Submersible Centrifugal Pump

The submersible centrifugal pump is a general type of submersible water pump that integrates the motor and the centrifugal pump body coaxially and works by being fully submerged below the liquid surface. According to the medium and application scenarios, it is divided into four main series: QY/QDX type oil-immersed submersible pumps (clear water/low-salinity wastewater, closed impeller, cast iron pump housing, agricultural irrigation/city water supply); WQ type submersible sewage pumps (containing solid particles wastewater/sludge, vortex type/half-open impeller, particle size over 20-80 mm, municipal sewage treatment plants/building site drainage); BQS type mining submersible pumps (coal mine/metals mine drainage, high-chromium flow components + explosion-proof motor, national mining safety mark certification, head can reach 1000 m); QJ type well submersible pumps (deep well water extraction, multi-stage impeller + stainless steel/copper alloy, groundwater extraction/ground source heat pump, head 20-600 m).

IP68 waterproof, F/H insulation level - Submersible motor with fully enclosed oil-filled/water-filled structure, IP68 protection (can be submerged underwater for a long time up to 20 meters), F/H insulation with a temperature range of 155-180°C, built-in overheat protector
Variety of impellers, suitable for different media - Closed impeller (efficient for clear water), semi-open impeller (for solid and sewage), vortex impeller (no blockage for large particles), cutting impeller (for fiber cutting), maximum particle size 80 mm
Material options, long service life - Pump casing made of cast iron/stainless steel/high-chromium alloy, impeller made of copper alloy/stainless steel/high-chromium, shaft made of 2Cr13/3Cr13 stainless steel, mechanical seal made of silicon carbide/hard alloy
Coupling/grounding/floating installation - Coupling type (automatic alignment with guide rail, maintenance-free underwater entry), ground type (directly placed on the pool bottom), floating type (fixed by float, water level self-adaptive), flexible adaptation

High-pressure operation: Perfect for pumping wastewater and slurry in commercial buildings.
Heavy-duty design: Specifically designed to handle challenging tasks such as sand and mud suction.
Semi-submersible: Easy to install and maintain, highly efficient utilization.
Industrial grade: Robust structure ensures durability in harsh environments.
Customizable power options: Offers various power levels to meet specific needs.

The key feature of the submersible centrifugal pump is "submerging underwater and starting to operate immediately", and the core scenarios are as follows:
Municipal drainage (WQ series with the largest single unit)
Urban rainwater pumping stations, sewage lift pumping stations: WQ series coupled installation, automatic start and stop, unmanned operation
Wastewater treatment plants: inlet pump rooms, sludge return, discharge pumps
Undercrossing tunnel drainage for overpasses, flood drainage for subway stations
Drainage in residential basements and garages
Construction site drainage (QY/WQ series)
Basement water extraction, surface water extraction at excavation sites
Drainage in construction sites (QY freshwater type)
Mine drainage (BQS series)
Main drainage in coal mines, drainage at mining workfaces
Drainage in metal mine tunnels, drainage in open-pit mines
Water surge treatment in tunnel projects

Full-process modern production base: The company has built an intelligent complete production area by itself, equipped with 126 main production equipment and 34 sets of specialized precision processing devices, covering all production processes of the entire industrial chain: model design and mold making, pump body casting, heat treatment, precision machining, complete machine assembly, and complete machine performance testing, all completed in one step. The production end adopts CAD computer-aided design and CAE engineering simulation technology, which can achieve three-dimensional modeling, assembly interference verification, stress analysis, and CFD fluid dynamics simulation, precisely optimizing the performance of the pump body; self-developed optimized impeller structure significantly extends the service life of the equipment and effectively reduces the post-installation operation costs for customers. The annual casting capacity of the factory can reach several thousand tons, and all raw materials are selected from high-grade domestic manufacturers; the self-developed slurry pump has a service life 2-5 times longer than similar conventional products in the market, with outstanding wear resistance and durability advantages. The factory is equipped with two sets of high-pressure and low-pressure pump testing workstations, and all finished products undergo full inspection before leaving the factory, achieving a 100% qualified rate upon leaving the factory.
