In the demanding field of chemical processing, there is no room for mistakes. Project engineers and plant managers often face serious operational dangers when they use non-API-certified centrifugal pumps. These dangers show up as major seal breakdowns, dangerous fluid escapes, and unexpected shutdowns. Such issues can cost a facility millions in lost output and environmental penalties. Regular pumps usually do not have the strong sealing setups needed to hold toxic or unstable substances. As a result, they lead to ongoing maintenance and safety checks.
Longgang Pump tackles these key industry challenges by offering carefully designed products that follow the strict API 682 guidelines. Founded in 2001, we specialize in making high-quality centrifugal pumps for the petrochemical, chemical, and water treatment areas. With more than 70 main patents and a focused research and development team, we aim to provide the dependability that major global brands expect.
The Critical Importance of API 682 Standards
The API 682 standard sets the bar for “Shaft Sealing Systems for Centrifugal and Rotary Pumps.” In chemical processing, the seal often fails first. Our systems, which stick to API 682, make sure that containment of risky materials is secure. This holds true whether you use a radial pump and axial pump setup. We achieve this through improved flush plans and backup containment methods.
Unlike the usual centrifugal and reciprocating pump comparison, where upkeep demands might differ, our API 610/682 approved centrifugal pumps are built for steady, long-running use. This approval is vital for reducing the chance of volatile organic compound (VOC) releases. Such releases worry today’s chemical producers the most.
Strategic Solutions: Radial Pump and Axial Pump Applications
Knowing when to use a radial pump and axial pump is key to improving plant hydraulics and safety. Longgang Pump offers a wide range of options to fit these exact flow and pressure needs.
Radial Dissection for High-Pressure Safety
Our LBD (BB2) Radial Dissection Chemical Process Centrifugal Pump is built for hot and high-pressure chemical fluids. The radially split design uses dependable metal spiral-wound gaskets. This makes it far safer than non-API options when moving poisonous or quick-to-vaporize liquids. The radial pump and axial pump differences stand out in the LBD’s centerline mounting. It stops heat growth from shifting the drive center. Such shifts often cause seal problems in chemical facilities.
Axial Split Designs for Large-Scale Transfer
For tasks that need large flow amounts, like taking in raw materials, our LAD (BB1) Axial Split Double Suction Centrifugal Pump gives outstanding steadiness. In this radial pump and axial pump choice, the axial split works best because of its simple upkeep. You can check the rotor without removing suction or discharge pipes. This setup cuts down the time for repairs. It directly fixes the issue of work stoppages.
Performance Comparison: Centrifugal and Reciprocating Pump
In the chemical sector, the discussion about centrifugal and reciprocating pump systems usually focuses on flow steadiness. Reciprocating pumps do well at high-pressure dosing. However, centrifugal pumps serve as the go-to choice for large-volume, even transport.
Longgang’s centrifugal pumps provide a smoother flow pattern. They also have much less shaking than a centrifugal and reciprocating pump arrangement. For instance, our LBD (BB2) series includes a double volute for outlets over 80mm. This balances side forces and lengthens the life of API 682 seals. As a result, the pump acts as a trustworthy tool, not an upkeep burden.
Proven Success in Complex Chemical Environments
Our standing as a top maker comes from actual results in some of the toughest industry projects.
Case Study 1: 300,000 Tons/Year Epoxy Propane Project
In a major deal with Lihuayi Weiyuan Chemical , Longgang Pump supplied essential pumping tools for their Direct Oxidation Method Epoxy Propane Project. The work needed advanced centrifugal pumps to manage tricky chemical reactions without risk. Our skill in providing API-matching parts helped complete this 3.53 billion yuan project successfully.
Case Study 2: CO2 Long-Distance Transportation
In the Qilu Petrochemical – Shengli Oilfield Million Tons CCUS Project, we supplied a self-balancing CO2 booster pump with full local production. The liquid CO2 posed issues like poor lubrication and quick turning to gas. We used the centrifugal principle and fine-tuned the API 682 sealing setup. This fixed the steadiness and output problems that often trouble high-pressure tasks like these.

FAQ
Q: Why is API 682 essential for “sealless” levels of safety in chemical pumps?
A: API 682 offers standard, strong sealing fixes that stop hazardous fluid leaks. It ensures top containment for centrifugal pumps.
Q: How do I decide between a radial pump and an axial pump for my facility?
A: Radial pumps (like LBD/BB2) suit high-heat/pressure jobs. Axial split pumps (like LAD/BB1) fit high-flow needs and simple fixes.
Q: What makes your centrifugal pumps more efficient than a typical reciprocating pump?
A: Our centrifugal pumps deliver nonstop flow. Their hydraulic output reaches up to 90.5%. This cuts energy use a lot in big chemical shipping.
Q: Can your pumps handle highly corrosive media?
A: Yes, we create pumps with special metals like super-low carbon duplex stainless steel. These stand up to sulfuric and hydrochloric acids.
