random pump

long time reader, first time poster

ive been perusing mcmaster-carr site and i came upon their magnetic pumps. anyone ever thought about giving these a try (specifically....parts #9930K41 and #9930K63). the thing that worries me is that neither the rpm nor decibel rating is given but their design is similar to the iwakis. i'm assuming their shutoff,ft rating is the head.

got a link ?

At first glance they look ok, but the head/horse power ratio is far less than optimum. A whole lotte pump heat for relatively little water movement.

They look like knok offs of the Iwaki RLXT line.
