Its development illustrates the increasing importance of process-equipment suppliers capable of combining international pump technologies with localized engineering and after-sales support.

History and Development

Shanghai Jiyo was founded in 2003 as a distributor and service provider for fluid-transfer equipment. Its early business model focused on representing established international pump manufacturers and supplying equipment to industrial users in China.

Several milestones shaped the company’s subsequent development:

• 2003: The company was established in Shanghai, initially building its business around industrial pump distribution and technical support.
• 2010: Jiyo established equipment-assembly and processing capabilities together with a professional testing platform, expanding its role from product agency into system integration and project delivery.
• 2014: Shanghai Jiyo was listed on China’s National Equities Exchange and Quotations under stock code 831533, according to corporate-information records.
• 2016: The company formed a strategic cooperation relationship with Swiss automation-technology supplier Rocksensor, adding pressure and temperature sensors, transmitters, and flowmeters to its broader process-equipment offering.
• Subsequent development: Jiyo expanded its activities into plastic-pelletizing systems and developed proprietary product lines, including the SeficoPower air-operated diaphragm-pump brand and the ZOOM plastic-pelletizing system.

This progression reflects a broader pattern in China’s industrial-equipment sector: companies that began as distributors increasingly added engineering, assembly, automation, and service capabilities to address customers seeking complete process solutions rather than individual components.

Business Operations and Segments

Jiyo’s business can be grouped into three closely related activities.

Fluid-transfer equipment distribution

The company supplies pumps and related equipment from international manufacturers. Reported partner and product brands include Tuthill, PSG brands such as Wilden, Blackmer, Mouvex, Griswold, Alm atec, and EnviroGear, as well as Maag, PPI, Serfilco, SEKO, FTI, and other specialized suppliers.

This distribution activity gives customers access to equipment designed for abrasive, viscous, corrosive, volatile, or otherwise difficult-to-handle media. It also requires application engineering because pump performance depends on fluid viscosity, solids content, temperature, pressure, flow rate, chemical compatibility, and the required degree of metering accuracy.

System integration and engineering services

Jiyo provides project-oriented services covering:

• Process-scheme design
• Pump selection and sizing
• Fluid-system calculations
• Equipment matching and package assembly
• Automation and instrumentation integration
• Installation and commissioning
• Maintenance and technical support

The company’s reported experience covers more than 300 fluid-handling process applications, while its customer base has included hundreds of foreign-invested and industrial enterprises in China. Such experience is particularly relevant to plastics and chemical plants, where pumps are often integrated into larger systems for raw-material transfer, additive dosing, filtration, extrusion support, solvent handling, and product recovery.

Manufacturing and proprietary equipment

In addition to representing external brands, Jiyo markets proprietary products. These include the SeficoPower air-diaphragm-pump line and the ZOOM plastic-pelletizing system. The combination of proprietary equipment, third-party machinery, and engineering services allows the company to participate at several points in the equipment value chain.

Products and Technologies

Pump technologies

The company’s principal pump categories include:

• Air-operated double-diaphragm pumps: Suitable for intermittent or variable-flow service and for transferring liquids containing solids or requiring leak-resistant handling. Pneumatic drive systems can be advantageous in hazardous or washdown environments because the pump does not require an electric motor at the point of operation.
• Gear pumps: Positive-displacement pumps commonly used for viscous fluids, lubricants, polymers, resins, and other materials requiring relatively stable volumetric delivery. Their practical performance depends on gear geometry, internal clearances, operating temperature, and the viscosity of the conveyed medium.
• Vacuum pumps: Used in evacuation, degassing, drying, filtration, vacuum conveying, and process-support duties.
• Vane pumps: Applied in liquid-transfer services where smooth flow and compact construction are required.
• Metering and dosing pumps: Used to deliver controlled quantities of chemicals, additives, catalysts, solvents, and treatment agents.
• Centrifugal pumps: Listed among the company’s equipment categories for applications involving comparatively lower-viscosity fluids and higher-volume transfer duties.

Pump selection in plastics production requires attention to shear sensitivity, melt temperature, solids loading, contamination risk, pressure pulsation, and compatibility between wetted materials and the process medium. In polymer-related applications, positive-displacement pumps are often preferred where a controlled flow is required for viscous or high-temperature materials.

Plastic-pelletizing systems

Jiyo also supplies plastic-pelletizing equipment under the ZOOM name. Pelletizing systems convert extruded polymer strands or melt streams into granules suitable for transport, blending, storage, compounding, and subsequent processing.

