Hydroman® Heavy Duty Submersible Sump Pump with Internal Cooling is designed for continuous operation in demanding drainage, sewage, and slurry handling applications where high ambient temperatures, partial submergence, or dry-pit conditions are common. Equipped with a sealed internal cooling system, hydroman® submersible sewage pump can operate even when partially submerged, or in dry-pit and semi-dry environments, ensuring motor thermal balance without relying on surrounding fluid.
The internal cooling system typically circulates water or cooling oil around the stator housing, dissipating heat via an independent circuit. This design is essential for installations where liquid levels are unstable, such as construction dewatering, sewage sump pits, wastewater lift stations, and industrial processing tanks.
• Internal Cooling System: Ensures motor cooling during dry or low-water-level operation.
• Non-Clog Impeller: Vortex or semi-open design allows solids and fibrous waste to pass without clogging.
• Double Mechanical Seals: Oil chamber-separated seals prevent leakage and extend life in abrasive media.
• Heavy-Duty Construction: Rugged cast iron, stainless steel, or duplex body for corrosion and impact resistance.
• Optional Explosion-Proof Design: Available for hazardous environments.
• IP68 Protection: Fully sealed submersible motor with thermal overload protection.
