ISO2858 Chemical Pump for Transport of Corrosive Liquids

In the world of chemical processing, precision, reliability, and safety are critical. One of the most important components of any chemical handling system is the chemical pump — a machine designed to move corrosive liquids safely and efficiently. Among the many types of chemical pumps available, the ISO2858 chemical pump stands out as a globally recognized standard for performance and reliability.

What Is an ISO2858 Chemical Pump?

An ISO2858 chemical pump is a standardized end-suction centrifugal pump that conforms to the ISO 2858 international standard. This standard, issued by the International Organization for Standardization (ISO), defines the main dimensions, performance, and interchangeability of horizontal, single-stage, end-suction centrifugal pumps.

These pumps are typically used in industrial settings, particularly for the transport of corrosive or hazardous liquids in sectors like:

• Chemical processing

• Petrochemical industries

• Water treatment plants

• Pharmaceutical manufacturing

• Food and beverage industries

The goal of the ISO standard is to ensure that pumps from different manufacturers can be interchanged without requiring system redesigns. This is especially useful in industries where downtime can be costly and dangerous.

Why Use ISO2858 Chemical Pumps for Corrosive Liquids?

Corrosive liquids — such as acids, alkalis, solvents, and certain organic compounds — pose unique challenges. They can degrade materials over time, corrode metal surfaces, and lead to safety hazards or equipment failures. The ISO2858 chemical pump is specifically designed to meet these challenges due to the following advantages:

1. Standardized Performance

The ISO2858 standard ensures that every pump built to this specification meets a reliable flow rate and pressure range, ensuring consistent performance across applications.

2. Corrosion-Resistant Materials

ISO2858 pumps are typically constructed with high-grade stainless steel (such as 316L), fluoroplastics, PTFE, or other corrosion-resistant alloys. This helps extend the service life of the pump and protects it against aggressive chemicals.

3. Ease of Maintenance

The modular design of ISO2858 pumps simplifies maintenance and part replacement. This is crucial when handling dangerous fluids — fast and safe maintenance reduces exposure risks and downtime.

4. Interchangeability

Because the design is standardized, you can replace an ISO2858 chemical pump with another ISO2858-compliant pump from a different manufacturer — without needing to modify the piping system or motor base.

Key Features of ISO2858 Chemical Pumps

To better understand their suitability for corrosive liquids, let’s take a closer look at the core design features:

✔ Back Pull-Out Design

This allows the pump's rotating assembly (impeller, shaft, bearings, etc.) to be removed without disturbing the pipe connections. It simplifies maintenance, especially in hazardous chemical environments.

✔ End Suction, Single Stage

ISO2858 pumps are centrifugal single-stage pumps with a simple design and high reliability. The end suction configuration minimizes cavitation risks and supports steady flow rates.

✔ Sealing Options

For corrosive liquids, mechanical seals (especially double mechanical seals or cartridge seals) are commonly used to prevent leaks and protect the environment and operators.

✔ Non-Metallic Linings or Coatings

Some pumps come with non-metallic linings (such as rubber or plastic) or are fully constructed from non-metallic materials to enhance chemical resistance.

Typical Applications in Corrosive Liquid Handling

Because of their robust construction and standardized performance, ISO2858 chemical pumps are widely used in the following corrosive liquid applications:

Acid Transfer in Chemical Manufacturing

Sulfuric acid, hydrochloric acid, nitric acid, and phosphoric acid are all common in industrial processes. ISO2858 pumps made with compatible materials ensure safe and leak-free handling.

Alkali and Caustic Solutions

Caustic soda (NaOH), ammonia solutions, and sodium hypochlorite can be particularly aggressive to equipment. Pumps with PTFE components and special shaft seals are suitable for such applications.

Solvent Handling in Petrochemicals

Many organic solvents are volatile and flammable. ISO2858 pumps minimize leakage risks and can be equipped with explosion-proof motors for hazardous areas.

Pharmaceutical and Food Industries

Corrosive cleaning agents and aggressive additives are often part of sanitary processes. Using corrosion-resistant pumps ensures compliance with hygiene and safety regulations.

How to Choose the Right ISO2858 Chemical Pump

Choosing the correct ISO2858 pump for corrosive liquids involves careful consideration of several parameters:

1. Chemical Compatibility

Consult a chemical compatibility chart to match the pump materials (e.g., 316L stainless steel, PVDF, PTFE) with the liquid being handled.

2. Flow Rate and Head

Understand your system’s required flow rate (m³/h) and head (m) to size the pump correctly. Oversizing or undersizing can reduce efficiency or cause damage.

3. Temperature and Viscosity

Corrosive liquids at high temperatures or with high viscosity require special mechanical seals and motor configurations.

4. Sealing Requirements

Double mechanical seals, flushed seals, or magnetic drive designs may be necessary for highly volatile or toxic fluids.

5. Environment and Installation

Check if the pump will operate in an ATEX-rated (explosion-proof) area, outdoors, or submerged. These factors will affect motor type, coating, and housing design.
