1 Series description Wilo-Drain TP 80/TP 100 Equipment/function Thermal motor monitoring Leakage detection in the motor ATEX-certified Sheath current cooling Materials Pump housing: PUR Impeller: PUR Shaft: stainless steel Mechanical seal on pump side: SiC/SiC Mechanical seal on motor side: C/Cr Static gasket: NBR Motor housing: stainless steel Design Submersible sewage pump for industrial applications Type key e.g. Wilo-Drain TP 80 E 160/17 TP Submersible pump 80 Nominal diameter [mm] E Single-channel impeller 160 Nominal diameter of the impeller [mm] 17 Power P 2 [kw] (=value/10 = 1.7 kw) Application Pumping of wastewater and drainage water as well as sewage containing faeces, municipal and industrial sewage for: domestic and site drainage sewage and water management Environmental and water treatment technology Industrial and process engineering Special features/product benefits Operation in stationary wet well and dry well installation as well as portable wet well installation Submersible ATEX approval as standard Low weight Detachable connection cable Longitudinally watertight cable inlet Standard-equipped with clogging-free sheath current cooling Corrosion-resistant (e.g. swimming-pool water, salt water, etc.) Low-wearing Patented clogging-free hydraulics Easy installation due to suspension unit or pump base Technical data Mains connection: 3~400 V, 50 Hz Immersed and surfaced operating modes: or S3 25% Protection class: IP 68 Insulation class: F Max. fluid temperature: 3-40 C Free ball passage: 80 or 95 mm Max. immersion depth: 20 m Description/design Submersible sewage pump as submersible monobloc unit for stationary wet well and dry well installation as well as portable wet well installation. Hydraulics The outlet on the pressure side is designed as DN 80 or DN 100 horizontal flange connection. Single-channel impellers are used as the impeller shape. Motor Dry motors are equipped with clogging-free sheath current cooling as standard. This ensures that heat is given off directly to the fluid. As a result, these units can be operated in immersed and non-immersed state for permanent or intermittent operation. In addition, the motor is equipped with a leakage detection unit and a thermal motor monitoring unit. A sealing chamber protects the motor from fluid ingress. The filling fluid used is potentially biodegradable and environmentally safe. The cable inlet is longitudinally watertight, the standard cable length is 10 m. Sealing Sealing on the fluid side and on the pump side is achieved by two bidirectional mechanical seals. Scope of delivery Pump ready for connection with 10 m connection cable (bare cable end) Installation and operating instructions Accessories Suspension unit Chain Non-return valve and gate valve Various pressure outlets and hoses Switchgears and relays Options HD version with Viton seals and another mechanical seals Pumps without cooling jacket for use in higher-viscosity fluids such as sludge (intermittent operation S3-25 only) Salt water version for higher temperatures and salt contents Version for horizontal dry well installation External cooling for fluid with floating solid matter, such as wood chippings Cable lengths up to 50 m are available in length increments of 10 m 180 Wilo Building Services catalogue 50 Hz Drainage and sewage Edition 2011/2012 Subject to change without prior notice