Depending on configuration, a pelletizing line may include:

• Extruder-to-die connection equipment
• Strand or underwater cutting arrangements
• Cooling and solidification systems
• Pellet dryers
• Screening and classification equipment
• Conveying and collection units
• Process monitoring and control components

Pellet quality is influenced by die design, cutting geometry, melt temperature, cooling conditions, residence time, strand stability, and the polymer’s rheological properties. Consistent pellet dimensions and low fines generation are important for downstream feeding, blending, and packaging.

Instrumentation and automation

Through its cooperation with automation and measurement suppliers, Jiyo has expanded beyond mechanical equipment into process instrumentation. Relevant devices include pressure sensors, temperature sensors, transmitters, and flowmeters. These components help monitor operating conditions and support closed-loop control, fault detection, energy management, and production consistency.

Applications and End Markets

Jiyo serves a broad range of process industries. Its principal application sectors include:

The diversity of these sectors reduces dependence on a single downstream market, although it also requires broad technical competence and the ability to manage different regulatory, safety, and materials-compatibility requirements.

Global Presence and Market Position

Shanghai serves as the company’s principal operating base. Reported offices or branches have included locations in Hong Kong, Beijing, Guangzhou, Hangzhou, Wuxi, and other Chinese industrial centers, with later company materials also identifying locations such as Jinan, Chengdu, Yixing, and Taiwan.

Jiyo’s competitive position is based less on commodity-scale manufacturing than on application knowledge, equipment availability, brand representation, local engineering, and service responsiveness. Its reported customer base includes more than 300 process applications and hundreds of foreign-invested enterprises, indicating a focus on technically demanding industrial customers rather than solely on standardized pump sales.

The company competes in a market that includes:

• International pump manufacturers with global service networks
• Chinese pump producers offering cost-oriented equipment
• Specialized system integrators
• Engineering contractors and process-equipment distributors
• Original equipment manufacturers serving plastics, chemical, and pharmaceutical plants

Its role is particularly relevant where customers require equipment from multiple suppliers to operate as a coordinated system. This model can create value through product selection and integration, but it also exposes the company to industrial capital spending cycles, import conditions, foreign-exchange movements, and the changing strategies of represented brands.

Research and Development

Jiyo’s technical development has centered on adapting equipment to industrial applications and broadening its product and engineering capabilities. The company’s reported investment in assembly facilities, testing infrastructure, instrumentation, and proprietary pump and pelletizing products indicates a progression beyond pure trading activities.

Areas of technical development include:

• Integration of pumps with sensors and process controls
• Equipment packages for specialty fluids and gases
• Plastic-pelletizing and cutting systems
• Improvements in installation, commissioning, maintenance, and troubleshooting
• Development and commercialization of proprietary equipment brands

For plastics manufacturers, this type of applied development can be significant because equipment performance depends heavily on the interaction between pump design, polymer formulation, temperature control, extrusion conditions, and automation. Improvements in monitoring and process integration can help reduce unplanned downtime and improve consistency, even where the underlying pump or pelletizer technology is established.

Sustainability and Environmental Considerations

The company’s equipment contributes indirectly to environmental performance through applications in water treatment, waste handling, process-efficiency improvement, and chemical dosing. Pumps and control systems can support more accurate use of treatment chemicals, reduce leakage, and improve the reliability of industrial processes.

In plastics manufacturing, system design also affects resource efficiency. Stable transfer and metering may help reduce off-specification production, while effective pelletizing can improve material recovery and downstream handling. However, the environmental performance of a pump or pelletizing line depends on the complete system, including motor efficiency, operating point, maintenance condition, process losses, cleaning requirements, and the fate of products at end of life.

Plastic-pelletizing equipment is relevant to both virgin-polymer and recycled-polymer operations. In recycling applications, reliable cutting, cooling, drying, and classification are important for producing pellets with consistent dimensions and moisture levels. These factors influence the usability of recycled material in compounding and subsequent manufacturing.

Financial Performance and Economic Impact

Corporate-information databases identify Shanghai Jiyo as a company listed on China’s National Equities Exchange and Quotations under code 831533, with a listing date of December 18, 2014. Company and industry-directory profiles have reported annual sales above RMB 100 million, while later company materials have stated sales above RMB 200 million; these figures should be interpreted according to the reporting period and source context.

The company’s economic contribution arises primarily from its role in industrial supply and technical services. Its activities support:

• Procurement of specialized pumps and process equipment
