This presentation focuses on the proper clearances, materials and installation process for centrifugal pump wear rings.

Equipping a pump test facility for variable speed operation can provide greater flexibility and expand opportunities to evaluate pump performance.

Emplear velocidad variable durante las pruebas puede brindar mayor flexibilidad y ampliar las oportunidades para evaluar el rendimiento de las bombas.

While highly effective for control, pulse width modulation introduces high-frequency transients that can compromise motor reliability if left unchecked.

A tilted or improperly sized oil standpipe can allow oil to migrate upward along the pipe’s wall when the motor is in operation, leading to leakage, loss of lubrication and potential bearing damage. This issue can be overlooked during assembly or inspection, but a few simple checks can prevent costly problems. 

A thoughtful succession plan—such as hiring a new manager one year before the retirement of the veteran employee—can turn the process of leadership transition into a positive, future-focused evolution.

Si bien es muy eficaz para el control, la PWM introduce transitorios de alta frecuencia que, si no se controlan, pueden comprometer la confiabilidad del motor.

This presentation provides a practical overview of applying both NFPA 70E (electrical safety) and 70B (electrical maintenance) standards to field and shop operations.

Often when we are dealing with three-phase squirrel cage motors we ask ourselves “Is there a standard or a rule of thumb for this motor characteristic?” The 10 characteristics that follow apply to conditions associated with motor starting as well as steady state operation. Examples are provided for each of the characteristics.

We all need friends, right? Isn’t the world a better place when you have someone to share it with? Electric motor shop leaders are no different. Peer groups have long been known as a means by which to advance collective goals and performance. EASA’s Roving Chief Executive (RCE) groups are exactly that - tailored to the executive, owner or general manager of electromechanical repair facilities.
