The IHF Series Single-Stage Single-Suction Fluoroplastic Alloy Chemical Centrifugal Pump (IHF Centrifugal Pump) is designed and manufactured to international standards, integrating cutting-edge non-metallic pump technology. The pump casing is constructed with a metal shell lined with perfluoroethylene propylene (F46). The pump cover, impeller, and shaft sleeve feature metal inserts encapsulated in fluoroplastic through a sintering and pressing method. The external bellows mechanical seal is designed with a stationary ring made from 99.9% alumina ceramic (or silicon carbide) and a rotating ring made from PTFE filler material, ensuring excellent corrosion resistance, wear, and superior sealing performance.

Both the pump's inlet and outlet are reinforced with cast steel to improve its pressure resistance. The IHF centrifugal pump is highly regarded in practical use for its excellent corrosion and wear resistance, high-temperature tolerance, durability, high mechanical strength, and smooth operation. The pump features a well-designed structure that promotes reliable sealing, easy maintenance, and long service life, all while minimizing downtime and reducing the technical expertise required for upkeep.

Manufactured in compliance with ISO2858 and HG/T3183 standards, this pump’s interface dimensions align with other chemical pump models such as IH, CZ, and more, ensuring compatibility, high efficiency, and minimal vibration.

The IHF series centrifugal pumps are widely used in various industries, including biopharmaceuticals, petrochemicals, mining metallurgy, textile printing and dyeing, power generation, food processing, papermaking, electroplating, wastewater treatment, flue gas treatment, new energy, and new materials.

The IHF series pumps typically feature a single-end external WB2 mechanical seal. The silicon carbide mechanical seal ring is lightweight and has a low coefficient of thermal expansion, high hardness, excellent high-temperature strength, good dimensional stability at elevated temperatures, strong corrosion resistance, high elasticity modulus, and an extended service life.

Customization options are available for the IHF series pumps, and the mechanical seal can be tailored to meet the specific requirements of different working conditions. For handling corrosive media with crystallization or solid particles, a double-end mechanical seal with water flushing can be chosen.

The bearing box components of the IHF pumps utilize grease lubrication, preventing oil leakage, bearing slippage, excessive temperature rise, and bearing damage.

The simple structure of the IHF series pumps makes maintenance straightforward, significantly reducing the technical skills needed from maintenance personnel and simplifying disassembly and repair.

Applications:
Fields of Use: The IHF centrifugal pump is widely utilized across various industries, including environmental protection, petroleum, chemicals, food, biopharmaceuticals, power generation, metallurgy, aerospace, and more. It is particularly suitable for applications in refineries, ethylene plants, natural gas processing plants, chemical plants, pharmaceutical factories, nuclear fuel plants, nuclear power plants, and other industrial sectors.

Product Applications: The corrosion and wear resistance of the IHF centrifugal pump have been proven through extensive practical use. Some key applications include:

Transporting corrosive media in chemical production.

Chlorine wastewater treatment and acid addition in ion membrane caustic soda processes (widely used in domestic ion membrane caustic soda plants).

Electrolyte transport in non-ferrous metal smelting.

Acid washing processes in automobile manufacturing.

Pharmaceutical, petrochemical, power, electroplating, dyeing, pesticide, papermaking, food, and textile industries.

Long-term transportation of concentrated sulfuric acid, hydrochloric acid, hydrofluoric acid, nitric acid, aqua regia, strong alkalis, strong oxidants, organic solvents, reducing agents, and other highly corrosive media at temperatures ranging from -20°C to 150°C without any damage. This makes it one of the most popular choices for users in such industries.

Materials:
The pump casing is crafted from a metal shell lined with perfluoroethylene propylene (F46, PFA), while the pump cover and impeller are made by encapsulating metal inserts with fluoroplastic through a sintering and pressing process. The advanced external bellows mechanical seal is used for the shaft, with the stationary ring made from alumina ceramic (or silicon carbide), and the rotating ring made from PTFE filler material, providing superior corrosion and abrasion resistance. The inlet and outlet are reinforced with cast steel, significantly enhancing the pump's tolerance to both temperature and pressure. If required, custom designs and manufacturing options are available to meet specific operational conditions.

Application Fields
Biological medicine, petrochemical, mining, metallurgy, textile printing and dyeing, electricity, food, papermaking, electroplating, sewage treatment, flue
gas treatment, new energy, new materials, and other industries.

Pump Usage
Conveying different concentrations of sulfuric acid, hydrochloric acid, nitric acid, aqua regia, hydrofluoric acid, strong alkali, strong oxidizer, reductant, and strong corrosive medium such as chlorine ion. Can be resistant to all stainless steel to resist corrosion medium, instead of the expensive titanium alloy, money.

Design Instruction
IHF single-stage single-suction horizontal fluorine plastic centrifugal pump is according to the international standard and combined with a non-metallic pump design and manufacturing process. The pump body adopts a metal shell lining fee (F46, PFA), pump cover, impeller, and shaft sleeve are fluorine plastic with metal insert outsourcing whole sintering suppression and become, shaft seal mounted outside using advanced bellows mechanical seal, static choose 99.9% alumina or silicon carbide rings, a ring with four fluorine filling materials, its excellent corrosion resistant seal. Import and export of pump adopts cast steel reinforcement, in order to enhance the bearing gentle pressure on the performance of the pump.
