Sewagecontaining mineral oils or explosive admixtures must be guidedthrough oil precipitators and/or petrol precipitators; those containingfatty substances must go through grease traps and those with sandthrough grit chambers.Special features/product advantages• High efficiency, due to pumps with small free ball passage• Large delivery heads• System non-susceptible to clogging, due to solids separation• Large tank volumeTechnical data• Mains connection 3~400 V, 50 Hz• Mains connection cable (pumps) 10 m,• Operating mode: S2-10 min (STS 65), S2-15 min (FA08.43E)• Fluid temperature max. 40 °C• Ambient temperature max. 40 °C• Free ball passage 65 mm (STS 65), 70 mm (FA08.43E)• Pressure port DN 100• Inlet connection DN 150• Ventilation DN 100• Min. suction head (up to bottom edge of inlet) 750 mm• Protection class (without switchgear) IP 68• Gross tank volume 400 l• Switching volume 300 lMaterials• Motor housing: stainless steel 1.4404 / AISI 316L (STS 65), cast ironEN-GJL-250 (FA08.43E)• Hydraulics: Grey cast iron EN-GJL-250• Tank: PE plasticEquipment/function• Thermal motor monitoring• Level control with level sensor• Potential-free contact• Non-return valve• Inlet seal• Fixation materialDescription/designFully submersible, connection-ready sewage lifting unit with integratedsolids separation system. Equipped as double-pump systemwith two Wilo-Drain STS 65 or FA08.43E pumps.Due to the use of solids separation tanks, the pumps do not come intocontact with the solids. In this way, pumps with optimised efficiencycan be used for pumping sewage.The dry well installation of the pump and its configuration as redundantdouble-pump system ensures maximum ease of maintenanceand operational reliability. The complete system, apart from thepumps and non-return valve, is made of corrosion-resistant PE-HD.Fully submersible compact unit ready for connection with a gastightand watertight collection tank.Easy handling and optimum tank drainage by means of deep extractionby suction.Attention: The switchgear is not submersible and must therefore bearranged in such a way that it is safe from flooding.Scope of deliverySewage lifting unit ready for connection with solids separation systemincl. pumps, switchgear, non-return valve and Y-piece.Optional, individual blocking of the solids separation reservoir.Wilo Water Management catalogue – 50 Hz – Drainage and Sewage – Waste water collection and transport – Edition 2012/2013 – Subject to change without prior notice35
