Understanding and Addressing Nozzle Loads in Pumping Systems / 1 Hour / January 27, 2026 / Webinar

Understanding and Addressing Nozzle Loads in Pumping Systems  

 Date: Tuesday, January 27, 2026 
Time: 1:00 PM - 2:00 PM ET 
PDH Credits: 1.0 

Overview: 

This webinar aims to address a critical issue: excessive nozzle loads applied to pumps, which have the potential to undermine the safety and reliability of pump operations. It reflects the ANSI/HI 9.6.2-2021 standard, titled 'Rotodynamic Pumps for Assessment of Applied Nozzle Loads.' The presentation will cover various factors contributing to nozzle loads, explore their impacts on pumps, and provide users with guidance on determining acceptable nozzle load levels. It will delve into the sources of casing nozzle loads, including piping dimensional changes, thermal growth, installation misalignment, and more. The presentation emphasizes the importance of accurate calculations, whether performed manually or through finite element analysis (FEA). Furthermore, it highlights the necessity of addressing mechanical, hydraulic, and thermal load sources along with example assessment calculations. Ultimately, this presentation aims to benefit pump OEMs, engineers, consultants, and purchasers by offering an in-depth overview of the standard's content, scope, and potential applications.

Learning Level – Intermediate: 

This level of training is designed for individuals who have some experience and knowledge in the subject matter. It builds upon the foundational concepts and expands the breadth and depth of understanding. Participants develop more advanced skills and competencies.

Audience:

Individuals looking gain in depth technical knowledge or those looking for a refresher, including pump system designers, engineers, technical support, test technicians and engineers, reliability and rotating equipment engineer, and experienced maintenance and operation personnel. 

Learning Objectives: 

• Understand the significance of nozzle loads on pump operation, recognizing their potential to compromise safety and reliability in pump systems.
• Identify the diverse sources of casing nozzle loads, including factors such as thermal growth, pressurization strain, and installation misalignment.
• Comprehend the effects of nozzle loads on pumps, encompassing nozzle stress, casing misalignment, and driver/pump misalignment leading to vibration and premature component failure.
• Differentiate between manual calculations and finite element analysis (FEA) methods for determining allowable nozzle loads, while acknowledging the role of assumptions in both approaches.
• Grasp the concept of hydraulic pressure reaction forces induced by axially flexible pipe couplings, such as rubber expansion joints, and the methods like thrust rods and tie-rods used to manage them.
• Recognize the importance of evaluating mechanical, hydraulic, and thermal load sources in minimizing piping loads to prevent excessive stresses on pump systems.
• Gain insight into the contents of the ANSI/HI 9.6.2-2021 standard, including nomenclature, material specifications, adjustment factors, maximum allowable nozzle loads, and example assessments of applied nozzle loads across various pump types.

Licensed Professional Engineers:

Continuing professional development is a vital component of the engineering licensure process. Most state licensing boards require continuing professional development as a condition for licensure and renewal of the license to practice engineering. The acceptance of continuing education as it applies to fulfillment of the state licensing requirements for professional designations is at the pleasure of the individual state licensing boards. It is the responsibility of the individual participants to be knowledgeable about their state requirements. Pre-approval of training providers and courses is not required by most state licensing boards, except for the following:

Florida Board of Professional Engineers

Pump Systems Matter is a board-approved continuing education provider for the Florida Board of Professional Engineers: License # CEA361.

New York State Board for Engineering, Land Surveying, and Geology

Pump Systems Matter is approved as a sponsor of continuing education for professional engineers in New York State: NYS Sponsor # 241.
