Wilo-Drain TMT Submersible Drainage Pump for Wastewater with High Temperature Resistance and Temperature Monitoring
Your advantages Temperature resistance for fluid temperatures up to 95 °C High operational reliability due to motor temperature monitoring and sealed cable inlet
Design Submersible drainage pump Application Pumping of Wastewater with a maximum fluid temperature of 95 °C Equipment/function Connection cable for fluids up to 95 °C, permanently connected Winding temperature monitoring with bimetallic strip
Typekey Technical data Mains connection: 3~400 V, 50 Hz Protection class: IP68 Max. immersion depth: 7 m Fluid temperature: Immersed: 3 … 95 °C Non-immersed: 3 ... 60 °C Cable length: 10 m Pressure port: G 1¼ Materials Pump housing: EN-GJL-250 Impeller: EN-GJL-250 Shaft: 1.4021 Mechanical seal: SiC/SiC; Cr/MgSi Static gaskets: HNBR Motor housing: EN-GJL-250
Construction
Fully submersible drainage pump for vertical wet well installation to pump fluids with temperatures of up to max. 95°C.
Hydraulics
The hydraulics housing and the impeller are made of cast iron. The connection on the pressure side is designed as horizontal threaded flange connection.
Motor
Three-phase current surface-cooled motors for direct starting are used as the motors. The waste heat is given off directly to the surrounding fluid via the motor housing. These motors can be operated immersed in continuous duty (S1) and non-immersed in intermittent operation (S3).
Furthermore the motors are equipped with the following monitoring devices:
-
Leakage detection motor compartment: The leakage detection signals water ingress into the motor compartment.
-
Thermal motor monitoring: The thermal motor monitoring protects the motor windings against overheating. Bimetallic strips are used for this as standard.
The connection cable has bare cable ends and a length of 10 m as standard, and is available in following versions: Seal The fluid-side and motor-side seal is provided by two mechanical seals. The sealing chamber between the mechanical seals is filled with medical white oil. Scope of delivery Submersible drainage pump Installation and operating instructions
