Application Scenarios of Dalian Chemical Pumps

Dalian Chemical Pumps

As China’s key equipment manufacturing and Northeast Asia chemical hub, Dalian’s pump industry boasts solid craftsmanship and tech, supplying petrochemical, fine chemical, basic chemical, environmental and new-energy sectors.

Petrochemical

Used in Dalian Petrochemical, Hengli Petrochemical and other refineries for atmospheric distillation, FCC and hydrocracking. High-pressure multistage centrifugal pumps handle hot pressurized hydrocarbon, sour crude and refined oil with hydrogen embrittlement resistance. Lined fluorine/alloy wet ends plus premium mechanical seals prevent acid leakage for uninterrupted refining.

Fine Chemical & Pharma Intermediates

Magnetic-drive and sanitary centrifugal pumps meet GMP standards for organic solvent, heat-sensitive and toxic acid-base fluid transfer in pesticide and pharmaceutical synthesis. Seal-free magnetic pumps eliminate leakage for pure product and safe production; wear-resistant impellers avoid crystal clogging and cut maintenance.

Basic Chemicals

Corrosion-resistant pumps with Hastelloy and high-silicon iron transfer 98% sulfuric acid, 32% caustic soda and liquid chlorine for chlor-alkali and sulfuric acid plants. Superior chlorine resistance cuts annual maintenance downtime by 30% in membrane electrolysis.

Environmental Protection

Rubber-lined slurry pumps transport gritty corrosive sludge and oily wastewater at chemical park sewage stations; also circulate limestone gypsum slurry for desulfurization and carry solvents for VOCs treatment.

New Energy

Leakproof magnetic and precision metering pumps deliver lithium iron phosphate slurry and electrolyte for lithium battery production under strict cleanliness rules.

Constant R&D expands pump applications, facilitating high-end and eco-friendly domestic chemical development.
