Import 5. Wq Submersible Sewage Pump — Buy in wholesale FOB from Supplier in China

The 5. Wq Submersible Sewage Pump from Ideal Machinery Co. Ltd. is a centrifugal submersible pump designed for handling sewage and wastewater containing solid particles. It operates fully submerged, with the motor and pump body integrated into a single unit that can operate continuously underwater. The WQ series designation indicates a non-clogging impeller design capable of passing solid waste without jamming. The pump handles municipal wastewater, industrial effluent, and raw water transfer applications. Ideal Machinery manufactures this unit at their facility in Zibo, Shandong Province, China. The pump body and impeller are typically constructed from cast iron, with critical wear surfaces often hardened for extended service life. Standard submersible sewage pumps in this class operate across a flow range of approximately 10 to 5,000 cubic metres per hour, with heads from 5 to 60 metres depending on motor power and impeller specification. The motor is oil-filled or water-filled for cooling and insulation, with IP68 protection standard for continuous submersion. Mechanical seals prevent water ingress to the motor chamber, with double mechanical seals common for demanding applications. Cable entry sealing and cable quality are critical reliability factors for long-term submerged operation.

The impeller configuration determines solids-handling capability. Single-channel or vortex impellers pass larger solids but with reduced efficiency, while multi-channel designs offer better efficiency with smaller maximum particle size. Typical maximum particle passage for WQ-series pumps ranges from 35 mm to 50 mm for standard models. The hydraulic components are precision-machined to maintain balanced operation and reduce vibration. Bearing systems support the rotating assembly, with heavy-duty designs specified for continuous duty cycles. Motor insulation class is typically F (155 degrees Celsius) or H (180 degrees Celsius), allowing sustained operation at elevated temperatures. Thermal overload protection is integrated into the winding or control panel. For abrasive applications, optional hard-alloy impeller materials or coatings extend wear life significantly. The pump coupling system allows removal of the motor and hydraulics without disturbing the discharge piping, reducing maintenance downtime. Standard discharge connections follow flange dimensions per GB, DIN, or ANSI standards depending on market destination.

Buyers of WQ submersible sewage pumps include municipal water authorities, industrial plant engineers, wastewater treatment contractors, and commercial building facilities managers. The pump suits installation in wet wells, sumps, septic tanks, and portable dewatering setups. For import from China, buyers should confirm the exact motor power rating, voltage and frequency specifications, and whether the motor is suitable for local electrical standards. The supplied cable length must be confirmed, as standard lengths vary and extension below water level requires proper sealing. Incoterms and port of dispatch from Shandong should be clarified with Ideal Machinery directly, as these are not stated in the listing. Buyers should request performance curves showing flow rate, head, power consumption, and efficiency across the operating range. NPSH (Net Positive Suction Head) requirements affect wet well design and must be verified. For projects requiring certification, the buyer must confirm with Ideal Machinery whether CE marking, ISO 9001 quality system certification, or specific test reports are available for the ordered configuration.

Ideal Machinery Co. Ltd. is located at No. 1816 Industry Zone, Zibo, Shandong Province, 265550, China. Zibo is an industrial city in northern China with established manufacturing infrastructure for pumps, ceramics, and petrochemical equipment. The company holds a harbor trust tier, which indicates a basic verified presence on the marketplace without advanced verification signals. The response rate is recorded at 0.00 percent with zero average response hours, suggesting that direct inquiry response performance data is either not tracked or not available through this channel. Buyers should note that this listing profile provides limited transaction history or third-party verification detail.

The supplier's product description positions the WQ submersible sewage pump for municipal wastewater, mining, hospitality, building services, raw water transfer, flood control, agricultural irrigation, and chemical medium transfer. This broad application scope suggests a general-purpose manufacturing capability rather than specialisation in any single sector. The description does not state factory size, annual output, design engineering resources, or quality management certification. No client references, project installations, or case studies are provided. Buyers should conduct direct due diligence with Ideal Machinery to establish production capacity, in-house testing facilities, and whether the company manufactures the pump itself or sources from a third-party factory. Requesting factory audit documentation, material certificates for cast iron components, and motor test reports would be prudent steps before placing a substantial order.
