Many different types of pumps can be used with the selection depending on the work that needs to be done. One type would be used for transferring water from a well to a tower; another would be better suited for pumping sludge containing a lime byproduct from a softening plant; still another would be used for feeding a chemical into the water for treatment. Among the considerations in selecting a pump are the maximum flow needed in gallons per minute (gpm), the head it needs to pump against, and the accuracy needed for flow control.

How does an Aquatec permeate pump work?
It functions by storing the hydro power from the RO unit's drain water stream and using this energy to force product water (permeate) into the RO unit's storage tank. It frees the reverse osmosis unit from the need to contend with back pressure from the air-pressurized storage tank. The result is that the RO tank fills faster and the unit uses less drain water and produces better quality water.
