In water and wastewater treatment facilities, chemical pumps play a crucial role in transporting chemicals such as sodium hypochlorite (liquid chlorine), sodium hydroxide and hydrochloric acid to purify and disinfect water. This essential process ensures the delivery of clean, safe drinking water to communities. FLUX Pumps offers a comprehensive range of chemical pumps engineered to transfer a wide variety of treatment chemicals, including polymers, acids, alkalis and disinfectants from drums and IBC containers.
Whether you’re using sodium hypochlorite for disinfection or working with ferric chloride or sulphate to support floc formation, our pumps provide a reliable, high‑performance solution. They meet strict quality standards and comply with regulatory requirements. From dosing smaller quantities from 25‑litre drums to managing bulk fluid transfer from IBCs, our chemical transfer pumps deliver consistent, dependable operation. Moreover, our lightweight Junior and Combi pumps are ideal for use with swimming pool disinfectants too.
Flux chemical pumps are trusted by engineering contractors and utility providers across the UK for the precise decanting and transfer of chemical additives and flocculants used in water and wastewater treatment. Our pumps support safe, efficient handling of treatment chemicals such as citric acid, aluminium sulphate, ferric chloride and PAC, helping maintain effective floc formation and removal of suspended solids.
Designed to handle a wide range of chemicals, including acids, alkalis and disinfectants. Our chemical pumps ensure safe and efficient operation in demanding environments. For example, we build our pumps to resist the corrosive effects of hydrogen peroxide and sodium chlorite, ensuring long-term durability.
A choice of pump designs and motors (battery, 110 V or 230 V powered) allows Flux to offer the perfect solution for your application. Therefore, Flux ensures optimal performance in any water or wastewater treatment application. Whether transferring phosphoric acid to prevent pipe corrosion, or pumping sodium molybdate to inhibit rust, our pumps can meet your requirements.
Engineered for durability and ease of maintenance, Flux pumps minimise downtime and reduce operational cost, while delivering consistent performance over time. Furthermore, their robust construction and high-quality materials guarantee reliable operation, even with abrasive or hazardous substances.
Flux chemical pumps are essential for the efficient and safe transfer of chemicals critical to water and wastewater treatment. Their versatility and durability make them a reliable choice for handling a range of liquids. And unique FLUX design features ensure seamless operation in demanding environments.
Industries use Flux wastewater treatment pumps to transfer:
When choosing a pump for transferring chlorinated water, it's essential to select one that ensures chemical resistance, durability and efficiency. Flux offers a range of hypochlorite and bleach transfer pumps specifically designed for this purpose, featuring corrosion-resistant materials such as polypropylene, PVDF and PTFE. These materials are highly resistant to the damaging effects of chlorine, sodium hypochlorite and sodium chlorite.
Additionally, our pumps are equipped with a choice of high-quality o-ring materials, reducing risk of leaks and maintaining optimal performance, even with aggressive chemicals. Whether you’re managing swimming pool disinfection using sodium hypochlorite, or using chlorine dioxide precursors like sodium chlorite, Flux Pumps deliver consistent, dependable results.
Yes, Flux prioritises safety in every aspect of pump and motor design. We design our pumps for use in hazardous environments. F 458 series motors are totally-enclosed designs with IP 55 ingress protection and acid resistant paint. This makes our pumps ideal for handling chemicals such as hydrogen peroxide, phosphoric acid, or hydrochloric acid in sensitive water treatment applications.
Because we manufacture pumps from a range of materials, e.g. there is always an option available for safely dispensing any particular chemical. Additionally, our water treatment pumps are available with a choice of o-ring materials such as FKM or EPDM. Careful material selection therefore guarantees safe use with any acid or alkali. In addition, our pumps are light-weight for ergonomic handling, reducing strain and enhancing operator safety during chemical transfer.
While Flux seal-less pumps are optimised for use with clean chemicals, specific models can handle liquids containing small particulates, crystalline solids, or suspended solids. For example, our F 430 pumps are effective in transferring coagulant mixtures like poly aluminium chloride (PAC) and flocculants, which often contain minor solids.
These specialised pumps with mechanical seals, high clearance impellers and wear-resistant materials are capable of pumping solid particles without compromising performance. This flexibility makes Flux pumps suitable for tackling most challenges. For instance, transferring citric acid or ferric chloride in demanding water treatment processes.
Electroplating facilities often need to move large volumes of wastewater containing aggressive acids, alkalis and suspended solids. The FLUX F 640 PP centrifugal immersion pump provides a dependable solution for this environment. Designed specifically for abrasive and corrosive wastewater, it can operate continuously thanks to it’s three‑phase motor and heavy-duty construction. Pumps can be supplied in custom lengths to suit different tank depths.
The pump is secured to the tank using a bolted flange to maintain stability and performance at varying immersion levels. A built‑in inlet strainer prevents larger particles from entering the pump, and the system can be automated with level‑monitoring control for safe, efficient operation.
For applications involving abrasive slurries or wastewater with high particulate content, FLUX air‑operated diaphragm pumps offer a robust solution. The RFM 25 and RFM 40 models are compact, self‑priming chemical pumps designed for viscous media and solids‑laden wastewater.
Their high‑clearance check valves and positive displacement design minimise internal friction, as there are no rotating parts. Capable of generating discharge pressures up to 8 bar, these pumps deliver consistent flow rates across varied transfer distances. Flow can be precisely controlled using an air inlet regulator, while the integrated silencer ensures quiet operation in enclosed environments.
