Are sanitary type single screw pumps available for food industry?

Yes, we supply sanitary single screw pump with SS304/SS316L wetted parts, perfectly applied for conveying jam, cream and other food raw materials.

What is the working pressure range of your high viscosity screw pump?

The working pressure of our progressive cavity pump ranges from 0.3MPa to 2.4MPa, meeting the pressure requirements of on-site sludge transportation and PAM dosing system.

Can you customize parameters for the single screw pump?

Customized flow rate, pressure, connection method and installation size are acceptable to match various actual working conditions for industrial and food delivery projects.

What connection methods are used for the inlet and outlet of screw pumps?

Two mainstream connection types are optional: flange connection for industrial sludge pump, and sanitary clamp connection for food-grade single screw pump.

What is the calibration accuracy of your dosing single screw pump?

The volumetric progressive cavity pump owns stable metering accuracy within tolerance 2%~5%, ideal for quantitative delivery of flocculant and chemical agents in wastewater treatment.

AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier with 3D software design, customization, ODM, SDK, and recent new-product development capabilities. It holds ISO9001:2015, ISO45001:2018, and ISO14001 certifications, and has documented procedures for corrective actions and customer complaints. However, evidence indicates limited operational scale: one production line, one quality inspector, one year of export experience, no inventory, no overseas warehouse, no overseas agents or branches, and no valid manufacturing-capacity contract with affiliated subcontractors. Financial results include a stated operating loss, but monetary figures are omitted here. Customer cases and named reference customers are not provided.

Supplier typeThe supplier is explicitly described as a professional technical supplier. Its stated business scope covers mechanical and electrical equipment, industrial control systems, electrical instruments, electronic products, chemical products subject to applicable exclusions, solid waste treatment, and rolling processing.

CertificationsThe supplier reports holding ISO9001:2015, ISO45001:2018, and ISO14001 certifications. These stated certifications provide explicit evidence of quality, occupational health and safety, and environmental management certification.

After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions and customer complaints, supporting structured service handling. However, it reports no inventory, overseas warehouse, overseas showroom, overseas agents or branches, and no participation in offline trade shows, indicating limited overseas service infrastructure.

Financial creditFinancial information is reported for the last two years, but the latest stated operating profit is negative. This is explicit evidence of profitability weakness, while the available slices do not establish broader financial stability or creditworthiness.

R&D capabilityThe supplier reports 3D software design services, SDK availability, ODM services, and new products developed during the past year. These capabilities explicitly support product development and technical innovation, although the supplier does not provide OEM services for popular brands.

Production capacityThe supplier reports one production line and one quality assurance or quality control inspector, with finished products checked by packing staff. It also lacks inventory capacity and has no valid manufacturing-capacity contract with affiliated subcontractors, indicating limited and potentially less resilient production capacity.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. The same range is reported in both technical design and design-services information, providing strong evidence of broad customization coverage.

Product Q&A

Q:What media can a single screw pump transport?

Our single screw pump (progressive cavity pump) is suitable for high viscosity slurry, sludge, PAM flocculant, sewage additives, as well as food sauce, paste and other viscous materials, with good non-blocking performance.

Q:Does your progressive cavity pump have leakage problems?

The single screw pump is equipped with reliable packing seal or mechanical seal structure, which effectively realizes no leakage during long-term continuous transportation of sludge and chemical dosing media.

Q:What kinds of motors are matched for your screw pumps?

We support standard asynchronous motor, variable frequency motor and explosion-proof motor to satisfy different working conditions of sewage treatment and food production workshops.

Q:Why is the single screw pump low pulsation in delivery flow?

Cooperated with precision helical rotor and wear-resistant rubber stator, our progressive cavity pump features stable volumetric conveying and low flow pulsation without damaging food material properties.

Q:Can your sludge screw pump run for a long time continuously?

With wearable rotor & anti-corrosion stator and optimized bearing assembly, the sludge delivery single screw pump supports 24-hour continuous operation with low maintenance cost.
