When the centrifugal pump is turned on, the impeller rotates counter clockwise, creating a low-pressure area in the eye of the impeller. As the pressure is lower than atmosphere, water is pushed up into the suction pipe by atmospheric pressure, which subsequently forces all the air in the suction line into the pump. The self-priming pump mixes the air with the recirculating water in the casing. As this occurs, the air separates from the liquid and discharges from the casing. When all the air in the suction line is displaced, the pump delivers the flow like any other centrifugal pump. ZX serives self priming pump is a horizontal self priming centrifugal pump. Compared with other types of self-priming centrifugal pumps, this type of pump has the simplest structure because it has no check valve itself; Small size, light weight, high efficiency, and special consideration in design. Compared with pumps of the same caliber, the displacement is large and the performance is high. https://www.hongarvalve.com/uploads/43677/video/2025071215082580d9e.mp4 2025-07-12T15:28:10+08:00 yes no https://www.hongarvalve.com/pipeline-pump/centrifugal-pump/horizontal-multistage-centrifugal-pump.html https://www.hongarvalve.com/uploads/43677/small/horizontal-multistage-centrifugal-pump94a1f.jpg Horizontal Multistage Centrifugal Pump Horizontal multistage centrifugal pump is a type of centrifugal pumps that contain two or more impellers. Each stage in a multistage pump acts like a separate pump. They are primarily used in services requiring moderate to high TDH (Total Dynamic Head). All stages of a multistage are places within the same housing unit and installed on a single shaft. Up to eight stages can be placed on a single horizontal shaft. If you need more than that, you can use multiple shafts. Each stage reduces the head by the same amount. Chongqing Hongar is the leading horizontal multistage centrifugal pumps suppliers in china for over three decades. Our series of multistage centrifugal pumps are built to world-class standards. The user-friendly design makes the pump suitable for both industrial and domestic applications. D-type horizontal multistage centrifugal pump has the characteristics of high efficiency, wide performance range, safe and stable operation,low noise, long life,convenient installation and maintenance, etc.For conveying clean water or other liquids with physical and chemical properties similar to water. It can also be used to transport hot water, oil, corrosive or abrasive media by changing the material of pump flow parts, the sealing form and increasing the cooling system.The product implements the standard of JB/T1051-93 "Type and Basic Parameters of Multistage Clean Water Centrifugal Pump".We companyhas strong technical force, rich production experience and perfect testing methods to ensure stable and reliable product quality. https://www.hongarvalve.com/uploads/43677/video/20250718114318f1607.mp4 2025-07-18T11:43:37+08:00 yes no https://www.hongarvalve.com/pipeline-pump/screw-pump/single-screw-pump.html https://www.hongarvalve.com/uploads/43677/small/single-screw-pumpc4af1.jpg Single Screw Pump A screw pump is a rotary pump that relies on the volume change and movement of the meshing space formed by the pump body and the screw to transport liquid or increase its pressure. Screw pumps are divided into single screw pumps, double screw pumps and three screw pumps according to the number of screws. When the active screw rotates, it drives the driven screw that meshes with it to rotate together, and the volume of the screw meshing space at one end of the suction chamber gradually increases, and the pressure decreases. The liquid enters the meshing space volume under the action of the pressure difference. When the volume increases to form a sealed chamber, the liquid moves continuously along the axial direction in each sealed chamber until it reaches one end of the discharge chamber. At this time, the volume of the screw meshing space at one end of the discharge chamber gradually decreases, and the liquid is discharged. The working principle of the screw pump is similar to that of the gear pump, except that the screw replaces the gear in structure. The table shows the characteristics and application range of various screw pumps. The flow and pressure pulse of the screw pump are very small, the noise and vibration are small, and it