Rick Blunt, Facilities Maintenance Team Leader at International Rectifier Corporation writes:

We purchased these pumps on the recommendation of our local vendor, who said that I would be very pleased with the performance.  Upon delivery of the units I was concerned about their ability to do the task because they had a smaller footprint and lower power requirements.  These concerns were short lived however, because once we got them started up we found that not only did they exceed the design criteria; they did it at a much lower motor speed, with less noise, and less operating vibration.  A wonderful pump, highly recommended.”
