Pump Physical Modifications and the Effects on Hydraulic Performance
Date: December 5, 2023
Time: 1pm EST
PDH Credits: 1.0
This webinar will provide engineers with an understanding of how physical pump modifications affect hydraulic performance in rotodynamic pumps. Engineers will gain comprehensive insights into trimming, underfiling, 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 optimize pump designs and better meet the customer’s needs.
• 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 underfiling 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.

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 or professional licensing boards. It is the responsibility of the individual participants to be knowledgeable about their state requirements.
Licensed Professional Engineers
Continuing professional development is a vital component to 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. Pre-approval of training providers and courses are 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.
North Carolina Board of Examiners for Engineers and Surveyors
Pump Systems Matter is an approved continuing professional competency sponsor for the North Carolina Board of Examiners for Engineers and Surveyors: Sponsor # S-0523.
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.
