API 675 and dosing pumps: the standard for reliable and accurate dosing

In many industrial processes, accurate liquid dosing plays a crucial role. Think of applications in the chemical industry, water treatment, oil & gas, and the pharmaceutical sector. To ensure consistency and reliability worldwide, dosing pumps are often designed and tested according to international standards. One of the most widely used guidelines for this is API 675.

In this blog, we explain what API 675 entails, why it is important for dosing pumps, and the benefits it offers for the process industry.

What is API 675?

API 675 is a standard from the American Petroleum Institute (API). This standard outlines the requirements for positive displacement pumps with variable stroke (plunger pumps and diaphragm pumps) used for precise dosing.

The standard covers, among other things:

• Dosing accuracy
• Stroke volume repeatability
• Pump reliability and lifespan
• Suitability for continuous operation in harsh process conditions

Thanks to this guideline, end users can be confident that a pump meeting API 675 performs consistently and reliably, even under harsh conditions.

Why is API 675 important for dosing pumps?

In dosing processes, even a small deviation can have significant consequences. For example:

• Over- or under-dosing of chemicals in water treatment
• Incorrect proportion of additives in oil and gas processes
• Risks of product deviations in the pharmaceutical industry

An API 675 dosing pump ensures that the pump:

1. Doses accurately, often within ±1% of the set capacity.
2. Performs consistently, stroke after stroke.
3. Is built robustly, with attention to safety and ease of maintenance.

This makes these pumps ideal for critical applications where errors are simply not acceptable.

Applications of API 675 dosing pumps

Dosing pumps that comply with API 675 are used worldwide in sectors where reliability and precision are paramount. Examples include:

• Oil & gas: injection of chemicals such as methanol or corrosion inhibitors.
• Water and wastewater treatment: precise dosing of disinfectants and coagulants.
• Chemical industry: blending additives or catalysts in production processes.
• Pharmaceuticals: controlled dosing of active ingredients during production.

Advantages of an API 675 dosing pump

Choosing a pump that meets API 675 offers several advantages:

• Reliable performance under harsh process conditions
• Long service life due to robust design
• Reduced operational risks through consistent accuracy
• International recognition, making pumps deployable worldwide
