The Wilo maceratorbreaks down the solid constituents into smaller pieces to generate aneasily pumpable fluid. Preferred utilisation with pressurised drainage.The pressurised drainage is utilised in situations where the costs of aconventional sewage system with an open channel would be unacceptablyhigh, e.g. with:- high groundwater table levels- absence of ground incline- occasional presence of sewage- vacation house, camping site, among others.- Installation costs are decidedly lower because of the small pipelinediameter, e.g. DN 40,Can be utilised in the following installation types-stationary wet-portableConstructionSubmersible sewage pump as submersible monobloc unit withmacerator for vertical wet installation- innovative patented macerator- unimpeded supply line to the impeller- internal rotating blade-spherically formed macerator- maceration of substances being conveyed- pulling cut (shearing cut)MotorThree-phase current asynchronous motor made of stainless steel3~400 V, 50 Hz or alternating current motor made of stainless steel1~230 V, 50 Hz each of protection class IP 68, protected by thermalwinding contacts, insulation class F.Bearing configurationBearing configuration of the motor shaft in permanently lubricatedroller bearings.Radial shaft sealing ringMTS 40/...:Direction of rotation-independent mechanical seal on pump side,shaft seal ring on the motor end. Oil-filled intermediate chamberprovides cooling and lubrication, even with dry run.MTS 40 E:Direction of rotation-independent mechanical seal on the pump andmotor sides. Oil-filled intermediate chamber provides cooling andlubrication, even with dry run.HydraulicsClosed single channel wheel (with a free ball passage of 10mm) inconjunction with the patented macerator make possible blockagefreepumping and optimal efficiency.Scope of deliveryPump ready for connection with 10 m connection cable,at 3~400 V: with bare cable end,at 1~230 V: with capacitor connection box and shock-proof plug.Submersible Motor Pumpswith MaceratorSubmersible Motor Pumpswithout MaceratorElectrical AccessoriesWilo-DrainFlag4Flag5Wilo Catalogue C2 – 50 Hz – Sewage Pumps DN 32 to DN 60027
