Polymer / PAC Flocculant Dosing System for Water Treatment Projects
Candidate sourcing page for a skid-mounted polymer preparation and dosing system used with PAC or polymer flocculants in wastewater and water treatment applications. This is equipment, not a PAC chemical supply listing. Buyer checks should focus on dosing capacity, wetted-part materials, pump inclusion, electrical configuration, corrosion resistance, export packing, HS code, inspection documents, and compatibility with the intended PAC grade or polymer solution concentration.

Before matching
Documents to check
CAS number, grade, assay, and impurity profile
SDS, COA, TDS, HS code, and transport classification
Destination-market import documents before supplier matching
Package and route
Packing notes
Export package stated as anticorrosion wooden case with foam inside
Confirm whether wood packaging is fumigated or ISPM 15 compliant for destination customs
Request packing dimensions, gross weight, lifting points, and container loading plan before RFQ confirmation
Confirm whether sensitive electrical components, pumps, control panels, and spare parts are packed separately or protected for sea freight
Clarify whether packaging is suitable for long-distance ocean shipment, inland transport, and humid storage conditions
Applications and sourcing options
Check whether this product fits the buyer's actual application.
Clear application, grade, package, and document notes help separate real sourcing demand from a vague price check.

Human review
Compliance notes
This listing is for dosing equipment, not PAC chemical material; CAS number and chemical assay checks apply to the PAC/flocculant purchased separately
For equipment export, verify HS code, CE/ISO/SGS document scope, factory inspection record, commercial invoice, packing list, and country-specific import requirements
Request material certificates for wetted parts if dosing PAC, PAM, or other corrosive/coagulant solutions
Confirm whether the unit contains pumps, control cabinet, sensors, electrical components, or spare chemicals that may affect customs classification or documentation
PAC and polymer chemicals may have separate SDS, DG/non-DG classification, impurity, concentration, and heavy metal requirements; do not assume equipment supplier documents cover the chemical reagent
Ask for destination-specific export documentation availability without relying on supplier claims as regulatory guarantees
Confirm voltage, frequency, plug/control standards, and motor protection compatibility with the buyer’s installation country
If chemicals are shipped together with equipment, request separate SDS, COA, DG transport classification, and packing details for each chemical item

Questions to confirm
Is the offer for the dosing system only, or does it include PAC, polymer powder/liquid, metering pump, control cabinet, instruments, and spare parts?
What is the required PAC or polymer solution concentration, and what dosing range in L/h or m3/h should the system support?
What are the tank volume, number of chambers, mixer power, residence time, and continuous preparation capacity?
Which wetted-part materials are used for tank, mixer shaft, impeller, pipes, valves, seals, and pump head?
Is the metering pump included despite the basic information stating dosing pump not included? If included, what brand, model, flow rate, pressure, and material?
Can the system handle the buyer’s PAC specification, pH range, chloride level, viscosity, and suspended solids without excessive corrosion or clogging?
What electrical supply is required, and can the panel be supplied for the destination voltage, frequency, enclosure rating, and language labeling?
What documents are available before shipment: product drawing, GA drawing, P&ID, wiring diagram, inspection report, CE declaration, ISO certificate, packing list, and HS code confirmation?
