Product Description: GDL Multistage Pipeline Centrifugal Pump Product Introduction:GDL Multistage Pipeline Centrifugal Pump is a medium conveying device where the flowing medium (gas and liquid, or a mixture of suspended particles with gas or liquid) enters from the blade rotation shaft root (inlet). The medium relies on high-speed rotating blades to obtain centrifugal force, generating high pressure, and flows out from the pressure relief port (outlet). The GDL Multistage Pipeline Centrifugal Pump combines two or more pumps with the same function. In the fluid channel structure, the medium pressure relief port of the first stage is connected to the inlet of the second stage, the medium pressure relief port of the second stage is connected to the inlet of the third stage, and so on. This series mechanism forms a multistage centrifugal pump. The significance of the GDL Multistage Pipeline Centrifugal Pump lies in increasing the set pressure.The GDL Multistage Pipeline Centrifugal Pump adopts a pipeline structure for easy installation, small footprint, aesthetically pleasing appearance, energy efficiency, and wide application range. The pump's suction and discharge ports are located on the same straight line. The rotor assembly consists of components such as the shaft, impeller, impeller retaining sleeve, and shaft sleeve. The inlet section, middle section, and outlet section are connected by tension bolts. The shaft seal uses mechanical seals, lubricated and cooled by pressure water from the balance chamber. It is a pump type for conveying cold and hot water or liquids with physical and chemical properties similar to water in various industries.Pipeline Centrifugal Pump——》Choose『sanli』！GDL Multistage Pipeline Centrifugal Pump Installation Precautions:a) During installation, the pipeline weight should not be borne by the pump, otherwise it may damage the pump;b) The pump and motor are an integrated structure, calibrated by the manufacturer before leaving the factory, so no adjustment is needed during installation, making it very convenient;c) Before installing the pump, carefully check the pump flow channel for any hard objects that may affect pump operation (such as stones, iron sand, etc.) to avoid damage to the flow components during operation;d) During installation, the anchor bolts must be tightened, and the pump should be inspected periodically to prevent loosening, to avoid severe vibration during startup affecting performance;e) For maintenance convenience and safety, install a regulating valve in the pump's inlet and outlet pipelines and a pressure gauge near the pump's inlet and outlet. For high head, to prevent water hammer, also install a check valve before the outlet gate valve to handle sudden power loss and other power failure incidents, ensuring the pump operates under working conditions and extending its service life;f) When the pump is used in suction applications, a bottom valve should be installed, and the inlet pipeline should not have too many bends. There should be no water or air leakage to avoid affecting the pump's suction performance;g) To prevent impurities from entering the pump and blocking the flow channel affecting performance, install a filter before the pump inlet;h) Before installing the pipeline, rotate the pump's rotor components. There should be no friction or jamming sounds; otherwise, disassemble the pump to check the cause.GDL Multistage Pipeline Centrifugal Pump Main Applications:1. Suitable for boosting water supply in high-rise buildings, garden irrigation, cooling tower water supply, long-distance water transport, air conditioning, refrigeration flushing, bathroom cold and hot water circulation pressurization.

Suitable for conveying non-corrosive liquids, in fixed equipment in coal mines Class I and factory Class IIA, IIB, temperature groups T1, T2, T3, T4, and other industrial sites with mixtures. Operating temperature below 80°C.5. Suitable for conveying corrosive liquids in chemical, pharmaceutical, petroleum, food, and other industries, in fixed equipment in coal mines Class I and factory Class IIA, IIB, temperature groups T1, T2, T3, T4, and other industrial sites with hazardous mixtures. Operating temperature below 150°C.GDL Multistage Pipeline Centrifugal Pump Working Principle:When the motor drives the impeller on the shaft to rotate at high speed, the liquid filled in the impeller is thrown from the center of the impeller along the flow channels between the blades to the periphery under centrifugal force. Due to the action of the blades, the pressure and velocity of the liquid increase simultaneously. The liquid is directed to the next stage impeller through the guide shell's flow channel. In this way, the liquid passes through all the impellers and guide shells successively, further increasing its pressure energy. By stacking each impeller stage by stage, a certain head is achieved.The GDL Multistage Pipeline Centrifugal Pump is energy-efficient, has a small footprint, is easy to install, and has stable performance. The outer casing is made of 1Cr18Ni9Ti stainless steel, and the shaft seal uses wear-resistant mechanical seals, ensuring no leakage and long service life. Axial force is balanced hydraulically, resulting in smooth operation and low noise. Installation conditions are superior to DL-type pumps, allowing easy installation in any horizontal pipeline section. It has a wide performance range, with inlet and outlet diameters of 25-100 mm, flow rate of 2-72 tons per hour, head of 25-150 meters, totaling 9 series and over 70 specifications. It meets the water supply, drainage, and fire protection needs of high-rise buildings, deep wells, mines, etc. It is a pump type for conveying cold and hot water or general media with physical and chemical properties similar to water in various industries.GDL Multistage Pipeline Centrifugal Pump - Choose『sanli』, creating with "innovation" and serving with "heart" as a pump manufacturer,【Customization Supported】, timely delivery, door-to-door service, providing production+ design + installation + maintenance one-stop service!
