coking industry pump
In the coking industry, media such as ammonia water, phenol-ammonia wastewater, tar-containing slurry, desulfurization liquid, and high-temperature wash water are generated during coke oven gas washing, quenching, and wastewater treatment processes. These fluids are typically highly corrosive, contain a high level of solids, and operate at elevated temperatures, which can easily cause pump corrosion, abrasion, leakage, and frequent shutdowns for maintenance. To address these issues, these factors should be fully considered during pump selection to solve the problems at their root.
Changyu Pump is a professional pump manufacturer in china. We supply corrosion-resistant pumps, abrasion-resistant slurry pumps, vertical cantilever pumps, magnetic drive sealless pumps, and diaphragm pumps. We can also provide customized pump solutions based on your actual operating conditions.

Coking Industry Pump Solutions
Ammonia Water Circulation
Recommended Pump Type: Stainless Steel Centrifugal Pump
Reason: Our CYH series centrifugal chemical pumps feature wetted parts made from corrosion-resistant metals such as 304, 316, or 316L stainless steel to meet diverse operational requirements. They are widely used for pumping acids, alkalis, corrosive substances, toxic materials, and various other media.
Desulfurization Liquid Transfer
Recommended pump type: Desulfurization Slurry Pump
Reason: Our UHB series slurry pumps feature a cantilevered single-stage centrifugal design, equipped with a semi-open impeller and cartridge mechanical seal. Constructed from imported UHMWPE material integrated through high-temperature sintering, this material exhibits exceptional wear and corrosion resistance. Consequently, these pumps are specifically engineered for conveying corrosive media containing solids or crystalline particles.
Tar-containing Wastewater Pumping
Recommended pump type: Air-Operated Diaphragm Pump
Reason: Our BFQ series air-operated double diaphragm pump, also known as a chemical diaphragm pump, features high flow rates, strong self-priming capabilities, and compatibility with multiple materials. Designed specifically for corrosive, abrasive, and volatile fluids, they are suitable for diverse industrial applications.
Wastewater Treatment and Discharge
Recommended pump type: Corrosion Resistant Centrifugal Pump
Reason: Our industrial pump utilizes imported FEP/PTFE materials and can also be configured with high-temperature-resistant PFA material based on the temperature of the medium. Both the pump casing and wetted components are optimized for highly corrosive fluids. The seal can be equipped with a K-type dynamic seal, ensuring stable, leak-free operation when conveying corrosive fluids.
Application in Coking Industry
Coking operations generate corrosive and abrasive liquids, such as ammonia water, phenol-containing wastewater, tar-containing slurry, and high-temperature wash water. These media are highly corrosive, severely abrasive, and contain a high level of solids, which can easily cause pump corrosion, leakage, or clogging, so pump performance directly determines the efficiency of coking plant operations.
Pompe Changyu provides corrosion-resistant centrifugal pumps, abrasion-resistant slurry pumps, vertical cantilever pumps, magnetic drive pumps, and diaphragm pumps, and can also offer customized production based on your actual coking plant operating conditions.
Ammonia Water Circulation
The ammonia water in this operating condition is highly corrosive and circulates continuously, making the pump body susceptible to corrosion and leakage.
Advantages: Our pump’s wetted parts are constructed from 304/316/316L stainless steel, offering superior corrosion resistance. This material is suitable for acids, alkalis, ammonia water, and other corrosive chemical media, ensuring stable and reliable pumping operation.
Desulfurization Liquid Transfer
The desulfurization liquid contains sulfides and solid particles, which can easily cause pump wear and corrosion.
Advantages: Our pumps feature a cantilevered single-stage centrifugal design, constructed from high-temperature sintered UHMWPE material. They offer exceptional wear and corrosion resistance, making them ideal for pumping corrosive media containing solids or crystals.
Tar-containing Wastewater Pumping
High-viscosity media containing oil and suspended solids can easily clog the pump.
Advantages: Our diaphragm pumps deliver high flow rates with strong self-priming capability, compatible with multiple materials, and suitable for tar wastewater and high-viscosity industrial liquids.
Wastewater Treatment and Discharge
Wastewater containing corrosive chemicals and fine particles can cause pump wear or leakage.
Advantages: Our industrial pumps feature pump bodies and wetted components constructed from highly corrosion-resistant materials, making them suitable for pumping highly corrosive, abrasive, and high-temperature media.
