About Shanghai Qilee Environmental Protection Equipment Co., Ltd. - Industrial Water Treatment and Metering Pump Supplier in China

Shanghai Qilee Environmental Protection Equipment Co., Ltd. operates from China and lists 26 active products across its catalogue, concentrated in industrial water treatment hardware and chemical dosing equipment. The range covers RO membrane elements from DuPont Filmtec and Toray lines, screw-type and belt-press sludge dewatering machines, multi-format metering pumps (mechanical diaphragm, electromagnetic, plunger, solenoid-piston, and pneumatic Pulsafeeder-style units), and online process instrumentation including microprocessor pH meters and aquaculture dissolved oxygen probes. Two catalogue items carry explicit HS codes: the microprocessor online pH meter under 9027.20 (chromatographs and electrochemical instruments) and the fish-farm dissolved oxygen meter under 9027.80 (other physical/chemical analysis instruments), both housed in ABS plastic enclosures. The supplier's listed top categories span Industrial Pumps, Water Filters, Water Treatment Plants, Industrial Machinery, Industrial Filters, Electronic Meters, Electric Power Meters, Screws, and Tools & Instruments, reflecting a workshop-to-membrane mix rather than a single-product focus. The company's catalogue sits at the intersection of three equipment families that are commonly bundled in municipal and industrial water projects: separation technology (RO membranes and filter presses), precision dosing (metering pumps across at least eight mechanical variants), and process analytics (pH and DO instrumentation). Reverse osmosis membranes cited include 4040-format Filmtec seawater elements and Toray high-TDS SWRO elements, which are typically specified for feed water above 10,000 ppm TDS. Sludge dewatering lines include screw press, belt press, volute screw press, and mobile continuous filter press formats, indicating coverage of both municipal sewage and on-site industrial slurry applications such as lime dosing. Process meters listed include a microprocessor pH unit (HS 9027.20) and an IP65-rated dissolved oxygen probe for aquaculture (HS 9027.80), giving buyers a partial instrumentation package to pair with the dosing pumps.

Product Range and Specialties of Shanghai Qilee Environmental Protection Equipment Co., Ltd.

The catalogue spans 26 active SKUs built around four practical groupings. First, RO membrane elements for brackish and seawater desalination, including Filmtec and Toray SWRO parts in standard 4040 (4-inch by 40-inch) spiral-wound format, which is the most common industrial element size and typically operates at 600-1,000 psi with 99.5-99.7% nominal salt rejection on seawater feeds. Second, sludge dewatering machinery in screw press, belt press, and mobile continuous configurations, used to reduce sludge cake moisture from roughly 98-99% feed solids to a 20-30% dry solids cake depending on feed type. Third, metering pumps in at least eight drive variants (mechanical diaphragm, electromagnetic, plunger, solenoid-piston, plastic diaphragm, digital polymer, pneumatic micro, and high-pressure electric), covering flow rates typically from under 1 L/h in lab units to several hundred L/h in process units, with pressure ratings commonly from 3 bar on low-pressure plastic diaphragm models up to 200+ bar on plunger-type units. Fourth, online process instrumentation, where the microprocessor pH meter (HS 9027.20, ABS housing) and the IP65 aquaculture dissolved oxygen meter (HS 9027.80) are the two items with declared HS codes. Buyers in this category typically request electrode slope data, reference junction type, and NEMA 4X or IP65 ingress ratings for field installation. Across the full range, common buyer-side specifications to confirm include membrane nominal rejection rate and active area in square feet, dewatering machine dry solids throughput in kg DS/h, metering pump flow/pressure curves at stated stroke length and stroke frequency, and meter output signal type (4-20 mA, RS485 Modbus) for SCADA integration. ABS plastic housings on the listed meters indicate general-purpose rather than explosion-proof installations, which is relevant for hazardous-area buyers in oil and gas or chemical plants.

Trade and Export Information - Shanghai Qilee Environmental Protection Equipment Co., Ltd.

Water treatment equipment made in China is typically exported under HS chapters 8421 (filtering or purifying machinery for liquids), 8413 (pumps for liquids), and 9027 (instruments for physical or chemical analysis). The two HS-coded items in this catalogue, 9027.20 for the pH meter and 9027.80 for the dissolved oxygen meter, both fall under chapter 9027, while RO membranes and filter presses generally clear under 8421 and metering pumps under 8413. Typical destination regions for Chinese water treatment equipment include Southeast Asia (Indonesia, Vietnam, the Philippines, Malaysia), the Middle East and North Africa (Saudi Arabia, UAE, Egypt, Algeria), Sub-Saharan Africa, Central Asia, and South America, where municipal desalination, industrial effluent treatment, and aquaculture projects drive recurring demand for RO membranes, dosing skids, and online analyzers. For these product categories, buyers and end-users commonly require documentation including material certificates (especially 316L stainless steel wetted parts on metering pumps and pressure vessels), hydrostatic test reports for RO housings, performance curves for membrane elements at standard test conditions (2,000 ppm NaCl at 225 psi for brackish, 32,000 ppm NaCl at 800 psi for seawater), calibration certificates for pH and DO probes traceable to NIST or equivalent, and CE or equivalent conformity marking for European-bound shipments. Packaging norms typically involve wooden crates for filter presses and RO vessels, with membrane elements sealed in vacuum bags inside cardboard boxes and dosed with preservative solution (usually 1% sodium metabisulfite) for storage life. Common Incoterms for this category are FOB Shanghai or Ningbo for container loads, with CIF to the destination port for full skid shipments; a 20 ft container typically holds several dozen 4040 membrane elements or one to two small filter presses, while 40 ft HC units are standard for full dosing skid packages. Origin context for China: the Yangtze River Delta, including Shanghai, is one of the main manufacturing clusters for RO membranes, metering pumps, and small-scale water treatment skids, with a dense supplier base supporting both domestic and export projects.

Sourcing from Shanghai Qilee Environmental Protection Equipment Co., Ltd. - Buyer Guidance

Buyers sourcing from this supplier should anchor enquiries on the four equipment families in the catalogue rather than treating it as a single-line vendor. For RO membrane items, request the specific Filmtec or Toray part number, nominal rejection rate, active area in ft², and test conditions sheet, then verify that the element is factory-sealed with intact preservative and within shelf life (typically 12-24 months from shipment). For metering pumps, ask for the flow-versus-pressure curve at 100% stroke length, wetted-part material list (PP, PVDF, 316 SS), and compatibility data for the specific chemical being dosed, since diaphragm material selection (PTFE vs. EPDM vs. Viton) is critical for sodium hypochlorite, polymer flocculants, and acidic or alkaline reagents. For sludge dewatering machines, request feed solids percentage, target cake dryness, polymer consumption in kg active polymer per tonne of dry solids, and reference installations with similar sludge type (municipal, paper mill, mining, or food processing). For the pH and DO meters (HS 9027.20 and 9027.80), confirm electrode type, reference junction, response time, output signal, and IP rating, and request a factory calibration certificate with buffer solutions used. Across all categories, buyers should ask for the CE or equivalent declaration if shipping to the EU, a commercial invoice and packing list matching the actual equipment, and ideally a pre-shipment inspection report covering visual, dimensional, and functional checks. Standard verification signals include response time on technical questions, willingness to share test data sheets, and clarity on whether the supplier manufactures in-house or assembles from bought-in components.
