Submersible Sump Pump Float Switch Screw Centrifugal Pumps

General DescriptionThe spiral-centrifugal pump can go beyond the limits of classical centrifugal pumps, and even into the application area of positive displacement pumps. The construction is suitable for the handling of solids in suspension and viscous liquids, as well as for applications with larger negative suction heads.The shape of the inlet edge creates an "inducer effect", which makes a large negative suction head possible (or a higher transportation media temperature). A pronounced screw shape creates a displacement effect with high viscosities, which makes possible the handling of viscous liquids well into the displacement pump application range.Design Features> Non-blocking> High suction head> Low shear force, soft conveying> High efficiency> Stable and steep curve> Long service life> Low disturbance> Flow proportional to the speed> Stable operation in a wide speedOperation ConditionsFluid: Raw sewage and industrial wastewater without grid filtration, long fiber, transporting activated sludge without damaging biological bacteria, transport sludge with a solid content of up to 18%.> Working Temperature Range:  -10ºC ~ 80ºC.   When working temperature exceeds 80ºC,shall clarify clearly and in advance.> Operating pressure: PN1.0 MPa - Hydrostatic test pressure = PN1.6MPaPN1.6 MPa - Hydrostatic test pressure = PN2.4MPa (optional)Specifications> Pump suction flange (mm): DN50 to DN500> Pump discharge flange (mm): DN50 to DN500> Capacity Q: 7 to 5040 m3/h> Head H: 0.5 to 100 m> Liquid temperature: -10ºC up to +80ºC> Speed: 50Hz or 60Hz, Variable frequency operation / VFD.> Wide hydraulic coverage> Low NPSH requirementMaterials of Construction (Main parts)Part DescriptionMaterial / Main partsSuction casingCast Iron / Ductile Iron / Stainless Steel / Duplex SSSuction bushingCast Iron / Ductile Iron / Stainless Steel / Duplex SSlinerCast Iron / Ductile Iron / Stainless Steel / Duplex SSScrew-centrifugal impellerCast Iron / Ductile Iron / Stainless Steel / Duplex SSPump casingCast Iron / Ductile Iron / Stainless Steel / Duplex SSPump coverCast Iron / Ductile Iron / Stainless Steel / Duplex SSShaftCarbon steel / Stainless Steel / Duplex SSMotor housingCast Iron / Stainless Steel / Duplex SSCable coverCast Iron / Stainless Steel / Duplex SSBearingsFAGs / SKFs / NSKMechanical sealPump end: SSiC / SSiC / Viotn / SS316Motor end: SSiC / SSiC / Viotn / SS316ApplicationSewage field:> Raw sewage and industrial wastewater without grid filtration, long fibers.> Transporting activated sludge without damaging biological bacteria, transport sludge with a solid content of up to 18%.Chemical industry:> Conveying chemical pulp containing particles.> Transporting oil water mixtures to transport chemicals with a viscosity of up to 4000 cSt has a much lower correction factor than other centrifugal pumps.Pulp and Paper Industry:> Flexible conveying of pulp containing fibers.> Conveying long paper fibersSelection Charts  Company Profile COMPANY INTRODUCTIONDongguan Hydroblue Tech Co.Ltd, setup in 2007, is known as a fast-growing provider for pumps, motors, sealing systems, couplings, gearboxes and engineering solutions.
