Propeller Pumps is one of the leading manufacturers, exporters and suppliers of Solid Liquid Separator Machines (SLS) in India and is exporting worldwide including UAE, Saudi Arabia, Singapore, Indonesia, Philippines, Egypt, Ethiopia, Nigeria, Kenya, Russia, Uzbekistan, Kazakhstan and across the globe. Our SLS machines are engineered for continuous operation, wide material compatibility, and fast return on investment.
What Is a Solid Liquid Separator Machine?
A Solid Liquid Separator Machine is a mechanically driven separation device designed to process mixed streams where separation of the solid and liquid phases is required for further downstream handling. The machine is composed of four principal assemblies: a feed device, a separator casing incorporating a screw conveyor and cylindrical screen, a compacted solid material outlet module, and one or two separated liquid outlets. A drive unit and structural basement frame complete the machine assembly.
The feed device takes the form of either a feeding hopper or a compensator tank depending on whether the incoming material is conveyed mechanically or pumped into the separator. This flexibility in feed arrangement allows the SLS machine to be integrated into existing process lines regardless of how the upstream material is transported.
The separated solid and liquid phases produced by the machine can each be handled in a simpler and more cost effective manner than the original mixed stream, reducing the burden on downstream storage, transport, and disposal or reuse operations.
Solid Liquid Separator Machine (SLS) Design Features
Propeller Pumps Solid Liquid Separator Machines are engineered for reliable, low maintenance continuous operation with strong process performance across a wide range of feed materials:
- Compliance with a wide range of materials and throughput capacities, from low-volume batch applications to high-capacity continuous processing.
- Optimised feeding tanks and compensator tank configuration ensure steady and controlled material supply to the screw conveyor.
- Outlet diaphragm for the compacted solid is manufactured from anti-wear engineering polymer, reducing spare parts costs and extending service life.
- Self-balanced pressure at the solid outlet ensures steady and safe operation without manual adjustment during continuous running.
- Self-cleaning cylindrical screen maintains long service life and sustained separation performance over extended operational periods.
- Modular screw manufactured from anti-wear engineering polymer allows simple component replacement and reduces spare parts expenditure.
- Continuous operation capability supports integration into 24-hour process lines without the downtime associated with batch separation equipment.
- Quick return on investment through reduced handling costs, lower disposal volumes, and recovery of the separated liquid phase for reuse or treatment.
