TECO Flameproof Electric Motors are engineered for hazardous environments in mining, oil and gas, water, plus chemical processing applications. Designed to handle pumps, fans and conveyors in explosive atmospheres, all motors offer certified protection, thermal resilience, and long-term reliability.
All models are fully compliant with International Electrotechnical Commission (IECEx) and ATEX requirements, including explosion-proof (Ex d and Ex de) configurations, and are suitable for Zone 1 and Zone 2 areas.
Ex d (Flameproof) motors are designed to contain internal explosions. Ex de (Flameproof + Increased Safety) motors combine Ex d protection with an Ex e terminal box.
The range of underground mining-certified models meets Group I standards, which are typically underground mines with firedamp (methane) atmospheres. In such an environment, motors must comply with IEC 60079-1 (Flameproof enclosures).
The TECO Australia Flameproof Electric Motors are designed for coal applications where flammable gases and coal dust are present, a feature that distinguishes TECO from many imported alternatives not certified for underground applications.
These motors have cast-iron housings, a high-efficiency insulation system that is rated to 155°C (Class F), and are designed with a totally enclosed fan-cooled (TEFC) (IC411) configuration. They’re engineered for continuous operation (S1 duty), where the motor runs at a constant load for a duration long enough to reach thermal equilibrium. It can run at full output in ambient temperatures up to 55°C without any derating.
This makes them ideal for pump applications in harsh Australian conditions, where high thermal performance is crucial to prevent overheating, downtime, and loss of efficiency.
TECO Flameproof Electric Motors are utilised in numerous critical pump systems, ranging from dewatering and slurry pumps at mine sites to chemical dosing skids, fire suppression systems, and oil transfer units in refineries.
They are also suitable for ventilation fans, cooling towers and conveyor drives, offering consistent torque and stable operation even in load-fluctuating conditions.
Their low vibration and noise levels help reduce mechanical stress on pump components, extending the life of seals, impellers and bearings.
One of the key advantages for customers is the ability to access local stock across Australia and New Zealand, avoiding delays.
TECO in-house ModShop can modify motors to suit specific site requirements. This includes rotating terminal boxes, installing anti-condensation heaters, changing cable entries, or making shaft and mounting adjustments. All modifications are carried out in accordance with approved certified procedures to ensure that compliance is maintained.
This means less time lost to sourcing, approvals, or on-site rework for original pump equipment manufacturers (OEMs), system integrators, and maintenance teams.
TECO motors are backed by technical teams that understand local standards and applications. These teams provide engineering support from selection through to commissioning.
Customers using TECO Flameproof Electric Motors benefit from:
- Safer installations compliant with both Australian and International Ex standards
- Longer motor life through superior thermal and mechanical resilience
- Reduced downtime through local support and fast modification service
- Simplified wiring and installation with Ex de options
- Lower total cost of ownership attributed to efficient, low-maintenance operation
TECO offers proven, ready-to-install motor solutions backed by decades of experience and a commitment to engineering excellence in industries where reliability and safety can’t be compromised.
