Why Reliable High-Pressure Pumps Are Critical for Petrochemical Success
The Demands of Modern Petrochemical Cracking Petrochemical cracking processes form the core of today’s chemical manufacturing. They change hydrocarbon raw materials into useful items like ethylene. These tasks require strong dependability and accuracy in handling fluids. This holds especially for ethylene feed lines that work at very cold temperatures and strong pressures. The ethylene feed […]
Reliable Fluid Handling in Harsh Environments How Longgang’s VS6 Pumps Outperform Traditional Models
Harsh Conditions in Industrial Fluid Handling Industrial fluid handling faces tough situations with rough and damaging liquids that put heavy stress on pumping gear. In areas like mining, metallurgy, and chemical wastewater treatment, these liquids often carry solid bits, harsh chemicals, or a mix of both. Such rough working setups speed up damage to the […]

Why OH1 Cantilever Pumps Are the Smarter Choice for Corrosive and Abrasive Fluid Transfer
Challenges in Transferring Aggressive Media Moving aggressive or corrosive fluids like corrosive acids, abrasive, high-solids slurries, and chemicals that form crystals brings specific problems in daily operations. These materials wear out standard pump parts much faster. Seals on the shaft, bearings, and inner walls break down rapidly from chemical damage or physical grinding. When crystals […]
Safe Chemical Processing Starts with the Right Pump: API Standards, Sealless Technology, and the LBD BB2 Advantage
The Challenge of Leakage in Chemical Processing In chemical processing plants, moving dangerous materials like acids, solvents, and harmful waste products safely ranks as a top concern. A small leak from a pump can cause serious problems. These might include injuries to workers or damage to the surroundings. Standard centrifugal pumps usually depend on mechanical […]
Protecting HPPO Catalysts Starts with the Right Pump Design
Why Catalyst Integrity Matters In the making of epoxy propane through the hydrogen peroxide direct oxidation process, catalyst performance stands as the key to smooth running. In the hydrogen peroxide direct oxidation (HPPO) process, highly sensitive titanium-based catalysts, such as TS-1 molecular sieves, are widely used for their excellent selectivity and efficiency. Yet, their high […]
Building Long MTBF and Lower TCO with Horizontal Split Multi-Stage Centrifugal Pumps
What is MTBF Mean Time Between Failures (MTBF) serves as a key measure of reliability in managing industrial gear. It represents the average operating time between inherent failures of a repairable system under normal operating conditions. A larger MTBF points to stronger dependability and fewer surprise stops, which matters a lot in fields like petrochemical […]
