In the aluminium production industry, efficient wastewater treatment is critical for environmental compliance, operational safety, and long-term sustainability. Facilities must handle corrosive fluids, acidic compounds, and sludge mixtures with precision and reliability to maintain balance in chemical processes and meet discharge standards.
The Ovell 1-inch and 1.5-inch diaphragm pumps, built with polypropylene (PP) housings and PTFE diaphragms, are engineered to meet these specific needs. Designed for dosing and fluid transfer in chemically aggressive environments, these pumps offer durable, low-maintenance, and leak-free operation for demanding treatment applications.
This article explores the features, advantages, and applications of Ovell’s diaphragm pumps and how they support efficient wastewater neutralisation in aluminium production facilities.
Traditional pump systems often face performance issues when transferring corrosive or high-viscosity fluids, especially in facilities that manage pH-sensitive wastewater. The diaphragm pump, however, is designed to overcome these limitations, offering:
• Chemical Resistance: Materials selected to withstand strong acids and alkalis.
• Precision Flow Control: Ideal for dosing specific chemicals into treatment lines.
• Sealed Operation: Leak-free design helps maintain a safe work environment.
• Air Operation: Eliminates electrical hazards in wet, chemically active areas.
With a robust housing and chemically inert diaphragm, Ovell’s diaphragm pumps are well-suited to move aggressive liquids while maintaining consistent performance and plant safety.
Ovell’s industrial-grade diaphragm pumps are purpose-built for the rigours of chemical processing in wastewater treatment. Here’s what makes them ideal for aluminium production environments:
1. Chemical-Resistant Materials for Harsh Fluids
• Constructed from polypropylene, a strong, corrosion-resistant plastic suitable for harsh chemical applications.
• Equipped with a PTFE diaphragm that is inert and compatible with a wide range of acids and alkalis used in pH neutralisation.
• All fluid-contact parts are built for longevity, ensuring safe operation and minimised chemical degradation over time.
2. Versatile Sizes for Specific Treatment Needs
• 1-inch models are used for dosing chemicals with high accuracy in the neutralisation process. Each pump is assigned to a single chemical to prevent cross-contamination and support automated flow control.
• 1.5-inch models are designed for high-volume fluid transfer, including untreated wastewater and post-neutralisation outflows. These pumps also manage water-sludge mixtures during processing stages.
3. Air-Powered, Safe-to-Use Design
• Operates without electricity, reducing risks in hazardous areas with wet conditions and chemical vapours.
• Simple air system integration allows flexible placement across plant infrastructure.
• Supports safe and reliable operation during fluctuating pressure or flow demand.
Industrial plants demand reliable, efficient systems that can withstand the daily wear of processing chemicals. Ovell’s diaphragm pumps deliver numerous performance and maintenance advantages:
1. Easy Maintenance with Long Service Life
• Minimal moving parts and corrosion-resistant design reduce the risk of mechanical failure.
• Routine checks are simple, and diaphragm replacement is fast and straightforward with basic tools.
• Long-lasting PTFE diaphragms and PP housings reduce frequency of replacements.
2. Consistent and Safe Fluid Movement
• Stable performance ensures accurate dosing during critical pH adjustment stages.
• Air-powered diaphragm operation eliminates concerns over electrical faults or overheating.
• Closed system prevents exposure to hazardous materials, safeguarding personnel and equipment.
3. Lower Operational Costs
• Durable components reduce maintenance labour and part replacement frequency.
• Leak-free operation means fewer product losses and reduced contamination risk.
• Compatible with existing industrial piping systems for easy retrofitting.
At a fully operational electrolytic aluminium production facility, Ovell’s diaphragm pumps play a central role in the plant’s wastewater treatment process. More than a dozen diaphragm pumps—ranging from 1-inch to 1.5-inch models—are actively used across the treatment line, where precise chemical control and corrosion resistance are essential.
Each pump is built with a polypropylene housing and PTFE diaphragm, ensuring long-term durability and compatibility with highly corrosive acidic and alkaline solutions commonly used in pH neutralisation processes.
Applications within the facility include:
• Chemical Dosing – 1-inch diaphragm pumps are dedicated to specific neutralising agents, feeding acids or alkalis into wastewater lines with precise, automated control for accurate pH balance.
• Bulk Wastewater Transfer – 1.5-inch models handle large volumes of untreated wastewater before neutralisation and move treated fluids to the next stage, supporting continuous flow between treatment units.
• Sludge Transport – These pumps efficiently transfer water-sludge mixtures generated during processing, helping maintain throughput and prevent system blockages.
By integrating Ovell’s PP/PTFE diaphragm pumps into critical process points, the aluminium facility ensures consistent treatment performance, operational safety, and reduced maintenance demands in one of the industry’s most chemically demanding environments.
Facilities that process aluminium must maintain high standards of chemical handling and wastewater treatment. Ovell’s PP/PTFE diaphragm pumps support these operations by offering:
• Stable, Contamination-Free Transfer – Closed design and chemical resistance ensure safe fluid movement.
• Operational Flexibility – Models are tailored for both low-volume precision and high-volume transfer.
• Compliance and Efficiency – Helps facilities meet strict environmental regulations while maintaining plant uptime.
• Proven Durability – Built with long-lasting materials that resist the effects of strong industrial chemicals.
For plants working to optimise safety, sustainability, and performance, these diaphragm pumps are a reliable, cost-effective solution.
For industrial sites involved in aluminium production, proper wastewater handling is essential. The Ovell 1-inch and 1.5-inch PP/PTFE diaphragm pumps offer a robust, low-maintenance, and chemically resistant solution for both chemical dosing and fluid transfer.
With safe, closed-system operation and compatibility with aggressive liquids, these pumps help facilities maintain efficient processes while reducing downtime and risk. Whether it's neutralising acidic discharge or transporting treated water, Ovell diaphragm pumps provide long-term reliability and compliance in challenging industrial environments.
