Variable Speed Pumping 

 Date: Wednesday, February 11, 2026
Time: 1:00 PM - 2:00 PM ET 
PDH Credits: 1.0   

Overview:

This webinar covers the basics of variable speed pumping (VSP).Topics include pump curves, affinity rules, power consumption, pump and system curve interaction and a comparison of methods to vary the pump system operating point.  Several examples will illustrate the operation, cost, and energy-saving benefits of variable speed pumping. Participants will leave with a clear understanding of variable speed pumping, system hydraulics, and the associated benefits and limitations. 

Learning Level - Basic:

Basic level training is intended for individuals who are new to the subject matter. It introduces basic concepts, skills, and practices, enabling participants to gain a foundational understanding of the topic and develop basic competencies. 

Audience:

This course is intended for individuals with introductory knowledge of pump curves, system curves and the pump operating point, or those seeking a refresher, including pump system operators, maintenance personnel, pump system designers and owners, technical sales professionals, and engineers.

Learning Objectives:

Upon completion, learners should be able to: 

 Gain an understanding of how pump affinity rules affect performance curves for both rotodynamic and positive displacement pumps. 

• Apply the pump affinity rules to assess changes in pump performance. 

• Understand the effect of variable speed on the pump system operating point. 

• Evaluate methods for varying the pump system operating point and its impact on power and energy consumption.

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.
