AX Series – Explosion-Proof Submersible Slurry Pumps for Hazardous & Abrasive Applications
AX submersible pumps are designed for safe and reliable operation in hazardous zones such as mine dewatering, oil & gas exploration, refinery plants, and slurry pits where explosive gases or ignitable atmospheres may exist. With a top discharge for effective motor cooling and a built-in agitator to keep solids suspended, AX pumps are ideal for continuous-duty performance in extreme environments.
