1 Series description Wilo-Drain STS 40 Series description Wilo-Drain STS 40 Subject to change 09/2008 WILO SE Wilo Catalogue C2 - - Sewage pumps from DN 32 to DN 800 Materials Pump housing: EN-GJL-250 Pedestal: Cast iron Impeller: Stainless steel Shaft: Stainless steel Mechanical seal on pump side: Shaft seal on motor side: NBR Static seal: NBR Motor housing: Stainless steel Description/design Submersible sewage pump as submersible monobloc unit for stationary and portable wet well installation. Design Submersible sewage pump Type key e.g.: STS Wilo-Drain STS 40/10-A Submersible pump 40 Nominal diameter [mm] 10 Max. delivery head [m] A With float switch Application Pumping of heavily contaminated fluids for: House and site drainage Sewage disposal (the pumping of sewage containing faeces is not within the scope of DIN EN ) Water management Environmental and water treatment technology Industrial and process engineering Special features/product advantages Detachable connection cable and float switch Dry motor, stainless steel version Attached float switch (A-model version) enables simple operation Integrated pump base for easy installation Free ball passage: 40 mm No switchgear required for thermal fuse protection Integrated thermal motor protection (1~/3~) and phase failure protection (3~) Technical data Mains connection: or Immersed operating mode: or S3 25% Protection class: IP 68 Insulation class: B Thermal winding monitoring Max. fluid temperature: 3-35 C Cable length: 10 m Free ball passage: 40 mm Max. immersion depth: 5 m Equipment/function Ready-to-plug single-phase version A-model version including float switch Thermal motor monitoring Hydraulics The outlet on the pressure side is designed as vertical threaded connection, Rp 1½. Vortex impeller are used as the impeller shapes. Motor Dry motors give off their heat directly to the surrounding fluid via the housing components and can be used in immersed state for permanent or intermittent operation. A sealing chamber protects the motor from fluid ingress. The filling fluid used is biodegradable and environmentally safe. The single-phase motors are equipped with shock-proof plugs, and A-model versions with float switches. The three-phase motors are equipped with bare cable ends. Sealing Sealing on the fluid side is achieved by a bidirectional mechanical seal, while sealing on the motor side is achieved by a rotary shaft seal. Scope of delivery Pump ready for connection with 10 m connection cable - For 1~230 V with shock-proof plug - For 3~400 V with bare cable end A-model version with attached float switch Installation and operating instructions Accessories Non-return valve and gate valve Various pressure outlets and hoses Switchgears and relays Wilo Catalogue C2 - - Sewage pumps from DN 32 to DN
