Introduction
Haimen Haizhen Vacuum Equipment Co., Ltd. (海门市海真真空设备有限公司) is a Chinese manufacturer of vacuum equipment and roots blowers headquartered in Haimen, Jiangsu, China. The company is described in industry and exhibition listings as a maker of vacuum pumps, vacuum units, and related custom-engineered products, with applications concentrated in industrial processes that require controlled gas removal, pressure reduction, or pneumatic conveying.
The company’s published profile presents it as an established manufacturer with roots dating to 1969, while other business and patent databases identify the corporate entity as founded in 2002 and note continuity from a predecessor vacuum pump factory. This suggests a common pattern in Chinese industrial firms: a long operating lineage under an older factory name, followed by later corporate reorganization under the current legal entity.
Haizhen’s product portfolio includes roots vacuum pumps, rotary vane vacuum pumps, oil-free vertical vacuum pumps, water ring vacuum pumps, clover roots blowers, and a range of roots vacuum units, along with non-standard design and manufacturing services. A technical project description associated with the company also references slide valve vacuum pumps, reciprocating vacuum pumps, and process requirements such as clean vacuum generation, air cooling, oil-free operation, and recovery of exhaust gas, indicating a focus on industrial vacuum systems that must balance performance with environmental and operational constraints.
The company is positioned in a segment of the plastics and process-equipment ecosystem that supports downstream manufacturing through vacuum generation, gas handling, drying, conveying, and process stabilization. Its products are used across industries including vacuum coating, vacuum heat treatment, vacuum drying, wastewater treatment, pneumatic conveying, aquaculture, pharmaceuticals, chemicals, metallurgy, power generation, ports, and textiles. Exhibition records also show recurring participation in pharmaceutical and chemical industry fairs, underscoring its role as a supplier to process industries that depend on reliable vacuum technology.
History and Development
- The company’s lineage is traced to 1969, when its predecessor factory is said to have been founded in Haimen, Jiangsu.
- Corporate database records identify 2002 as the founding year of the current company name, indicating a later formal establishment or restructuring of the business entity.
- Public award notices from Haimen list the company among the district’s industrial enterprises recognized in 2021, showing that it remains an active and locally significant manufacturer.
Business Operations and Segments
Haizhen operates as a manufacturer rather than a trading company, according to supplier and exhibition records. Its business is centered on the design, production, and customization of vacuum pumps, blowers, and integrated vacuum units.
Its operations appear to include:
- Standard vacuum pumps for industrial applications.
- Roots vacuum units and system assemblies for process integration.
- Non-standard product design and manufacturing, which implies adaptation to customer-specific process conditions or installation requirements.
- Custom vacuum-system engineering for sectors requiring specialized pumping curves, clean-vacuum performance, or moisture- and solvent-handling capability.
Products and Technologies
The company’s public materials indicate a product mix built around established industrial vacuum technologies.

The most clearly documented environmental angle in the available material is the company’s emphasis on oil-free operation, tail-gas recovery, and clean vacuum generation in at least one product-development description. Those features are relevant to industrial efforts to reduce oil contamination, manage exhaust streams, and lower water use in vacuum systems.
At the same time, the company is also associated with conventional vacuum technologies, including water ring and rotary vane pumps, which remain widely used because of their robustness and cost-effectiveness in industrial settings. As with many equipment manufacturers in this segment, the environmental profile depends heavily on the final configuration, operating conditions, and customer application.
Financial Performance and Economic Impact
Publicly available sources in the search results do not provide audited revenue, profit, or export figures for Haizhen. However, the company’s presence in local industrial recognition lists and repeated trade-show participation indicate sustained commercial activity and relevance in its regional manufacturing base.
Its economic impact is likely concentrated in:
- Local manufacturing employment and skilled machining work.
- Supply-chain demand for castings, machined parts, motors, seals, and control components.
