Product Description
The piston forwarder (usually a piston pump) delivers the thoroughly blended slurry from the mixer through an enclosed high-pressure piping system into a rotary kiln or a cement calcinator for final thermal disposal.
?
1. Piston-type waste transfer pumps support continuous delivery of blended slurry through fully enclosed pipelines at pressures up to 2.5 MPa, ensuring leak-free, odor-controlled transport. Typical flow rates range from 5 to 60 m3/h, depending on material properties and configuration. Capable of handling solid content up to 20%, the system maintains reliable throughput even with fibrous or abrasive components.
2. Key components—including wear plates, pistons, and cylinder liners—are manufactured from high-chrome alloy steel or ceramic-reinforced composites, extending service life to over 15,000 operational hours under normal sludge conditions. Seals and valves are designed for low maintenance frequency, with average overhaul intervals exceeding 12 months in continuous-use applications.
3. Available in horizontal or vertical layouts, with customizable hopper volumes (0.5 to 3 m3) and outlet pipe diameters (DN100–DN250), the system accommodates a broad range of feed materials—from dewatered municipal sludge to industrial slurry and RDF (Refuse Derived Fuel). Optional automation integration (PLC/SCADA compatible) supports fully synchronized plant operations.
4. All systems comply with CE and ISO 45001 safety standards. Overpressure protection, automatic shut-off, and enclosed transfer design reduce operator risk and ensure alignment with environmental regulations, including EU Emissions Directive (IED) and local waste transport guidelines.

Note: The above data are standard configurations for typical models and?can’t be taken as the only principle for type / model selection, such facts as the viscosity / liquid ratio of the mixture and the needed distance of delivery should also be taken into consideration, actual data are subject to adjustment according to specific requirements. More models and configurations are for inquiry and for face-to-face discussion.

Municipal Waste Treatment
Transfers digested or dewatered sludge (typically DS 12–18%) over long distances (up to 200 meters) with minimal clogging. Supports continuous operation in anaerobic digestion and sludge drying lines at urban wastewater treatment facilities.
Industrial Waste Processing
Handles chemically aggressive or abrasive slurries such as paint sludge, chemical waste residues, and metal-bearing sludge with solid particles ≤30 mm. Ensures smooth material flow with inlet pressure buffering and anti-wear lining, reducing system downtime.
Energy Production
Feeds homogenized waste (e.g., sludge mixed with RDF or biomass) into thermal energy systems such as rotary kilns or fluidized bed incinerators. Maintains stable dosing rates between 1–5 tons/hour, supporting consistent combustion and emission control.
