Well pumps are not normally considered to be water treatment equipment but they can have a great impact on both the quantity and quality of the water that is delivered from a well. While it seems obvious that an undersized pump will not deliver the desired amount of water at the desired pressure, it is less widely realized that an undersized pump may leave a "dead zone" in the lower portion of a well which can act as a harbour for bacteria. MacLellan Water Technology is able to specify the right pump for any pumping situation, including constant pressure pumping systems.
