Explosion-risk zones

Firstly, the Flux F 460 Ex motor is the clear choice for professionals pumping from drums and IBC’s in explosion-risk zones, where intrinsically safe, certified equipment is non-negotiable. Furthermore, this explosion proof drum pump motor offers the ideal balance of performance, weight, safety and adaptability, supporting a wide range of hazardous fluid handling tasks.

This includes transferring and dispensing highly flammable solvents, alcohols and fuels.

What sets the F 460 Ex apart is its double-walled, IP 55 housing, which consequently provides protection from dust and liquid ingress. Furthermore, combined with exceptional thermal management and fully-enclosed windings and armature, this motor can handle sustained periods of continuous operation in tough environments.

In addition, corrosion-resistant paint provides resistance against chemical splashes and fumes. Not only that, the motor housing reduces noise output class-leading levels.

F 460 variations

The F 460 Ex EL model, with stepless speed controller, provides precise flow control, thereby making it ideal for metering or filling applications. Meanwhile, the F 460-1 Ex variant boosts power output to 700 W for handling higher density and viscosity fluids, without compromising safety certification.

This model is also suitable for use with F 570 Ex series high viscosity pumps.

Yes, when transferring flammable or explosive liquids, using an explosion proof drum pump motor is essential. Furthermore, the risk of ignition from electrical sparks, motor heat, or static discharge must be eliminated to comply with ATEX (Atmosphères Explosibles) regulations, which apply to equipment used in hazardous areas across the UK and EU.

To determine the right motor for your application:

• Firstly, confirm if your work area is a Zone 1 or Zone 2 classified hazardous location.
• Lastly, ensure the explosion proof drum pump motor is certified to ATEX Directive 2014/34/EU and marked with the red Ex symbol.
• Lastly, check the ATEX classification (IIC, IIB, etc.) and temperature class (e.g. T6 = max 85°C) of the motor and ensure it is suitable for the environment.

The F 460 Ex motor is suitable for atmospheres containing flammable vapours and gases, with its ATEX certification of II 2 G Ex d e IIC T6. However, it is not safe to use in areas with flammable dust-air mixtures.

This motor is also available in a high-temperature (HT) version, making it suitable for use in ambient temperatures up to 60°C. Markedly, for maximum safety, only pair this motor with Flux ATEX-rated pump tubes and conductive hoses.

While both the F 460 Ex and F 416 Ex are explosion-proof motors from Flux, they are designed for use with completely power sources. The F 460 Ex electric motor typically runs on single-phase 230 V or 110 V power supplies, whereas F 416 Ex is powered by compressed air.  Note that both motors are suitable for use in Zone 1/2 hazardous areas.

At 900 W, the F416 Ex delivers the highest power output among our ATEX-approved drum pump motors. However, both F 416 Ex and F460-1 Ex motors are suitable for use with F 400 and F 570 series barrel and IBC pumps.

F 460 Ex vs. F 416 Ex

*ATEX classification for F 460-1 Ex 110 V version is II 2 G Ex de IIC T5 Gb.

What should you choose?

Choose the F 416 Ex when your application demands high (or variable) flow rates, or greater discharge pressure. It is also a good choice for handling higher viscosity, or higher density fluids. Its low weight reduces risks associated with manual handling.

In addition, a compressed air powered motor such as this may be the only option in Ex-zoned areas where electrical power supplies are unavailable.

In contrast, the F 460 Ex runs more quietly, without any requirement for exhaust hose, or a remote mounted silencer. Although our F 416 Ex air motor can be run without lubricating oil, F 460 Ex eliminates any concerns regarding oil contamination.

Additionally, this motors totally enclosed design is a better choice for humid environments and sanitary applications.
