Hydraulic Institute (HI) has announced the kick-off of their Spring 2009 Webinar Pump Knowledge Series titled “Motors & VFDs”. Hydraulic Institute is now offering live presentations by subject matter experts delivered right to a pump professional’s desktop – home or office. Participants will be led by and have access to industry-leading experts in a non-commercial educational forum.

The courses were developed in conjunction with and are presented by members of the Hydraulic Institute Drives & Controls Standards Committee who have researched and written extensively on the topic of motors and VFDs during the development of the ANSI/HI pump standards.

All HI webinar participants earn HI professional development hours. Registration for the HI webinars is per connection, and registrants may have as many people in the room as they would like to participate in the session.
