What is the lead time for production?

Peak season lead time is one month; off-season lead time is within 15 workdays.

What certifications does the machine have?

The machine comes with ISO 9001:2008 certification.

What is the working principle of the volute screw press?

Sludge moves under helical axis pressure through narrowing gaps, squeezing water out between fixed and moving plates while the screw speed remains low (2-4 r/min).

Key features

Clog-Free Self-Cleaning: Helical axis and moving rings detach for continuous self-cleaning, handling fats, oils, and fibers without clogging.

Low Power Consumption: Unit power consumption is only 0.1-0.01kwh/kg-DS, which is 1/8 of belt press and 1/20 of centrifuge.

Fully Automatic Operation: PLC controlled auto system allows 24-hour unmanned operation with safe and simple programming.

No Secondary Pollution: Low speed (2-4 r/min) ensures no vibration, noise, or smell, creating a great working environment.

Stainless Steel Durability: Body made of stainless steel ensures long service time; only screw shaft and moving rings need replacement.

Phosphorus Removal: Aerobic dewatering prevents phosphorus release, enhancing the overall sewage treatment system's removal function.

Lightweight Design: Mechanical dewatering extrusion without rollers reduces body weight and decreases total project investment.

Wide Application Scope: Suitable for municipal, food, leather, pharmaceutical, and oily sludge industries.

AI-Powered supplier vetting

SummaryThe supplier demonstrates manufacturing capabilities across multiple machine types, operates two production lines, maintains in-stock capacity, and reports defined procedures for finished-product inspection, corrective actions, and customer complaints. It offers extensive customization, exports to more than 40 countries, and derives 51%–70% of sales from exports. However, evidence also shows no SDK availability, no valid manufacturing-capacity contract with affiliated subcontractors, no overseas warehouse or showroom, no raw-material traceability, no ongoing batch quantity reconciliation, and no outsourcing SOP. Certification status, customer-specific cases, and several sustainability indicators are not documented. Financial information is represented only by reporting years, which is insufficient to assess financial credibility.

Supplier typeThe supplier is presented as a machinery manufacturer with facilities or equipment covering saw, winding, welding, slotting, drilling, lathe, grinding, and gear-hobbing operations. Its registered business scope is broad and includes industrial, chemical, rubber, tool, electronic, medical-device, furniture, building-material, and trading activities, so the machinery-manufacturing identity is supported by the equipment information but not narrowly defined by the stated business scope.

After-Sales capabilityThe supplier claims good after-sales service and has clear, followed procedures for customer complaints and corrective/preventive actions. However, it has no overseas warehouse or showroom, so the evidence supports structured service handling but not strong overseas service infrastructure.

Production capacityProduction evidence includes two production lines, multiple machine categories, stated output information for filter equipment and sludge dewatering machines, in-stock capacity, and lead times of within 15 workdays off-peak and one month during peak periods. Capacity controls have weaknesses: there is no valid manufacturing-capacity contract with affiliated subcontractors, no ongoing batch quantity reconciliation, and no outsourcing SOP.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, and flexible customization. This is direct evidence of broad customization capability.
