Submersible Sewage Pump for Municipal & Industrial Wastewater
Raw sewage, sludge, and solids-laden wastewater demand a pump that keeps running without blockages or motor failure. The submersible sewage pump Model DL from Tsurumi pumps combines a non-clog channel impeller, dual silicon carbide mechanical seals, and an oil-cooled motor built for continuous-duty municipal and industrial operations.
This submersible sewage pump handles solids up to 88mm, ideal for hospitals, industries, and municipalities, ensuring clog-free wastewater pumping. We supply the Tsurumi submersible pump Model DL as a reliable sewage wastewater treatment pump across pump stations, treatment plants, and flood control infrastructure throughout the UAE and GCC.
At Dutco Tennant LLC, we are trusted tsurumi pump distributors supplying municipal sewage pumps and industrial submersible pumps to wastewater authorities, MEP contractors, and facility operators across the UAE and GCC.
Why the Model DL Keeps Running
- Submersible wastewater pump non-clog channel impeller passes solids and fibrous matter without wrapping or blocking during continuous operation.
- Dual silicon carbide mechanical seals run in a separate oil-filled chamber, isolating the motor from pumped fluid at all times.
- Oil Lifter mechanism maintains seal lubrication down to one-third of normal oil level during low-level pumping conditions.
- Cast iron construction with epoxy coating suits chemically aggressive and abrasive wastewater pumps applications.
- Anti-wicking cable prevents water ingress into the motor along the power cable in fully submerged installations.
Core Capabilities at a Glance
- Non-Clog Channel Impeller: Maximises solid passage in raw sewage, fibrous material, and solids-laden waste water pump system applications.
- Dual Silicon Carbide Mechanical Seals: Independent oil chamber protects the motor, extending operational reliability across continuous-duty sewage pumps installations.
- Thermal Overload Protection: Built-in stator sensors trigger automatic shutdown before motor winding temperatures reach damaging levels.
- Oil Lifter System: Tsurumi-patented mechanism maintains seal lubrication at reduced oil levels without consuming additional power.
- IP68 Rated Motor: Fully sealed construction allows continuous submersion as a vertical submersible pump in permanent wet well installations.

FAQ
What motor protection does the Model DL have?
The motor features built-in thermal overload sensors and an IP68-rated sealed construction, protecting against overheating and continuous submersion in permanent wet well installations.
What power supply options are available for the Model DL?
The Tsurumi submersible pump Model DL is available in single-phase and three-phase configurations, covering both residential and commercial site power supply requirements.
Can the Model DL operate in an automatic pump station?
Yes. The pump is compatible with float switches, level sensors, and automated control panels, allowing fully unattended operation in municipal and industrial pump stations.
Is the Model DL suitable as a septic tank pump?
Yes. The non-clog impeller and solids handling capability make the septic tank pump configuration suitable for transferring raw septic contents and primary settled sewage in on-site wastewater systems.
How is the Model DL installed in a wet well?
The best submersible water pump guide rail system allows the unit to be lowered and raised by lifting chain without personnel entering the wet well, supporting safe maintenance access.
What makes the Model DL suitable for the UAE climate?
Epoxy-coated cast iron construction and sealed IP68 motor maintain reliable performance in the high-temperature and high-humidity conditions common across submersible sewage pump UAE installations.
