A Flux solvent transfer pump is specifically engineered to handle a wide range of volatile and flammable liquids safely and efficiently. Below are some examples of common solvents that Flux Pumps can transfer:
Toluene is a low-viscosity solvent commonly blended in petrol. The paints and coatings industry also uses Toluene for thinning paints, lacquers and coatings, ensuring smooth application and finish. Alternative uses include the production of pharmaceuticals, dyes and cosmetic nail products.
Acetone is a strong solvent, widely used for cleaning and degreasing machinery. With its ability to dissolve tough residues, it is used in electronics, plastics and textiles manufacturing.
Industries widely use methanol in the production of chemicals, cleaning products, plastics, paints, adhesives, and construction materials. It is also an important clean burning fuel, or fuel additive, for vehicles, boilers and stoves.
Isopropanol is a versatile solvent primarily used as a cleaning agent. Used it as a disinfectant, anti-bacterial agent and astringent in medical applications, and in the production of sanitisers and perfumes.
Ethanol is one of the most widely used flammable liquids. Its uses are many and varied: production of alcoholic beverages, spirits, sanitisers, cosmetics, pharmaceuticals, preservatives and polishes. Plus in manufacturing of plastics and rubber products. Bio-ethanol is used as a fuel additive for vehicles and as fuel for fireplaces. Ethanol is the intoxicating ingredient in alcoholic drinks.
Methylene Chloride is a common solvent frequently used to dissolve organic compounds e.g. in paint stripper. It is also used in adhesives, acrylics, chemical processing, metal cleaning and degreasing applications. Flux offers robust, reliable pump solutions for the controlled transfer of methylene chloride, reducing exposure risks and enhancing operational safety.
Yes, Flux offers explosion-proof ATEX certified pumps and motors, specifically designed for transferring solvents and flammable liquids in hazardous environments. Firstly, these ATEX-certified products have specially designed features to reduce the chance of igniting flammable air-vapour mixtures in Zoned areas. The F 430 Ex features robust construction, Zone separation, plus earth bonding point to provide reliable and safe solvent transfer. Both electric and compressed air operated ATEX motors are available.
Flux offers competitively priced, ready-to-use, pre-assembled pump kits for many applications. Consider our kits for highly flammable media, 99.9% emptying or universal applications. In each case components are conductive and Ex-approved, therefore, meeting strict safety standards for handling low-flash solvents. Each kit includes 2 m dispense hose, hand nozzle, earth cable and compression gland to secure the pump in an IBC or drum. The hand nozzle provides a safe, controlled dispensing method and, moreover, is approved for use with flammable liquids.
Firstly, you must use a pump and motor with an appropriate ATEX rating, as these pumps are safe to use in explosive atmospheres and have earth bonding points. An earth cable ensures that any static electricity created by the pump and motor dissipates safely.
Reduce the risk of electrostatic charge creation in liquids by reducing flow rates. You can achieve this by reducing motor speed or increasing pipe bore size. Remember that filtration, separation and mixing can increase electrostatic charge in liquids. This raises the risk of static discharge and an associated spark that could ignite flammable vapour-air mixtures.
Other situations to avoid include splash-filling, pipe runs with excessive restrictions (e.g. bends, valves and filters), as these can elevate electrostatic charge. Additionally, use conductive hoses and fittings to dissipate electrostatic charge from the entire pumping system. Finally, ensure that you fill containers that are conductive, fitted with an earth cable, or placed on conductive flooring.
To ensure precise filling of solvents into canisters, Flux recommends using the Flux F 430 S Ex drum pump with a mechanical seal and Ex certification. This pump is ideal for low-viscosity, aggressive and highly flammable media. When combined with F 460-1 Ex commutator motor, FMC 100 flow meter and FSV 121-1 switched-mode amplifier to create a one-touch dispensing solution, smaller containers can be filled accurately with minimal waste.
The FLUXTRONIC® batch controller allows the user to select a predefined fill quantity at the push of a button. After reaching the selected volume, the pump automatically shuts off. The system is designed for safely filling solvents, ensuring consistent, reliable results.
To meet the needs of a gin manufacturer transferring ethanol from IBCs to their stills, Flux provided a portable pump trolley with earth-bonded ATEX (Ex) and food-safe components. This mobile solution is designed for use in hazardous areas and ensures products can be dispensed safety in many areas of the distillery. The F 430 series pump, made from stainless steel 316 with FKM seals, meets FDA and EN 1935 food certifications. The system also includes an Ex IP 55 drive motor, stainless steel flowmeter and Fluxtronic batch controller for accurate volume control.
The FAE dispense nozzle features a remote start-stop function, enabling operators to stop and restart the pump mid-batch for precise filling. Additionally, dry-run protection ensures the pump shuts off if there is zero flow, preventing damage. Furthermore, it ensures safe, accurate ethanol transfer every time. This solution also reduces the risk of spills and eliminates manual handling, streamlining the customer’s processes.
To automate the transfer of acetone and epoxy resin into 5 kg and 25 kg containers, Flux provided a tailored solution using the Viscopower progressive cavity pump with 230 V single-phase motor. This system allows for the transfer of both high and low viscosity flammable fluids from drums and IBCs. The setup includes an FMO series positive displacement geared flowmeter and an Ex-approved Fluxtronic batch controller. The Fluxtronic is wall-mounted for ease of use.
Conductive flexible hoses connect the pump, flowmeter and RS type dispense valve, which mounts to an adjustable arm. The scissor adjustable table allows operators to easily fill different-sized containers while performing tasks such as labelling and capping. A remote start-stop button on the valve ensures accurate filling without interrupting other duties.
Additionally, the system includes dry-run protection, which automatically shuts the pump off if there is zero flow, ensuring safe operation. Since installation, the system has improved productivity ten-fold and the customer expects to achieve payback on their investment within nine months.
