TUSSU®WTUsubmersible sewage pump is engineered specifically to tackle these harsh environments, delivering high-efficiency fluid handling for municipal, industrial, and civil construction projects.
Whether you are upgrading a municipal wastewater treatment plant (WWTP) or sourcing reliable dewatering pumps for an aggressive industrial effluent application, understanding the engineering advantages of the WTU and AS-WTU series ensures optimal system performance.
Technical Specifications: Engineered for Performance
The standard WTU submersible pump line covers a massive performance spectrum to meet diverse flow and head requirements:
-
Discharge Diameter: Available from compact 25 mm (1 inch) models up to massive 600 mm (24 inches) industrial discharge ports.
-
Motor Power Options: Spans from light-duty 0.75 kW commercial units up to high-capacity 132 kW engineering-grade motors.
-
Operational Speeds: Configured in 2900 r/min for high-head scenarios, or 1450 r/min and 980 r/min low-RPM setups to reduce wear when handling abrasive sludge.
-
Power Supply: Built standard for 380V / 50Hz (three-phase) infrastructure, with custom global voltages (415V, 440V, 460V) available upon request.
Standard WTU vs. AS-WTU Cutter Pump: Choosing the Right Impeller
Selecting the right pump depends entirely on the solid-handling requirements of your wastewater matrix.
1. Standard WTU Submersible Pump (Non-Clog Channel Impeller)
The standard WQ series utilizes an enclosed or semi-open dual-channel impeller. It is designed for high-flow efficiency and is ideal for moving large volumes of liquid containing suspended solids, greywater, and pre-screened municipal sludge without binding.
2.AS-WTU Shredder Pump (Heavy-Duty Cutting Mechanism)
For fluids laden with stringy materials, rags, or plastics, the AS-WTU cutting-type submersible sewage pump is mandatory. This version is fitted with an integrated dual-blade tungsten carbide cutting mechanism. It actively shreds long fibers, textiles, and organic debris into micro-particles before they enter the pump casing, completely eliminating the risk of pipeline clogging.
Heavy-Duty Applications Across Key Industries
Thanks to their robust cast iron or optional stainless steel construction, WTU pumps operate continuously in the most demanding sectors:
-
Municipal Wastewater Treatment: Ideal for main lifting stations, return activated sludge (RAS) loops, and storm water management.
-
Industrial Effluent Handling: Reliably transfers corrosive factory drainage, paper mill waste, and textile plant discharge.
-
Construction & Mine Dewatering: Pumps out muddy water, gravel-laden silt, and foundation pits on civil engineering sites.
-
Commercial Building Drainage: Provides automatic sewage lifting from basements in high-rise buildings, hospitals, and shopping complexes.
Advanced Protection Features for Maximum Lifespan
Unplanned downtime in a wet well is costly and hazardous. WTU submersible pumps include three critical engineering safeguards to extend service life:
-
Dual Mechanical Seals in Tandem: Faced with silicon carbide-to-silicon carbide surfaces, these seals form an impervious barrier, protecting the motor chamber from fluid ingress.
-
Integrated Moisture & Leakage Probes: Built-in sensors detect early mechanical seal wear, alerting operators before water can breach the motor windings.
-
Thermal Overload Protection: Stator windings feature embedded thermal switches that automatically shut down the pump in the event of overheating, preventing catastrophic motor burnout.
Optimize Operations with the GAK Auto-Coupling System
Entering a hazardous sewage pit for maintenance is a safety liability. The WTU series fully integrates with a Guide Rail Auto-Coupling System (GAK).
With this setup, the pump is lowered down parallel guide rails and automatically hooks into the discharge piping at the bottom via its own weight. For maintenance or inspection, simply lift the pump out using a lifting chain. The pump disconnects automatically—meaning your technical team never has to step foot inside the wet well.
