Products
| Submersible thruster In the water treatment process, submersible plug flow device is widely used in oxidation ditch plug flow, mixing of all kinds of biochemical pool, river antifreeze, landscape water circulation, etc. The submersible thruster is composed of submersible motor, reducer, impeller and installation system. It is characterized by small matching power, low speed, large impeller diameter, large volume flow field and wide service range. Swept back banana blade paddle design, with self-cleaning function, using polyurethane or reinforced glass fiber reinforced plastic molding, has the advantages of light weight, high strength, corrosion resistance, etc., its excellent hydraulic performance, can ensure that in the low-speed movement state and liquid have good resistance effect, so as to create a soft water flow. This series of products not only have the function of pushing and creating water flow, but also have the function of stirring. |

| Submersible mixer As one of the key equipment in water treatment process, submersible mixer can realize the homogenization of solid-liquid two-phase flow and solid-liquid gas three-phase flow in biochemical process. It consists of submersible motor, impeller and installation system. The submersible mixer is of direct connection structure. It has the advantages of compact structure, low energy consumption and easy maintenance. The impeller is molded by investment casting or stamping, with high precision, large thrust, beautiful streamline shape and anti winding function. The system is suitable for the place where solid-liquid mixing and mixing are needed. |

| Suspended carrier thruster In the production process of modern wastewater treatment plant, the carrier of biofilm used in MBBR (moving bed biofilm reactor) process is usually HDPE (high density polyethylene), that is, suspended carrier. Its buoyancy density is similar to that of water, and its large surface area can promote the growth of biofilm. The QMD system submerged biofilm suspended carrier plug developed by our company is a new type of plug to prevent biofilm carrier from settling, maintain its flow and suspension, and enhance its mixing performance. |
 |
| Submersible aerator QXB submersible centrifugal aerator is used in aeration tank and aerated grit chamber of sewage treatment plant to aerate and mix mixed liquid of sewage sludge, biochemical treatment of sewage or aeration of breeding pond. |
 |
| Submersible sewage pump Submersible sewage pump is a product researched and developed by our company on the basis of absorbing the advanced technology of famous German pump making company. It has high technical starting point, obvious energy-saving effect, strong matching and wide applicability. It has been listed as a key imported product by the former state machinery Commission, and has passed the export quality approval and CE certification. After being put on the market, with its unique function and reliable quality, it is welcomed and praised by the majority of users. The submersible sewage pump produced by our company has compact coaxial structure, high efficiency, convenient installation and maintenance, and strong adaptability. Its installation methods include fixed wet installation and mobile installation. |

| Multi surface mixer Multi curved mixer is widely used in environmental protection, chemical industry, energy, light industry and other industries where solid, liquid and gas mixing of liquid is needed, especially in the coagulation tank, regulating tank, anaerobic tank, nitrification and denitrification tank of sewage treatment process. This is a mixing device that can create large volume flow, and can obtain large area circulation and soft water flow with less power. Unique impeller structure design, maximize the fluid characteristics and mechanical movement perfectly combined. The curved surface of multi curved impeller is a curved body formed by the equation xy = B and the curve rotating along the y-axis; In order to cater to the water flow, the design of water inflow from the center of the impeller, on the one hand, reduces the inflow turbulence, on the other hand, ensures that the pressure of the night body on the impeller surface is uniform, so as to ensure the balance of the whole machine in motion. Eight guide vanes are evenly distributed on the involute multi arc surface. With the help of liquid self weight pressure as supplement, the potential energy obtained by water inflow and the centrifugal force generated by impeller rotation form kinetic energy. Under the condition of gravity acceleration, the liquid makes tangent movement along the circumference of impeller. Under the reflection of pool wall, the bottom-up circulating water flow is formed, Therefore, the cross flow in the axial (y) and radial (x) directions can be obtained. It is because of the structural characteristics of the impeller of the multi curved surface mixer and the installation characteristics close to the bottom of the tank that it can obtain the ideal mixing effect and effectively eliminate the mixing dead angle. |
 |
| Sand water separator The sand water separator is used in the grit chamber of sewage treatment plant to separate the sand water mixture discharged from the grit chamber. The sand water separator is composed of shaftless screw, lining strip, U-shaped groove, water tank, deflector, outlet weir and driving device. The sand water mixture is fed into the water tank from the top of one end of the separator. The medium and heavy mixed liquid, such as sand particles, will be deposited at the bottom of the groove. Under the push of the screw, the sand particles will be lifted along the bottom of the inclined U-shaped groove. After leaving the liquid level, they will continue to move for a certain distance. After the sand particles are fully dehydrated, they will be discharged to the sand bucket through the sand discharge port, and the water separated from the sand will be discharged from the overflow port and sent to the water inlet tank in the plant. |
 |
| Submersible axial flow pump Submersible axial flow pump submersible axial flow pump is a traditional pump, motor unit replacement products, pump machine can be long-term submerged operation, has a series of outstanding advantages. The submersible axial flow pump can be used for farmland drainage and irrigation, industrial and mining docks, urban construction, power station water supply and drainage. Submersible axial flow pump is suitable for high lift and large flow. |
