Guangdong Yongli Pump Industry Co., Ltd. products

The new generation of horizontal multi-stage pump design, DW (D) is an advanced horizontal multi-stage centrifugal pump, with the entire flow passage components made of stainless steel 304 or 316. By adopting a unique stamping process, the final product has excellent quality and efficiency, which can meet the complex application requirements in today`s construction services and general industry, especially when higher lift requirements are needed.

The impeller guide vanes are made of stainless steel plates by stamping and welding. Equipped with a long shaft motor, axial inlet and radial outlet. Compact structure with low noise. Suitable for mildly corrosive liquids. Small installation space. The PC series automatic pump consists of an electric pump and an electronic pressure controller, achieving automatic control function. The system has a simple structure and does not require pressure sensors, pressure switches, pressure tanks, or check valves, making it easier to use and maintain. This series of products has a factory set starting pressure value. When the pipeline pressure is lower than this pressure value, the electric pump starts working to meet the user`s water demand; When the user does not use water, the electric pump stops working, thereby extending the service life of the electric pump and saving electricity consumption 

The impeller guide vanes are made of stainless steel plates by stamping and welding. Equipped with a long shaft motor, axial inlet and radial outlet. Compact structure with low noise. Suitable for mildly corrosive liquids. Small installation space. IQ intelligent series variable frequency constant voltage system, with stable water supply pressure, current overload protection function, power-off restart function, overcurrent components made of stainless steel material, and low water level protection function

The excellent design features give DL stainless steel vertical multi-stage inline pump a high level of quality and optimal performance. DL aims to meet the stringent requirements of pumping applications in today`s construction services and industrial and manufacturing industries. DL includes multiple models with different numbers of stages, which can meet flow rates of up to 2500 liters per minute and a head of 206 meters, respectively, Vertical design occupies a small area, greatly reducing installation space. Very suitable for scenarios with limited installation space. The `inline` suction and discharge ports simplify installation and pipeline layout All overcurrent components are made of high-quality stainless steel, which has excellent corrosion resistance and higher durability. A smooth and uniform surface ensures optimal performance, maintains high efficiency throughout the entire lifespan of the pump, and reduces power consumption, thereby lowering.

Adopting stainless steel precision casting shell, it has the characteristics of corrosion resistance, environmental protection, high head, and large flow rate. The oil chamber adopts a fluorine rubber double-sided mechanical seal, and the outer chamber adopts a single-sided gas rubber mechanical oil seal structure, effectively reducing the problem of sealing water ingress caused by friction between the skeleton oil seal and the shaft. The motor adopts high-temperature wire, F-class insulation, and thermal protection device, effectively extending the service life of the pump. According to customer requirements, a mixing device can be equipped, which generates strong mixing force with the rotation of the motor shaft, and mixes the sediment in the sewage tank into suspended solids before being discharged. It can also be equipped with a cutting device, which can remove long fibers, plastics, paper bags, straw and other debris from sewage. 5. Explosion proof level is Ex.

Execution standard: JB/T10601-2006ZW self-priming non clogging sewage pump, a new type of pump that integrates self-priming and sewage discharge. The hydraulic design of this series of pumps is unique. The impeller is enclosed in a separate impeller chamber, which is connected to a pressurized water chamber. When the impeller rotates, the liquid inside the pump generates a strong axial vortex, creating a vacuum at the inlet and a head at the outlet. Therefore, impurities can be discharged from the pressure chamber, so its flow channel is completely unobstructed, and its sewage discharge effect is unparalleled by other self-priming sewage pumps. The sewage pump produced by our unit does not require the installation of a bottom valve like a general self-priming water pump, and can also suck and discharge sewage containing large solid particles, long fibers, sediments, waste impurities, and all engineering wastewater.

According to the GB/T 24674-2021 standard, a double end mechanical seal is used between the water pump and the motor, and an "O" - shaped oil resistant rubber seal ring is used for static sealing at each fixed stop seal. 

GZA (S)/DZA (S) is the most advanced series of end suction centrifugal pumps, with its liquid flow section made entirely of stainless steel 304 or 316. Compliant with DIN24255 standard, it has excellent quality and efficiency to meet the complex application requirements of today`s construction services and general industry. There are two versions of the GZA (S)/DZA (S) design: the GZA (S) motor is tightly coupled with the water pump, and the impeller is installed on the extension shaft of the motor. The DZA (S) motor adopts standard IEC motor and is connected to the water pump through a short shaft and an intermediate connecting plate. This makes it convenient to replace the motor immediately when needed and allows users to choose to use their favorite motor. GZA (S)/DZA (S) is equipped with IP55 weatherproof rating, IEC standard, aluminum frame motor. Starting from 11kW, the motor frame should be made of cast iron. The snail shell is designed as an integrated component
