Dry Screw Vacuum Pumps
Dry screw pumps use rotating screw rotors to transport and compress gas without oil or water as a working fluid in the compression chamber.
They are often considered for chemical processing, pharmaceutical production, solvent recovery and processes where contamination from pump fluids is undesirable.
Key selection parameters include gas composition, inlet temperature, condensation risk, corrosiveness and required operating pressure.
Roots Vacuum Pumps
Roots pumps provide high pumping capacity but normally require a suitable backing pump.
They are widely used as boosters in industrial systems where a standalone backing pump cannot provide the required pumping speed at lower pressures.
The important selection question is therefore not simply the Roots pump size, but how the booster interacts with the backing pump.
Liquid Ring Vacuum Pumps
Liquid ring pumps use a circulating operating liquid to create the compression chambers.
They are particularly useful for wet gases, condensable vapor and many process applications where a dry pump may require more complex vapor management.
However, the achievable vacuum and pumping capacity depend on the seal-liquid temperature and operating conditions.
Customized Vacuum Systems
A customized system may combine multiple vacuum technologies and auxiliary equipment.
Typical examples include:
Roots + Dry Screw Vacuum System
and:
Roots + Liquid Ring Vacuum System
This approach is often appropriate for large chemical, pharmaceutical, evaporation, distillation, drying and other industrial processes.
Frequently Asked Questions
Who Are the Main Vacuum Pump Manufacturers in China?
China has many vacuum pump manufacturers serving different markets. Manufacturers such as Vacculex, Shandong Kaien, Shandong Boke, EVP, Foryou and others offer industrial pump technologies including dry screw, Roots, liquid ring, rotary vane and complete vacuum systems.
There is no single manufacturer that is best for every application. The correct choice depends on the required pump technology and process conditions.
How Do I Choose a Reliable Vacuum Pump Manufacturer in China?
Start by checking whether the manufacturer specializes in the pump type your process requires.
Then evaluate performance data, application experience, manufacturing and testing procedures, materials, spare parts, technical documentation and system-engineering capability.
For industrial processes, a technically correct pump selection is more important than choosing the lowest initial price.
What Types of Vacuum Pumps Are Manufactured in China?
Chinese manufacturers produce most major industrial vacuum pump technologies, including:
dry screw pumps, Roots boosters, liquid ring pumps, rotary vane pumps, rotary piston pumps, scroll pumps, claw pumps and complete vacuum systems.
The available quality and engineering capability vary significantly between manufacturers.
What Should I Ask a Chinese Vacuum Pump Supplier Before Ordering?
Ask the supplier to confirm the expected pumping capacity at your actual operating pressure.

For system projects, request a complete scope of supply rather than only individual pump model numbers.
Conclusion
Choosing a vacuum pump manufacturer in China should not begin with a list of factory prices.
The correct sequence is:
Define the Process → Select the Pump Technology → Compare Manufacturer Capability → Verify Performance Data → Evaluate System Scope → Request a Quote
China has manufacturers covering dry screw, Roots, liquid ring and other vacuum technologies, but their strengths differ considerably.
For chemical, pharmaceutical and other industrial processes, the strongest supplier is usually the one that can understand the gas conditions, calculate the required operating point and configure a pump or system around the real application.
If you already know your required pressure, pumping speed and gas composition, send the operating parameters to Vacculex for an initial pump or vacuum-system recommendation.
