PWDDFL-type multi-suction head sludge pump features an impeller with single/double flow channels and double/multi-blades, employing high-efficiency, clog-free hydraulic design for excellent flow performance. It boasts a compact structure, small footprint, smooth operation, minimal vibration, high reliability, simple installation, and user-friendly operation. When paired with our company's electrical control cabinet, it enables automatic control functions. In addition to the common traits of centrifugal pumps, the multi-suction head vertical silt-free sludge pump possesses three unique advantages: 1. Multiple Suction Heads. Each pump is equipped with 3 or 4 suction heads, distributed across the center and corners of the sump pit. This design ensures high suction head redundancy, extensive water intake range, and reduced pit sedimentation. 2. Integrated Agitation: A mixer is installed beneath the primary suction head, stirring up settled materials in the pit to effectively prevent clogging and silt accumulation. 3. Self-Supporting Design。 Unlike other vertical sewage pumps that require brackets fixed to pre-embedded supports (which complicates both installation and maintenance), the multi-suction head pump uses its side suction heads as both intake points and structural supports. No additional installation is needed—simply place the pump in the pit and connect the discharge pipe for stable operation, with easy maintenance. This pump is primarily suitable for industries such as power plants, steel mills, coal mines, chemical plants, pharmaceuticals, municipal engineering, construction, hospitals, hotels, seawater drainage, rural biogas tanks, and agricultural irrigation. It can also handle the pumping of sludge, wastewater, urban domestic sewage or rainwater, and clean water containing solid particles or long fibers etc.

Slip on flanges, also called SO flanges, are a popular type of pipe flange designed to accept pipe into the bore/center of the flange for welding around both the Outer Diameter (OD) of the pipe and on the interior side of the connection. Design & Installation Principle The inner diameter of a slip-on flange is slightly larger than the outer diameter of the pipe, allowing the pipe to slip easily into position. After alignment, fillet welds are applied on both sides to secure the connection. This simple installation method reduces fabrication time and overall installation cost, making slip-on flanges a popular choice for large-scale projects. Standards & Size Range Our slip-on flanges are manufactured in accordance with international standards to ensure compatibility with global piping systems: ANSI / ASME B16.5 (NPS 1/2” – 24”) ANSI / ASME B16.47 (Large Diameter Flanges) AWWA C207 (Waterworks Flanges) EN 1092-1 / ISO 7005 (European Standards) Available sizes typically range from DN15 (1/2”) up to DN600 and above, depending on the applicable standard and project requirements.

DG boiler feed water pump, also known as the feeding pump is a horizontal centrifugal pump used to supply water to steam generators such as boilers. Currently, all boiler feeding pumps are centrifugal pumps, used in fuel and nuclear power plants. DG series is a common horizontal multistage centrifugal pump with a flow rate typically ranging from 10 to 500 m³/h and a head coverage of 100 to 2000 meters, operating at temperatures ≤160°C. This pump model features cast steel or stainless- steel flow components and possesses characteristics such as high efficiency and low net positive suction head. Boiler feed pumps must comply with standards like GB/T 5657 and API 610, along with specialized technical specifications such as JB/T 6614-2025. Performance range (design point) Flow rate Q: 3.75~720 m³/h Head H: 476~985 m Structural characteristics: DG type pump is a horizontal, single-suction, multi-stage segmented centrifugal pump. Both the inlet and outlet of the pump are vertically upward. The tightening bolts connect the suction section, middle section, and discharge section into a single unit. The pump rotor consists of components such as the impeller and balance disk mounted on the shaft. The entire rotor is supported by sliding bearings at both ends of the pump shaft. The bearings are lubricated with oil and cooled by circulating cold water. The axial force of the rotor is balanced by the balance disk. The shaft seal adopts either packing or mechanical sealing. Sealing glands are installed at both ends of the shaft, containing soft packing or mechanical seals. Pressurized water is directed into the sealing glands to provide water sealing and cooling functions. A replaceable bushing is fitted at the shaft seal to protect the pump shaft. The pump is directly driven by the motor through an elastic coupling, and from the motor end, the pump rotates clockwise. The boiler feeding water pump is a horizontal, two-end supported, radially split, radial-flow centrifugal pump used to provide feedwater equivalent to steam discharge for steam generators (such as boilers or nuclear reactors). During the operation of the boiler feedwater pump, it is necessary to ensure a minimum flow rate to prevent damage to the pump caused by vaporization or cavitation due to the increase in medium temperature under low flow conditions. This is usually achieved by installing a minimum flow valve (automatic recirculation valve). The pump can only operate within the specified parameters; It is not allowed to operate for a long time when the outlet valve is closed or the opening is very small; Cannot close the suction valve for operation; The conveying medium must not contain air or gas; Materials that cannot transport particles on the conveyor belt; Before starting, a check is required. Before starting the pump, check the bolts, pipelines, instruments, valves, oil level, and motor direction; Open the suction valve and close the outlet valve when starting, fill the pump with liquid, start the motor, and slowly open the outlet valve after normal operation. During the operation of the pump, it is necessary to regularly monitor the pressure, flow rate, temperature, vibration, and lubrication conditions. The temperature rise of the bearing should not exceed 35 ℃ above the ambient temperature, and the maximum temperature should not exceed 75 ℃. It is necessary to check whether there is balancing liquid flowing out of the balancing device (connected to the suction section through the balancing water pipe). When stopping the pump, the outlet valve should be closed to the minimum flow rate first, then the motor should be stopped, and finally the outlet valve should be closed. After the pump stops steadily, the suction valve should be closed. It is strictly prohibited to close the suction valve first.
