Engineered for reliability, chemical resistance, and long life under challenging tropical industrial conditions.
In the evolving industrial landscape of West Africa, precision fluid control and negative pressure management systems are becoming critical components of operational efficiency. The city of Banfora, Burkina Faso, situated within the Cascades Region, serves as an agricultural and sugar processing powerhouse. Historically reliant on mechanical processing methods, regional enterprises—such as sugar packaging mills, bio-chemical research hubs, and mango dehydration operations—are shifting toward optimized vacuum processing systems. Among these, the diaphragm vacuum pump stands out as a foundational piece of equipment due to its dry, oil-free mechanics, low maintenance profile, and unmatched adaptability to harsh environmental conditions.
Unlike mature Western industrial hubs, operations in Banfora face unique logistical and operational challenges, including high ambient operating temperatures, dust-laden air during the dry season, and fluctuating power parameters. A high-efficiency, oil-free diaphragm pump addresses these realities directly:
On a global scale, the vacuum equipment market is witnessing a rapid structural transition. Industries are moving away from traditional oil-lubricated rotary vane systems in favor of dry, multi-stage diaphragm configurations. The key drivers behind this shift include:
How Shandong Tongyi Machinery Equipment Co., Ltd delivers premium vacuum solutions with cost-performance efficiency.
Our factory utilizes advanced CNC lathes, automated horizontal machining centers, and large-scale floor boring machinery. This high-precision infrastructure ensures tolerances are held to micrometer levels, drastically reducing wear on elastomeric diaphragm surfaces.
Every batch of diaphragm pumps undergoes intensive performance profiling. Our systems measure ultimate vacuum pressure, flow rates, and noise levels over extended periods, meeting international ISO and CE compliance metrics before leaving the assembly line.
We provide optimized sea and air freight routing to West Africa via key regional ports (such as Lomé and Abidjan) with reliable inland container transit directly to Banfora, backed by virtual engineering support and readily available replacement parts.
Supporting chemical metering, multi-agent input, and high-performance laboratory applications in Cascades and beyond.
Shandong Tongyi Machinery Equipment Co.,Ltd is a professional manufacturer of vacuum pump, water pump, slurry pump and other industrial pumps. In line with the concept of "science and technology leading, quality oriented, and reputation first", the company has made great efforts to innovate and forge ahead, so that excellent results have been achieved in the production and operation, new product development and other aspects of the company.
Shandong Tongyi Machinery Equipment Co., Ltd has built a legacy on engineering resilience. Rooted in traditional industrial manufacturing, we have continually integrated smart automation and modern quality controls. Over the decades, we transitioned from serving regional Chinese projects to supplying heavy duty pumping installations across Asia, Eastern Europe, South America, and African industrial sectors. Our commitment to engineering research and development has secured several proprietary designs in vacuum pump configuration, guaranteeing longer operational lifespans under intense cyclic loads.
The company has modern standard workshop, with a complete scientific quality management system. There are many advanced, professional production equipment and testing instruments. By maintaining a clean, structured workspace, we minimize dust contamination during diaphragm assembly—a crucial factor in preventing premature failure in micro-vacuum valves and high-integrity PTFE layers.
Our main products are SZ, SZB, SK, 2BV, 2BEA, 2BEC series water ring vacuum pump, roots water ring vacuum unit, closed cycling vacuum unit, WLW vertical oil-free reciprocating vacuum pump, etc. We also produce SH, S, OS, IS, ISG, LG, DL, DA1 series water pump, YZ, YW series vertical slurry pump, GMZ, ZJ series horizontal slurry pump, QW series submersible sewage pump, DYWS series submerged pump, WSL series submerged No-clog pump, PW series horizontal sludge pump, IH series chemical pump, YHF series submerged anti-corrosive pump, FSB series fluorine plastic centrifugal pump, and at the same time also produces self-priming pump, automatic water supply equipment.
Products are widely used in petroleum, chemical industry, electronics, mining, metallurgy, plastic-machinery, dye chemical, brick machinery, low-temperature equipment, paper making machinery, medicine chemical, food machinery and other fields. Our vacuum solutions are particularly valued in settings requiring volatile compound extraction, sterile fluid transfers, and harsh slurry handling.
Our manufacturing capacity is anchored by high-speed CNC lathes, industrial multi-axis drilling machines, heavy machining centers, large floor boring machines, and other advanced processing equipment. This tooling allows us to maintain exceptional concentricity and planar tolerances, reducing friction losses and heat buildup in our finished pump assemblies.
The company has a perfect pre-sales service reception, sales production supervision and management, after-sales service guidance and other perfect service system. We provide comprehensive operational manuals, video installation guides, and remote consultation to help local engineering teams in Banfora and across West Africa deploy and maintain our pumping assemblies safely.
Engineered for clean, low-maintenance operations in lab diagnostics, chemical metering, and packaging systems.
Technical advice for choosing and maintaining industrial vacuum pumps in challenging environments.
Oil-free diaphragm pumps eliminate the need for lubricating oils. This prevents hydrocarbons from back-streaming into samples or being released into the laboratory air. In agricultural labs like those in Banfora, it prevents contamination of food-grade sugar and agricultural testing samples while reducing routine filter maintenance costs.
High dust concentrations and ambient temperatures of over 40°C in the Cascades region can cause motor overheating and micro-valve clogging. We recommend installing external particulate pre-filters on the inlet line and placing the pump in a well-ventilated space. Our models feature thermally protected motors to prevent damage during prolonged periods of high heat.
Yes, our laboratory line features PTFE (Polytetrafluoroethylene) heads and diaphragms. These pumps are designed to resist acidic vapors and solvents like ethanol and acetone, making them highly effective for chemical processes that degrade standard rubber parts.
Depending on order volume, we offer sea shipment to the Port of Abidjan (Ivory Coast) or Port of Lomé (Togo), followed by direct overland rail or truck transport to Banfora. Air freight is available to Ouagadougou International Airport for urgent replacements, followed by direct transport to the Cascades region. The standard shipping timeline ranges from 30 to 45 days by sea and 7 to 10 days by air.
Our engineering team is ready to assist you in designing a customized vacuum package that meets your project's volume, chemical resistance, and power supply specifications.
