Understand Your Application Requirements
Define Flow Rate and Pressure Needs
Picking the proper multistage pump starts with grasping your setup’s fluid movement demands. Figure out the needed flow rate (Q) and lift or force (H). For example, if your task includes shifting liquids across great lengths or to tall heights, you will require a pump able to provide a strong force. Longgang’s LDD (BB4) high-pressure segmented multistage pump manages a head up to 3000m and a working pressure of 30MPa. This setup makes it suitable for those situations.
Identify Fluid Type and Temperature
Figuring out what kind of liquid you are handling proves vital. Is it pure water, a thick mixture, harsh chemicals, or fuel oils? Also, note the heat span. For instance, if you handle warm fuel oils or damaging substances, you need a pump that can endure tough settings. The LTD (BB5) model from Longgang handles temperatures from -80℃ to +450℃. It fits well for oil refining and chemical plant uses.
Determine System Operating Conditions
Think about setting up site elements like surrounding heat, height level, open area, and energy source. These aspects will affect whether you need a flat or upright setup. They also influence what sort of closing methods or support kinds are required.
Know the Basics of Multistage Pumps
What Makes a Pump “Multistage”
A multistage pump holds two or more blades fixed on the same rod inside one cover. Each level boosts the force step by step as the liquid moves through.
Benefits in High-Pressure Applications
Multistage pumps work well for creating a strong force with fairly small flow amounts. They suit boiler water supply setups, water purifying plants using reverse osmosis, and line transfer.
Common Industries and Use Cases
Multistage pumps are often used in oil pulling, chemical handling, seawater freshening, energy-making boiler water systems, and substance factories. Longgang’s LCD (BB3) horizontal split multi-stage centrifugal pump finds broad use in oil drilling, the chemical sector, the substance field, the coal substance area, and more.
Evaluate Longgang Multistage Pump Models
LDD(BB4)-High-Pressure Segmented Multi-stage Centrifugal Pump
The LDD(BB4) shows flat placement with a side split cover and blades set in one path. It backs flows from 5–1200 m³/h and is suitable for boiler water moving in energy sites. It contains improved steadying tools like drum-disc-drum builds that remove side pushes during work.
LCD(BB3)-Horizontal Split Multi-Stage Centrifugal Pump Advantages
The LCD series gives a length split cover with even blade placement that lessens leftover side force. It can manage liquids holding solid bits—perfect for hard work settings. With flow amounts from 10–1500 m³/h and heads up to 1600m, it is used widely in line transfer and power reclaim wheels.
Match Pump Type to System Design
Vertical vs Horizontal Configuration Selection
Upright pumps like LDTV (VS1) fit when the ground area is short or when drawing from deep holes. Flat pumps such as BB3/LCD give simpler upkeep reach and stronger output in steady spots.
Space, Installation, and Maintenance Considerations
If simple upkeep matters a lot—such as in fuel plants—flat split-cover plans let rod taking out without moving pipes. Upright setups might need special raising tools, but they spare useful ground area.
Consider Materials of Construction
Pick substances based on liquid harm level and heat. Longgang gives adjusted substance choices, including very low carbon double stainless steel, for strongly damaging liquids like hydrochloric acid or strong base. This setup guarantees lasting strength even in tough working states.
Analyze Efficiency and Energy Consumption
Output straight impacts running costs over periods. Longgang’s BB2 model has reached a checked fluid output mark of 90.5%, which stands 3.5% above the country’s top-level energy output rule. Choosing high-output types cuts energy use a lot over the years of work.
Review Reliability and Durability Factors
Pump steadiness relies on strong plan traits like self-steadying side force tools, improved support groups (ZH/ZQ), and exact making steps using CNC cutting centers at Longgang’s site covering over 8000m². Each item goes through strict checking on the basis able to withstand up to 30MPa force.
Confirm Certifications and Quality Standards
Make sure to match with global rules like API610/ISO13709 for process pumps used in fuel and gas fields. Longgang’s items get approved under ISO9001:2008 and API quality setups. The firm has also joined in setting country rules for the pump field.
