⚠️ Reliable Motors for Demanding Industrial Applications

Square One Electric Motors & Pumps offers a wide selection of severe duty motors and hazardous location motors designed for the most challenging and high-risk environments. These motors are engineered to withstand extreme heat, moisture, chemical exposure, abrasive dust, and potentially explosive atmospheres — without compromising performance or safety.

Whether you're operating in an oil refinery, chemical plant, food processing facility, wastewater treatment plant, or paper mill, we have the industrial-grade motors you need to maintain uptime, safety, and compliance.

🔥 What Are Severe Duty and Hazardous Location Motors?

These are specialty electric motors built to meet rigorous application demands beyond standard operating environments.

  • Severe Duty Motors: Built to operate in dirty, moist, or corrosive environments such as paper mills, chemical processing, or outdoor industrial settings.

  • Explosion Proof Motors: UL and CSA listed for use in Class I & II Division 1 hazardous environments (flammable gases, vapors, dust).

  • IEEE 841 Chemical Duty Motors: Designed for petrochemical and chemical plants with additional protection against harsh chemicals, extended lifespan, and enhanced corrosion resistance.

⚙️ Types of Severe Duty & Hazardous Location Motors
