IHF Chemical Centrifugal Pump

Built as a robust chemical centrifugal pump, this unit is optimised for transferring and injecting corrosive chemicals like acids, alkalis, and oxidants. Its anti‑corrosion design not only meets the demanding standards of a chemical metering pump but also rivals the durability of top‑end chemical metering pumps. Consequently, it requires little upkeep under severe conditions, proving ideal for chemical, petrochemical, pharmaceutical, and wastewater treatment plants.

Application Scenarios

Chemical industry

Conveying strong corrosive media such as sulfuric acid, hydrochloric acid, sodium hydroxide, etc. It is suitable for liquid circulation and reactor feeding in chemical production.

Petroleum and metallurgy

Conveying petroleum products, high-temperature molten salt and other media, suitable for oil refineries, metallurgical plant process.

Pharmaceutical and Food

Conveying medicinal liquid and food grade liquid, conforming to sanitary standards, applicable to pharmaceutical and food processing industries.

Environmental protection and waste water treatment

Conveying industrial wastewater containing acid and alkali, suitable for medium conveying in wastewater treatment plants.

Product Advantages

High efficiency and energy saving

The efficiency of IH pump is 5% higher than traditional F-type pump on average, which is an energy-saving product promoted by the state.
Wide performance range, high efficiency, stable operation and low energy consumption.

Strong corrosion resistance

Suitable for strong acids, strong alkalis, and organic solvents, this unit combines the heavy‑duty durability of a chemical centrifugal pump with the dosing precision of a chemical metering pump — and it upholds the same stringent standards as premium chemical metering pumps. Whether you need to convey sulfuric acid, hydrochloric acid, or sodium hydroxide, it offers the resilience and accuracy required for aggressive fluids.

Wide range of medium temperature

-20℃ to 105℃ (standard type), under special working condition, it can reach -80℃ to +280℃ (need to adopt double end face seal cooling device).

Maintenance Access	Easy access to mechanical seal & impeller from outside	Need to lift out the whole pump for internal parts service
Application Scene	Long-distance transfer, high head, pipeline chemical delivery	Tank circulation, short cycle, small occupied floor space

FAQ for IHF Chemical Centrifugal Pump

Q1: Does the IHF chemical centrifugal pump support self‑priming operation?

A1: No, this horizontal fluorine‑lined pump has no self‑priming function. It needs full liquid priming before startup. Install a bottom valve if liquid level is below pump centerline. Dry‑run will damage the mechanical seal and fluoroplastic lining.

Q2: What media and temperature range are suitable for IHF pump?

A2: Its wetted parts are fluoroplastic‑lined for corrosive acid, alkali and salt solutions. No hard particles or fibers are allowed. Normal working temperature: -20℃ ~ 100℃. High‑temperature type is available for custom order. Abrasive media will speed up lining and seal wear.

Q3: What are main failure points and daily maintenance for IHF pump?

A3: The mechanical seal is the key wearing part, easily damaged by dry‑running, particles and medium crystallization. Regularly check leakage, temperature and vibration. Flush pump chamber after pumping crystallizable liquid. Drain residual liquid for long‑time storage. Never regulate flow by closing the suction valve.

The IHF Chemical Centrifugal Pump sets the benchmark for aggressive fluid handling with full fluoroplastic lining. As a corrosion-resistant chemical pump, it outperforms metallic chemical transfer pump units in acid/alkali resistance. Its centrifugal design ensures smooth transfer without pulsation – critical for precision chemical injection pump applications in dosing systems.
