How a webinar works

All EASA private webinars are live events in which the audio and video are streamed to your computer over the Internet. Prior to the program, you will receive a web link to join the meeting. 

The presentation portion of the webinar will last about 45 minutes, followed by about 15 minutes of questions and answers.

Requirements

  • Internet connection
  • Computer with audio input (microphone) and audio output (speakers) appropriate for your size group
  • TV or projector/screen

The Zoom webinar service EASA uses will ask to install a small plugin. Your computer must be configured to allow this in order to have full functionality. Please check with your IT department or company's security policy prior to scheduling a private webinar.

Private Webinars

EASA's private webinars are an inexpensive way to bring an EASA engineer into your service center, place of business or group meeting without incurring travel expenses or lost production time.

Pump Close Tolerance Fits

The repair of roto-dynamic pumps (pumps with centrifugal and axial flow impellers) requires that, as much as possible, the mechanical condition of the pump be returned to factory specifications. This presentation focusses on critical close fit tolerances and certain surface finish specifications. The best recommendation is always that factory tolerances be used. However, when those factory tolerances are simply not available and the pump must be repaired, service centers rely on general rules of thumb and experience to complete repairs. 

The following concerns will be reviewed: 

  • Rolling element bearings
  • Sleeve bearings (horizontal)
  • VTP bearings
  • Impeller-casing wear rings
  • Casing rabbets
  • VTP motor mounting flange runout and P-flange type motor bases
  • Throttle (throat) bushings
  • Impeller-shaft fit
  • Stage bushings

This summary of data, collected from various service centers, pump manufacturers, parts manufacturers and engineering resources, assembled in one resource, will be helpful to pump repair technicians, supervisors and engineers.

See the related recording and white paper "Pump Repair: Working with Close Tolerance Fits" that was presented at the EASA 2023 Convention.
