In the petrochemical sector, picking the right gear for moving fluids plays a key role in the ongoing profits and safety of any facility. Plenty of sites still deal with old, inefficient machines. These cause steep energy use, regular breakdowns in mechanical seals, and too much shaking that endangers the building’s strength. Such problems often stem from not carefully fitting pump types to exact fluid needs.
Longgang Pump tackles these issues with strong, API-approved options. We started in 2001 and earned the title of a top “Gazelle Enterprise” in Shandong. Plus, we act as a trusted provider to big names like CNPC, Sinopec, and CNOOC.
The Strategic Importance of Efficiency in Fluid Transport
Running a petrochemical plant smoothly goes beyond just cutting power costs; it focuses on steady system performance. Pumps with poor efficiency create extra warmth and shaking, which speeds up damage to bearings and seals. At Longgang Pump, we apply modern tools for fluid design, such as PUMPCAD software and CFD three-dimensional fluid simulation, to improve how fluids move. Our own high-efficiency centrifugal pumps reach a confirmed best point of 90.5% in hydraulic work, which beats China’s national top energy standard by 3.5%.
Identifying the Ideal Single-Stage and Multistage Pump
For company leaders, a vital task involves figuring out the right pressure and flow needs by deciding on a single-stage or multistage pump setup.
- Single Stage Solutions:These work well for tasks needing lots of flow at medium heights, like in refinery units for air and vacuum. Our LZA(OH1) and LZE(OH2) cantilever pumps provide a sturdy, easy-to-remove setup that simplifies upkeep.
- Multistage Excellence:If the job calls for strong pressure output, such as feeding boilers or sending fluids over long pipes, the choice of single-stage and multistage pumps should favor our LCD(BB3) or LDD(BB4) Our LCD(BB3) horizontal split multi-stage pump uses a balanced impeller layout, which naturally offsets axial pushes and keeps things steady even in tough spots.
The Power of the BB1 Double Suction Pump in Large-Scale Logistics
When it comes to shifting large volumes, like in crude oil lines , the BB1 double suction pump stands out as a top pick for steadiness and easy fixes.
Structural Advantages of the LAD(BB1) Series
The LAD(BB1) axial split double suction pump follows API 610 11th edition rules. Its double-suction impeller lets fluid come in from both ends, so it naturally cuts down on axial pushes and lowers the Net Positive Suction Head (NPSH) needs. Because of this, the BB1 double suction pump suits high-flow jobs where avoiding cavitation matters. Moreover, the axial split casing lets workers check or swap the full rotor, bearings, and seals without touching the input or output pipes, which cuts repair time a lot.
Innovation in the China Axial Pump Market
As a main player, Longgang Pump has raised the bar in the Chinese axial pump field by blending exact building methods with global control practices. Our China axial pump items, including the LAD line, add a double volute casing in bigger sizes to cut down on side pressure waves and shaking. We stress firm shaft builds that run far under the first key speed, so each China axial pump we send out fits the top dependability needs in the worldwide petrochemical world.
Technical Highlights: Engineering for Reliability
Those who pick Longgang Pump gain from our full setup for research and building.
- Precision Machining:Our shop has CNC gantry machining centers and exact round grinders to make sure every part of the BB1 double suction pump, single stage, and multistage pump hits tight measures.
- Testing Rigor:Our test setup hits Level 1 accuracy and handles power up to 4000 kW, along with pressures up to 30 MPa. This system runs checks on fluid output, cavitation tests, and long-run trials to spot and fix all output risks.
- Material Science:We go beyond basic stuff and focus on super-low carbon duplex stainless steel pumps that stand up to sharp, eating fluids like weak sulfuric acid and caustic soda.
Application Studies: Proving Performance
Our skill in tech shows through wins in big industrial jobs.
Case Study 1: Yulong Island Refining and Chemical Integration
In the 2023 Yulong Island Refining and Chemical Integration Project (Phase I), Longgang Pump supplied the feed oil circulation pump. We used a BB5-lined BB3 build to move hot oil at high temperatures, making sure the single-stage and multistage pump needs got met with top-line steadiness and heat toughness.
Case Study 2: Million Tons CCUS Project
For the Qilu Petrochemical – Shengli Oilfield Million Tons CCUS Project, we hit 100% localization on the CO2 pipeline booster pump. Since liquid CO2 tends to turn to gas and lacks good slip, we made a self-balancing shape and mixed drag-cut tech. This step swapped out foreign parts and kept steady work at 10.0 MPa, showing how a Chinese axial pump maker can lead in top global advances.
