The F 458 motor is purpose-built for operation in corrosive atmospheres, humid environments, or food production areas where equipment reliability and resilience are essential.

Double-shell aluminium casing

Unlike our lightweight IP 24 motors, the F 458 utilises a reinforced double-shell aluminium casing, providing mechanical strength, low noise, shock resistance and thermal insulation.

In addition, the externally ventilated housing protects the motor internals from humidity and ingress of corrosive fumes. Therefore, this drum and container pumps motor is ideal for tough industrial applications and heavy-duty use.  

Its IP 55 ingress protection rating provides protection against splashing liquids, indirect water jets and dust, extending service life in chemical manufacturing sites, metal plating shops and wastewater treatment plants. Like all Flux drum and container pumps’ motors, F 458 models are serviceable designs with spare parts, such as bearings and brushes, available to order from stock. 

In applications requiring variable flow control, the F 458 EL variant provides stepless electronic speed regulation, consequently allowing operators to fine-tune delivery rates during pumping. Choose the more powerful 700 W F 458-1 model for high-pressure applications or when handling fluids with higher viscosity or density.

Examples include food products, concentrated acids and heavy oils. Therefore, F 458-1 is also suitable for use with F 570 series high viscosity pumps. 

Selecting the correct motor for drum and container pumps requires an understanding of several factors: 

• Power supply available at site 

• Liquid type, viscosity and density 

• Duty cycle 

• Performance requirements (desired flow rate and discharge pressure) 

• Discharge pipework pressure losses 

• Environmental factors, eg. preferred noise level, humidity, presence of corrosive fumes 

• Hazardous area classification, as determined by DSEAR assessment 

F 458 choices

Choose the F 458 motor for tough duty cycles and challenging environmental conditions, where standard internally cooled IP24 drum pump motors may fail prematurely due to water, dust, or corrosive fume ingress. Note however, that F 458 is not Ex-certified and is thus unsuitable for use in areas where flammable vapours are present.  

The standard 460 W model supports continuous operation with low to moderately viscous fluids such as cleaning chemicals, alcohols and light acids. Choose the high-power F 458-1 variant for handling high-density or high-viscosity fluids, or when pumping over longer horizontal or vertical distances. F 458-1 is also compatible with F 570 high viscosity pumps. 

If your application demands variable flow rates – especially useful for dosing, filling, or transfer into smaller vessels, the F 458 EL with electronic speed control enables real-time flow adjustment. 

All variants of the F 458 motor are compatible with Flux F 400 series drum and container pump tubes, including those made from polypropylene, stainless steel, aluminium and PVDF, plus special models, such as the F 426 mixing pump. Therefore, you can use the F 458 to handle a wide range of media types.

Both the F 458 and F 460 Ex are engineered for use in tough, industrial drum and container pumping systems. Their motor housings are very similar in design and appearance, being double walled, externally cooled designs.  

Both models have IP 55 protection against dust and water ingress. Power outputs are also identical, ie. standard models are 460 W and the high power models are 700 W. Moreover, both motors offer a variable speed control option, designated by the EL model code. They are both designed for continuous duty cycles and the paint finish is identical (but the colours are different). So, what are the differences?  

ATEX- certification

The most important difference is that F 460 Ex is ATEX-certified, making it suitable for use in hazardous areas (DSEAR Zone 1/2), where flammable air-vapour mixtures may occur. F 460 Ex incorporates zone separation features.

These features ensure a flashfire is contained within the motor housing in the unlikely event of such an occurrence. Therefore, you can potentially use the F 460 instead of the F 458, but not vice versa. 

The ATEX design regulations mean the F 460 Ex motor incorporates numerous small design changes compared to F 458. For example, the shaft sealing arrangement uses only one o-ring instead of two.
