Chemical pumps handle corrosive, aggressive, and chemically reactive liquids. IH series (SS304/SS316L): mild chemicals, dilute acids and alkalis to 80°C. IHF fluoroplastic-lined: strong acids (sulfuric, hydrochloric, hydrofluoric), strong alkalis and oxidising agents to 100°C. Flow 3.5–400 m³/h, head 4.5–125 m. Always confirm chemical compatibility with the specific wetted materials before specifying.
| Parameter | Value |
| Flow Rate | 3.5–400 m³/h |
| Head | 4.5–125 m |
| Temperature | -20°C to 100°C |
| IH Material | SS304 / SS316L — mild chemicals, dilute acids |
| IHF Material | PTFE / FEP / PFA lined — strong acids, alkalis, oxidisers |
| Seal | Mechanical seal (single or double) |
When should I choose IHF (fluoroplastic-lined) over IH (stainless)?
Choose IHF when the liquid is a strong mineral acid (H₂SO₄, HCl, HF, HNO₃), a strong alkali, an oxidising agent, or any medium that attacks SS316L. IH stainless is sufficient for dilute acids, weak alkalis, salt solutions and mild chemicals. Always verify concentration and temperature against the fluoroplastic compatibility chart.
IHF flurorplastic centrifugal pump is manufactured based on international standards and combined with non-metallic pump technology. Its pump body is made of metal casing lined with PTFE propylene, while the pump cover, impeller and liner plate are made of metal inserts and sintered and pressed fluoroplastics. Meanwhile, the shaft seal adopts external advanced bellows mechanical seal, the static ring adopts 99.9% alumina ceramics (or silicon nitride), and the dynamic ring adopts PTFE filling material, which has excellent corrosion and wear resistance.
IHF fluoine plastic centrifugal pumps finds application in the transfer of chemically corrosive media and electrolytes used in non-ferrous metal smelting, while also serving in automotive manufacturing processes such as acid baths. As such, they are the ideal choice for handling corrosive media such as strong alkalis, hydrochloric acid, hydrofluoric acid, nitric acid, and strong oxidizing agents.
- The shaft seal adopts advanced externally mounted bellows mechanical seal, and the grinding dynamic and static rings are made of world advanced SSIC industrial ceramics, and other materials can also be used to grind materials according to the user's special working conditions.
- It is designed and manufactured in accordance with international standards, so that its performance, rated performance points and dimensions are equivalent to the relevant international and national standards.
- The body and cover are made of metal matrix lined with fluoroplastic, and the impeller is formed on metal inserts by special molds of fluoroplastic alloy.

How do I select a chemical pump?
Start with chemical name and concentration, temperature, flow, pressure or head, solids content and required materials and seal arrangement.
What materials are available for corrosive liquids?
The site lists SS304/316L and PTFE-lined configurations. Material compatibility must be confirmed against the exact chemical and concentration.
Can an IHF pump handle strong acids and alkalis?
PTFE-lined IHF configurations are intended for corrosive service, but final compatibility must be checked for the specific chemical, concentration and temperature.
