Pond Pumps
A Hy-drive pump is a cross between a direct drive and a
magnetic drive pump. They are similar to the magnetic drive because the impeller
is turned by a magnet made of copper and steel, which allows a lower cost for
electricity compared to the direct drive. Asynchronous means that the pumps impeller
only turns one way.
Since the impeller is only able to turn one way it makes these
pumps very quiet, efficient and last a long time. The impeller is also slightly
curved like the direct drive pump. A curved impeller can increase the flow and the
head height. The maximum head height that they can produce is around 20’ of
head. However the flow can drop off
rapidly when it gets near the maximum height of head.
Most Hy-Drive pumps have a 2 to 3 year warranty. If you have a
head height that is around 10’ to 15’ and want more flow it would be more cost
effective to have two hy-drive pumps than one direct drive.
