Chemical processing pumps are essential for industries handling corrosive, hazardous, or sensitive fluids, and they must adhere to specific standards to ensure safety and reliability. ANSI and ISO standards are two of the most widely recognized global standards governing chemical process pumps. These standards help ensure product standardization, improved reliability, and—most importantly—enhanced safety in industrial applications.
For companies looking for industry-leading chemical process pumps, Illinois Process Equipment (IPE) proudly offers a range of Flowserve and Peerless pumps that meet ANSI and ISO standards.
ANSI & ISO Standards Overview
The American National Standards Institute (ANSI) and the International Organization for Standardization (ISO) have set the benchmark for chemical process pumps. The most common standards include:
- ANSI/ASME B73.1: Defines requirements for horizontal end suction centrifugal pumps used in chemical processes. These pumps are commonly found in industries across North America.
- ANSI/ASME B73.3: Specifies requirements for sealless horizontal end suction centrifugal pumps.
- ISO 2858: Governs end-suction centrifugal pumps and specifies duty points, dimensions, and performance standards.
- ISO 5199 & ISO 15783: Establish technical specifications and guidelines for sealless rotodynamic pumps used in chemical processing.
Both standards ensure that pumps are durable, reliable, and safe for use in hazardous environments. However, the primary differences between ANSI and ISO pumps involve units of measurement, voltage frequency, and piping design.
ANSI Chemical Processing Pumps
ANSI chemical process pumps are primarily used in North America, where imperial units and 60 Hz motor speeds are standard. These pumps are designed to meet the ANSI/ASME B73.1 and B73.3 standards, ensuring compatibility with U.S. industry requirements. ANSI-compliant pumps typically use imperial fasteners and bolting, making them easier to integrate into existing systems for many U.S.-based industries.
ANSI pumps are often used for handling clean, non-hazardous fluids but can also be customized to handle more aggressive chemical services. The Peerless 8196 series and Flowserve Innomag brand are popular ANSI-compliant pumps known for their reliability and efficiency in handling a wide range of chemicals.
ISO Chemical Processing Pumps
ISO chemical processing pumps are more prevalent in Europe and Asia, where metric standards and 50 Hz motor speeds are the norm. ISO-compliant pumps follow standards such as ISO 2858, ISO 5199, and ISO 15783, ensuring compatibility with international systems.
ISO pumps offer excellent performance for chemical processing applications and are widely used in industries that require robust and versatile pumping solutions. These pumps also feature ISO/DIN flanges, making them suitable for piping systems built to international specifications.
Key Pump Offerings for Specific Applications
Both ANSI and ISO chemical process pumps are available in various configurations, with the primary distinctions being sealed versus sealless (magnetic drive), metallic versus non-metallic construction, and single versus dual containment systems. Here are some key pump offerings based on their applications:
- Water and Non-Toxic Fluids: The Flowserve INNOMAG TB-Mag with metallic casing or the Peerless 8196 with a single mechanical seal are ideal for handling non-hazardous services.
- Aggressive Chemical Services: For highly corrosive chemicals, the INNOMAG TB-Mag offers superior resistance, followed by the Peerless 8196 with a single or double seal.
- Critical, Toxic, and Hazardous Services: The INNOMAG TB-Mag mag drive is the best choice for hazardous environments requiring dual containment, ensuring safety and reliability.
