Sewage/FaecesWilo-Drain TP 40 S/25, TP 40 SProduct DescriptionWilo-Drain TP 40 S/25, TP 40 SSubmersible sewage pump with macerator, 2-poleType keyExample: Wilo-Drain TP 40 S 25TP Submersible pump40 Nominal diameter [mm]S Impeller type S = Macerator25 Max. delivery head [m]ApplicationsWilo-Drain TP 40 S submersible sewage pumps with macerator areideal for conveying household sewage including faeces. The Wilomacerator disintegrates the solid contents to particle sizes smallenough to pass through the pump impeller. Preferred application isthe pressurised waste disposal which is applied in such cases wherecosts for the conventional gravity sewage displacement becomeunjustifiably high, such as the following situations:– high ground water levels– insufficient ground gradients– intermittent generation of sewage– holiday home, camping grounds etc.Because of the low line diameter, e.g. DN 40, the installation costsare reduced dramatically.Suitable for:– Stationary wet sump installation– PortableDesignMonobloc submersible sewage pump with macerator for vertical wetsump installation.– Novel patented macerator– Free flow to the impeller– Inside rotating cutting– Conically designed macerator– Disintegrating particles– Drawing cutting actionMotorThree-phase asynchronous motor 3~400 V, 50 Hz or AC motor1~230 V, 50 Hz each with protection class IP 68, protected by thermalwinding contacts, insulation class F. Stainless steel motor designfor TP 40 S/25.BearingsThe motor shaft is bedded in permanently lubricated roller bearings.Shaft sealTP 40 S:Mechanical seal bidirectional and shaft seal on the pump side andmotor side. Oil-filled intermediate chamber for cooling and lubrication.TP 40 S/25:Bidirectional mechanical seal on the motor side, shaft seal on thepump side. Oil-filled intermediate chamber for cooling and lubrication.Hydraulic dataClosed single-vane impeller (with a free ball passage of 10 mm) inconjunction with a patented macerator ensures non-clogging pumpingand maximum efficiency.Scope of deliveryFully assembled pump with 10 m power cable and bare cable end at3~400 V; 10 m power cable and switch box (terminal strip) at1~230 V.Sewage/FaecesWilo-Drain TP 40 S/25, TP 40 SProduct DescriptionSubmersible pumpsAs of: 06/2004 - Subject to change without prior notice53
