Polypropylene tank transfer pumps for corrosive liquids

Flux polypropylene pumps – Vertical and horizontal pumps for heavy-duty chemical transfer

Flux Pumps are experts in the production of polypropylene pumps for chemical handling applications. From our smallest JuniorFlux barrel and container pumps, to our legendary F 430 drum pump, right up to our high-flow 700 series high-flow chemical transfer and circulation pumps, polypropylene pump production is at the core of our business.  

Flux 600 and 700 series polypropylene pumps are the ideal solution for demanding tank transfer and circulation applications. These heavy-duty centrifugal immersion pumps handle aggressive and abrasive media, delivering flow rates up to 74 m³/hr and pressure up to 3.5 Bar. They are particularly effective for the continuous circulation or transfer of chemicals, plating solutions, acids, alkalis and waste effluent. 

Constructed from high-quality, virgin polypropylene (PP), these pumps deliver the superior chemical resistance required for many corrosive environments. Furthermore, polypropylene pumps are an excellent choice for industrial acid and alkali handling applications, when chemical resistance is essential. Note that Flux chemical transfer pumps are available in alternative materials, such as PVDF and stainless steel, thereby covering a huge range of chemical and thermal compatibility. 

Our F 600 and F 700 polypropylene vertical immersion pumps are available in both seal-less and mechanically-sealed designs, thereby covering a wide range of duties, including pumping solids-entrained or abrasive media. Furthermore, these pumps are available to order in lengths from 300 mm to 4100 mm, to suit various tank sizes and transfer flow rates. Plus horizontal TR series models are also available for dry installation below tanks or process vessels. 

For robust performance, Flux high-flow chemical transfer and circulation pumps can be supplied with IP 55 three-phase electric drive motors, ranging in size from 0.37 kW to 5.5 kW.

Polypropylene pumps - FAQs

Firstly, the term polypropylene pump refers to any pump constructed from polypropylene, a structurally durable, thermoplastic material known for its resistance to abrasion, high temperatures and corrosion. Polypropylene is relatively inexpensive, freely available and can be easily moulded into complex shapes.  

Polypropylene pumps are durable, lightweight and chemically resistant, with a long lifespan, even under demanding duty cycles. These characteristics ensure polypropylene pumps are common. They are widely used for chemical transfer, chemical processing, water treatment and effluent handling processes.  

Flux F 400, F 600 and F 700 Series polypropylene pumps utilise our unique steel-cored inner tube. This gives our pumps unrivalled driveshaft and mechanical seal support, essential for extending service life. The steel core is over-moulded with polypropylene, thereby ensuring there is no contact with the pumped media. The steel core also enhances material stability at high temperatures. 

The key difference between immersible and submersible pumps lies in the degree of submersion and the design features: 

  • Immersible pumps: Only the pump shaft and impeller are submerged in the liquid. The motor remains above the liquid surface. Immersion pumps are often bolted in place and therefore designed for permanent installation. In addition, immersion pumps are often specified for handling corrosive fluids, when there is higher risk of damage through chemical attack. For example, a simple seal failure on a submersible pump could lead to costly motor repairs. In contrast, choosing a seal-less immersion pump eliminates this risk.  
  • Submersible pumps: Both the mechanical pumping components and the motor are fully submerged in the liquid. Submersible pumps are generally compact and portable, whereas comparable immersible pumps are longer and heavier. Submersibles are commonly used for deep-well water pumping, drainage, slurry handling, irrigation or sewage handling systems. They are sometimes fitted with blades to break up semi-solid waste matter. The sealed design protects the motor from the surrounding liquid.
