November 12, 2025 - Finish Thompson Inc. (FTI), an international leader in the corrosive chemical transfer industry, has announced the launch of its SX Series explosion-proof electric motor for drum and barrel pump applications. Designed for global use, the SX Series represents a significant advancement as an economical, electrically powered explosion-proof and flame-proof motor.

Constructed for the EFS Series drum pump/container pumps, these motors support the rigorous demands of hazardous fluid handling environments. The new SX Series is engineered to meet the highest standards of performance, safety, and reliability, making it ideal for transferring flammable and combustible fluids as well as applications in hazardous locations.

The SX Series is engineered with a powerful two-speed motor, delivering up to 17 gallons per minute (64.4 lpm) at full speed and 7 gallons per minute (26.5 lpm) at low speed for non-flammable fluids, and up to 4 gallons per minute (15.1 lpm) for flammable or combustible liquids. The motor can empty a full 55-gallon drum (≈200 liters) in just over three minutes, while the lower speed enables precise filling of smaller containers with minimal splashing.

Weighing just 6.6 pounds, the SX motor is built for lightweight handling, yet is robust enough for continuous use and to empty multiple containers in succession without overheating or performance loss. A key safety feature is the built-in grounding lug, enabling the motor, pump tube, and container to be bonded and grounded together to dissipate any possible accumulations of static electricity.

Finish Thompson offers the SX Series in three distinct versions for worldwide operation. The S1X model, rated at 115 volts, is explosion-proof and flame-proof, QPS certified for Class 1, Division 1, Group D environments with a T3 temperature rating, and is suitable for ambient temperatures from -4°F to 104°F. The S2X model, rated at 230 volts, is certified for international standards including CE, ATEX, and ICEx for II 2G Ex db IIB T5 Gb environments, supporting temperatures from -4°F to 104°F. For high-temperature applications, the S3X-HT provides enhanced performance in environments up to 140°F, incorporating the same robust certifications to meet the needs of the most challenging applications. All models feature a 12-foot cord for flexible installation and easier access to power sources.
