Specific Speed and Attainable Pump Efficiency for Rotodynamic Pumps

 Date: Thursday, September 25, 2025 

Time: 1:00 PM - 2:00 PM ET

  PDH Credits: 1.0 

Overview:

This webinar will examine pump specific speed and its role in standard rotodynamic pump calculations. As an index of pump performance, specific speed provides valuable insight into the hydraulic characteristics of a pump, helps define the Preferred Operating Region (POR), and provides guidance on the impeller type that yields optimal pump efficiency. Building on this foundation, the presentation will introduce methods for determining attainable pump efficiency in rotodynamic pumps. Factors influencing attainable efficiency include pump type, hydraulic design, rated flow, specific speed, pumped fluid properties, rotational speed, and other critical variables. This portion of the webinar is based on the HI 20.3 Guideline, Rotodynamic Pump Efficiency Prediction, which offers a structured approach to calculate attainable pump efficiency across a range of pump types, including slurry, solids-handling, paper stock, multistage between-bearing, ASME/API, vertically suspended, and double suction pumps.

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:

• Calculate specific speed and understand its relevance in rotodynamic pumps.
• Analyze how specific speed influences attainable efficiency.
• Evaluate the impact of pump type and hydraulic design on attainable pump efficiency.
• Identify key factors affecting efficiency, including surface roughness, impeller trimming, and pumped fluid characteristics.
• Use the HI 20.3 methodology to estimate attainable efficiency for various rotodynamic 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.

Pump Physical Modifications and the Effects on Hydraulic Performance 

 Date: Wednesday, December 17, 2025

Time: 1:00 PM - 2:00 PM ET

  PDH Credits: 1.0

Overview:

This presentation will provide engineers with an understanding of how physical pump modifications affect hydraulic performance in rotodynamic pumps. Engineers will gain comprehensive insights into trimming, underfilling, vane angle adjustments, and volute/casing modifications. We'll explore effects on various pump types, discuss wear ring clearances, and present case studies. By understanding how physical modifications to pumps impact hydraulic performance, attendees will be equipped to alter pump designs to better meet the customer’s needs.

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:

• Gain insight into the effects of impeller modifications, including traditional trimming techniques and their impacts on hydraulic performance in radial and mixed flow pumps, as well as the influence of underfilling on both the bottom and top sides of the impeller vanes.
• Explore the implications of impeller (propeller) vane angle adjustments specifically within the context of axial flow pumps and their effects on hydraulic performance.
• Develop an understanding of volute/casing modifications, particularly the outcomes of opening the throat area and the effects resulting from cutting back the cutwater or tongue.
• Comprehend the significance of impeller/casing wear ring clearances in rotodynamic pumps and distinguish between the effects of reducing and increasing running clearances on pump efficiency and performance.
• Acquire knowledge of how impeller vane angle adjustments in radial (centrifugal) pumps affect hydraulic performance.
