In the challenging world of advanced machinery production, the reliability of fluid handling setups serves as the core of industrial advancement. For many years, the “weak spot” in vital core methods for robust pumping arrangements compelled numerous companies to depend on costly, delayed overseas purchases.
Nowadays, Longgang Pump is changing this story. As a national “specialized, refined, and innovative” small giant company, Longgang Pump is overcoming overseas dominance via self-reliant research and bold machinery improvements, which guarantee that the essential “lifelines” in the petrochemical and ocean engineering fields stay strong and effective.
Addressing the Pain Points: Efficiency, Vibration, and Maintenance
For factory supervisors and upkeep specialists in the oil and chemical fields, three ongoing issues shape the life cycle of a pump: working efficiency, physical shaking, and the rising expense of upkeep. Conventional pumps frequently face too much axial thrust and seal breakdowns during fast operation. As a result, this causes unexpected stoppages that may lead to millions in production losses.
Longgang Pump has tackled these problems directly. Through the Shandong Provincial Engineering Research Center for Heavy-Duty Petrochemical Centrifugal Pumps, we employ data gathering and instant review to refine each molding and shaping process. Our BB3 heavy-duty stripping tower bottom pump stands as a key example of this approach. When compared to famous global brands, our BB3 series delivers:
- 2% Higher Efficiency:This cuts energy use right away.
- Superior Stability:It keeps vibration at just 5mm/s.
- Economic Optimization:This lowers total equipment running and upkeep expenses by 4%.
By fixing the main reasons for pump housing shaking and seal issues, Longgang Pump offers a fix where quick running does not mean frequent repairs.
Pioneering Solutions for Offshore Floating Platforms
Shifting from ground-based tasks to the “deep sea area” creates a tough setting for fluid devices. In sea engineering, centrifugal pumps for offshore floating platforms must deal with seawater’s tricky makeup. High levels of chloride ions cause serious metal rust and grinding damage, which might weaken the strength of high-pressure water injection pumps.
Reducing Chloride Ion and Corrosion Impacts
Our development group targets reducing chloride ions and corrosion specifically, using cutting-edge material knowledge. For our high-pressure water injection pumps, we have created unique alloy substances and super-low carbon duplex stainless steels that show outstanding defense against harsh fluids.
The Technological Leap of 2026
To meet the strict needs of sea engineering, Longgang Pump started a major tech upgrade. Early in 2026, we brought online a fresh high-precision five-axis linkage machining center and a closed-loop high-flow test bench that achieves Level 1 precision.
Our ongoing work with the Shengli Oilfield offshore platform proves this advancement. We are completing the supply of the initial fully home-made, self-managed high-pressure water injection pump for sea platforms. This success means that sea operators no longer need to rely on outside vendors for key water injection and pressure upkeep jobs.
Technical Highlights: The BB3 Series (LCD Model)
The BB3 (LCD) series marks our top horizontal, multi-stage centrifugal pump, built strictly to the API610 11th edition standard.
Design and Performance Parameters
| Flow (Q) | 10 to 1500 m³/h |
| Head (H) | Up to 1600 m |
| Working Pressure (P) | Up to 25 MPa |
| Operating Temperature (T) | -60°C to +200°C |
Core Engineering Advantages
Symmetrical Impeller Arrangement: The back-to-back impeller setup ensures minimal leftover axial forces, so it removes the need for intricate balancing devices that often break down in older setups.
Axial Split Casing: The single-casing, axial split structure permits checking and swapping of bearings and mechanical seals without shifting the inlet or outlet pipes, which greatly lowers maintenance costs and cuts stoppage time.
Advanced Simulation: By using PUMPCAD and CFD (Computational Fluid Dynamics), we examine inside flow paths and tension-strain links to lessen operation risks before the pump even arrives at the plant.
Applications and Proven Success
Longgang Pump’s answers go beyond ideas; they drive large industrial groups.
1. The Million-Ton CCUS Project
Our CO2 booster pumps (Capacity 125m³/h @800m) play a key role in the “Qilu Petrochemical – Shengli Oilfield Million Tons CCUS Project”. We managed to swap out foreign gear with fully local parts, addressing the difficulties of moving liquid CO2, which tends to vaporize easily and offers poor lubrication.
2. High-Pressure Boiler Feed Water
In the Qingdao Refinery Liquefied Gas Safety Improvement project, our high-pressure self-balancing boiler feed water pumps deliver steady performance in vital areas where dependability matters most.
3. Coal and Petrochemical Industry
From coal conversion to big ethylene plants (such as the 1.2 million tons yearly ethylene effort in Tianjin), our pumps manage tough tasks like quenching oil flow, lean/rich fluid movement, and stripping tower bottom output.
Future Focus: Intelligent and Digitalized Systems
The pump sector’s future rests in moving from mechanical parts to intelligent and digitalized setups. Longgang Pump is now adding electronic test signal capture and shaking assessment tools (CRAS) to our devices, so they offer live oversight.
Our aim is to grow from a pump maker into a world-leading special pump system solution provider. With smart sensors included, we can foresee upkeep requirements before problems arise, which further reduces maintenance costs and boosts safety in sea and petrochemical work.
Longgang Pump stays dedicated to the growth route of “technology-led business and innovation-led progress”. Be it on-land chemical handling or the harsh settings of sea platforms, our work makes sure that your tasks run smoothly, reliably, and affordably.