has self-priming ability, but the screw processing is more difficult. The pump has two structures: single suction and double suction, but the single screw pump only has single suction. The pump must be equipped with a safety valve (single screw pump does not need to be equipped) to prevent the pump or prime mover from being damaged due to some reasons such as blockage of the discharge pipe, which causes the pump outlet pressure to exceed the allowable value. https://www.hongarvalve.com/uploads/43677/video/2025071815191581f66.mp4 2025-07-18T15:54:46+08:00 yes no https://www.hongarvalve.com/pipeline-pump/slurry-pump/vertical-slurry-pump.html https://www.hongarvalve.com/uploads/43677/small/vertical-slurry-pump814a4.jpg Vertical Slurry Pump The vertical slurry pump, also known as the vertical mud pump, employs an auxiliary impeller to reduce impeller back pressure and extend seal service life. Meanwhile, the wetted sections are anti-abrasion and constructed of white wear-resistant cast iron. Furthermore, compared to horizontal slurry pumps, vertical mud pumps are lighter in weight, take up less floor space, and require less installation and maintenance. Vertical slurry pump is a customizable pumps intended to save maintenance and operating expenses. They take up less floor area than horizontal pumps and have worn strong metal or rubber components. Vertical sump pump is a suited explicitly for abrasive slurries. They are commonly utilized with floor sumps in process plants, mill scale pumping applications in steel industries, and pumping of machine tool cuttings and wood chips because of their resilience and ease of maintenance. https://www.hongarvalve.com/uploads/43677/video/202508031556289cb29.mp4 2025-08-03T16:11:56+08:00 yes no https://www.hongarvalve.com/pipeline-pump/slurry-pump/submersible-slurry-pump.html https://www.hongarvalve.com/uploads/43677/small/submersible-slurry-pump60169.jpg Submersible Slurry Pump The submersible slurry pump is hydraulic machinery, the motor and the pump of which are coaxially working submerged in medium . The wetted parts of the pump are made of high chromium wearable alloy , so the pump has good wear resistance and large flowing passage. It is applicable for conveying medium such as sludge, ore slurry, coal slurry, sandstones containing big solid particles. Submersible Slurry Pump with Agitators specifically designed for handling slurries with a high content of abrasive solids. The submersible slurry pump have been extremely successful for clients operating in specialized sectors who face severe conditions and solve very difficult applications. The pumps are positioned as submersible dredge pumps for marine and energy sectors as well a in mining for minerals and other materials. Handling slurries with up to 70% solids content and specific gravity up to 1.7, with a capacity of up to 5,300 gpm at 275 feet of head. https://www.hongarvalve.com/uploads/43677/video/20250803165215ca75e.mp4 2025-08-03T17:10:58+08:00 yes no https://www.hongarvalve.com/pipeline-pump/slurry-pump/horizontal-slurry-pump.html https://www.hongarvalve.com/uploads/43677/small/horizontal-slurry-pump4ef75.jpg Horizontal Slurry Pump The ZJ Series Horizontal Slurry Pump is a single-stage, single-suction centrifugal slurry pump with a simple structure for easy maintenance; its working principle is that the impeller rotation generates centrifugal force, which sucks the solid-containing slurry axially, throws it to the edge of the pump casing, and finally discharges it from the outlet. Constructed with robust materials to resist abrasion from heavy slurries, this pump is equipped with a specially designed impeller that creates turbulent flow for efficient solids handling and anti-clogging, making it applicable to industries such as mining (for transporting ore and tailings), mineral processing, dredging (for moving sediment and gravel), and wastewater treatment. https://www.hongarvalve.com/uploads/43677/video/202508061012147c280.mp4 2025-08-06T10:41:21+08:00 yes no https://www.hongarvalve.com/pipeline-pump/metering-pump/hydraulic-diaphragm-metering-pump.html https://www.hongarvalve.com/uploads/43677/small/hydraulic-diaphragm-metering-pumpb3290.jpg Hydraulic Diaphragm Metering Pump Hydraulic Diaphragm Metering Pump Hydraulic Diaphragm Metering Pump is a excellent and reliable chemical feeding dosing pumps with rugged construction design.
