Specialized Water Submersible Products Series

Ultra-high-head small-diameter submersible electric pump

The ultra-high-head, small-diameter, high-temperature submersible electric pump product is designed and developed by seamlessly integrating our company's mature submersible pump technology with submersible oil pump technology. The unit comprises components such as a submersible oil motor, protector, pump, and cable, among others.

Subsea Jetting Pumps

The deep-sea jet pump is a critical component of subsea trenching machines, enabling efficient, low-cost operations through hydraulic jetting. The motor in this product features either a wet-type oil-filled or water-filled design and incorporates a combined anti-sand sealing system, ensuring high reliability. The oil-filled version boasts a more compact design and can withstand temperatures up to 180°C. Meanwhile, the hydraulic components have been meticulously optimized via fluid simulation analysis, delivering exceptional efficiency and excellent resistance to clogging. Additionally, all parts and connectors that come into contact with seawater are crafted from premium, corrosion-resistant materials, making the product renowned for its outstanding performance, dependable operation, and ease of maintenance.

Seawater Lift Pumps

The seawater boosting pump features a submersible design, with the motor and pump working together underwater—quietly, compactly, and easy to install and maintain. It also supports automatic protection and remote control capabilities. All components and connections that come into contact with seawater are crafted from high-quality, corrosion-resistant materials, ensuring excellent performance and reliable operation.

Deep-sea Electric Pumps

Providing hydraulic power supply in deep-sea environments, it can be applied to a variety of underwater marine equipment.

Deep-sea Construction Auxiliary Power Motors

The deep-sea construction auxiliary power motor is a product independently developed by our company, offering a viable alternative to imported products. This innovation helps break the market monopoly held by foreign companies and significantly reduces procurement costs for our customers.

Deep-diving Rigid Pipe Lift Pumps

The deep-submergence rigid pipe lift pump, designed for vertical operation and featuring excellent particle-passing capabilities, is a critical piece of equipment used in deep-sea mining for hydraulically transporting ore particles. Powered by a multi-stage centrifugal pump, it efficiently conveys manganese nodules from the underwater relay chamber through the mineral-lifting rigid pipe all the way to the surface mining vessel. At its core, the pump leverages pressurized water flow as a carrier medium, enabling the upward movement of ore particles against gravity.

Mining Flameproof Submersible Electric Pumps

The BQW explosion-proof submersible electric pump for mining applications consists of a single-stage or double-suction multistage centrifugal pump paired with a water-cooled, explosion-proof submersible motor designed specifically for mining use. The pump features an external mounting configuration, with the pump positioned above the motor—making it an "upper-pump" design—and both components are connected via a coupling. The entire unit is fully submerged in water during operation, and an additional suction hood helps efficiently cool the motor. This pump-motor assembly can be installed either vertically, horizontally, or at an inclined angle, offering versatile deployment options for various mining environments.

Submersible Sewage Pumps

Submersible sewage pump, designed for vertical installation with the pump and motor mounted on the same shaft. The submersible motor is positioned above the water pump, and its cooling feature allows it to operate either fully or partially submerged in water. This design effectively lowers the suction depth, enhancing sewage discharge performance. The unit boasts a compact structure, minimal footprint, and easy installation and maintenance—delivering high efficiency with remarkably low failure rates.

Long-Distance Water Supply Systems

The remote water supply system is primarily divided into four key modules and three types of vehicles. The four modules are the water-suction module, pressure-boosting module, water-delivery module, and bridge-road module, while the three vehicle types include the pump truck, hose-laying vehicle, and bridge-road vehicle. This system can transport natural water sources like rivers, lakes, and seas—as well as specialized liquids—over long distances, utilizing large-scale equipment and extensive pipeline networks stretching several kilometers to reach their intended destinations.

Mobile Pumping Stations

The mobile pump station consists of a diesel engine, a diesel-engine-powered fuel tank, a submersible pump, a hydraulic system, a hydraulic hose reel, a vehicle chassis, fire hoses, and a DC power supply. This product boasts excellent power performance, high reliability, and an affordable price.

Bottom-Suction Submersible Electric Pumps

Down-suction submersible electric pump, designed for vertical installation with the motor positioned above and the pump below. It features a down-suction immersed impeller directly mounted on the motor shaft extension, creating an integrated motor-pump unit that boasts a compact design, minimal footprint, and small overall dimensions. This model can be manufactured as a multi-stage pump, achieving head heights exceeding 150 meters. The pump operates smoothly, is easy to operate, simple to install, convenient for maintenance, and highly standardized.

Amphibious motor

The submersible motor is a complementary device for various sewage pumps or gearboxes, integrated seamlessly with the pump or gearbox. It can either be submerged in wastewater of different qualities—or operate safely and reliably in air over extended periods.

Submersible Cryogenic Motor

The submersible cryogenic motor is a submerged, cryogenically resistant induction motor that matches the technical standards of equivalent foreign products and currently holds a leading position in China, making it a viable alternative to imported counterparts.
