<\/p>\n<\/p>\n
Traditional pumps explain a general category of mechanical machinery designed to move fluids using mechanical forces. A few examples are positive displacement pumps (piston, diaphragm, and gear pumps) and other non-centrifugal pumps. Traditional pumps transport fluid by sealing a volume of fluid and displacing it through the discharge piping. Traditional pumps are often used in applications where precise control of flow or high pressure is needed, especially when the fluids are viscous or particulate-laden.<\/p>\n
Centrifugal pumps are dynamic pumps that employ rotational energy of motion in order to transport fluids. Fluid enters the pump’s impeller along or near the axis of rotation and is forced outward by the centrifugation force through the vanes of the impeller into a diffuser or volute casing. Longgang Pump<\/b><\/u><\/strong><\/a>\u00a0mainly produces BB series, OH series, and VS series chemical centrifugal pumps, which have extensive uses in the petroleum, petrochemical, coal chemical industry, environmental protection, and water treatment industries.<\/p>\n Traditional positive displacement pumps work through mechanical displacement of fluid using pistons or diaphragms. In each stroke, a volume of liquid is displaced, irrespective of system pressure. The result is a smooth flow but has pulsating delivery. These pumps are suitable for high-viscosity fluids or when precise dosing is required.<\/p>\n Centrifugal pumps work on the basis of transferring velocity to the fluid using a rotating impeller. Fluid is fed to the center of the impeller and is flung to the periphery by centrifugal force, gaining kinetic energy which is converted into pressure energy in the volute casing. For example, Longgang LZV(OH3) single-stage vertical pipeline centrifugal pump utilizes a volute-shaped structure with a double volute design for outlets \u226580mm in order to resist radial forces efficiently and ensure rotor stiffness.<\/p>\n Traditional pumps offer highly stable flow rates even under varying pressures due to their fixed displacement nature. However, they may experience pulsation unless dampeners are installed. Centrifugal pumps provide smooth flow, but their output can vary with system resistance.<\/p>\n Longgang\u2019s BB2(LBD) heavy-duty centrifugal process pump features a double volute structure that reduces radial forces and extends bearing life, ensuring stable operation even under high pressure.<\/p>\n Positive displacement pumps can be less energy-efficient when operating at partial loads or against high backpressure. In contrast, centrifugal pumps tend to be more energy-efficient when operating near their best efficiency point (BEP). The independently developed BB2 efficient centrifugal pump by Longgang reaches a hydraulic optimum efficiency point of 90.5%, which is 3.5% higher than the national first-level energy efficiency.<\/p>\n Traditional positive displacement pumps are suited for applications requiring constant flow regardless of head conditions\u2014such as metering systems, chemical injection, and handling viscous materials like sludge or oils.<\/p>\n Longgang\u2019s centrifugal pumps serve across multiple sectors, including petrochemical refining units, coal gasification plants, power generation facilities, seawater desalination projects, and environmental engineering systems. For instance, the LY(VS4) long-axis submerged pump<\/b><\/u><\/strong><\/a>\u00a0is widely used in refineries, sewage treatment plants, and cement factories\u2014ideal for transporting clean or particle-containing corrosive media.<\/p>\n Traditional pumps typically have more complex internal moving parts, like valves or diaphragms, that require tight tolerances. Centrifugal pump designs are generally simpler with fewer moving parts\u2014mainly involving an impeller mounted on a shaft within a casing.<\/p>\n The LZV(OH3) vertical pipeline pump includes throat bushings on both sides of the impeller for axial force balance and uses a center-supported volute casing to enhance mechanical stability.<\/p>\n Positive displacement pumps may need frequent maintenance due to wear on valves or seals from high-pressure operations. Centrifugal pumps usually offer longer service intervals when operated within design parameters.<\/p>\n Longgang emphasizes easy maintenance\u2014many models allow bearing and seal replacement without disassembling piping connections. We\u00a0executes a 12\/18 months quality warranty with lifetime service support for all sold products.<\/p>\n This model features excellent hydraulic design with anti-cavitation performance and long service life. It supports applications such as urban water supply, fire pressurization systems, long-distance pipeline transport, and petrochemical processes.<\/p>\n Designed according to API610 standards, this model offers multi-point support structures for improved rotor stability under deep submersion conditions. It supports various sealing options, including dry gas seals for safe transportation of hazardous media.<\/p>\n Traditional positive displacement pumps often use cast iron or stainless steel components, depending on media compatibility, but may lack advanced material coatings for aggressive chemicals.<\/p>\nComparison of Working Principles<\/b><\/strong><\/h2>\n
