Hydroman® Submersible Sewage Sump Water Pumps with Internal Cooling is specifically designed for handling raw sewage, wastewater, and sludge in deep sump pits or low-liquid-level environments. Unlike standard submersible pumps that require full submersion for effective cooling, this model features a built-in internal cooling system that allows it to operate safely even in partially submerged or dry-running conditions.
Hydroman® submersible sewage pump is an ideal solution for municipal sewage stations, wastewater treatment plants, industrial drainage, and building sump systems, where continuous operation, reliability, and space-saving installation are critical.
• Pump Casing: Rigid cast iron or optional stainless steel; pressure-tested for strength.
• Impeller Type: Semi-open or vortex; non-clogging design enables solid passage up to 75 mm.
• Impeller Material: High-chrome alloy steel (A05), ductile iron, or SS316 for corrosive use.
• Motor Housing: IP68-rated, oil-filled with embedded thermal sensors.
• Cooling Jacket: Integrated internal passage jacket (cast with motor housing).
• Shaft Seal: Dual mechanical seal in separate oil chamber (SiC/SiC, optional TC/TC).
• Discharge Direction: Top vertical (upward) for compact, efficient installation.
• Bearings: Oversized, heavy-duty thrust and radial bearings for extended life.
• Closed-Circuit Coolant Circulation: Utilizes either water or special coolant inside a jacket casing.
• Continuous Motor Cooling: Maintains optimal operating temperature during low-submersion or dry-run.
• Prevents Motor Overload: Avoids overheating in intermittent or irregular water levels.
• Ideal for Sump Pits: Especially effective in applications with inconsistent inflow or shallow basins.
• Guide Rail System with Auto-Coupling: Fast maintenance, ideal for deep municipal pits.
• Free-standing Portable Unit: Base stand, flexible discharge hose, float control (temporary use).
• Fixed Vertical Installation: Compact design for chambers with limited space.
• Municipal Sewage Lift Stations
Designed for deep collection pits, pumping raw sewage.
• Commercial Building Sumps
Handles grey water and black water in underground systems.
• Industrial Wastewater Sumps
For textile, chemical, and process effluents containing solids.
• Infrastructure Drainage
Tunnels, basements, underground parking and underpasses.
• Biological Treatment Plants
Recirculation, return sludge handling in clarifier basins.
