Features: The pump adopts centrifugal impeller and has large capacity, work with low noise. Its design keeps pump in working low temperature. For instance, the body and motor are separated partly, which is better for circulative boosting hot water. Main use: This pump absolutely solves the lit fire properly of shower owing to the lower pressure and unreliable pressure. When the tap water is of low pressure, the pump can boost pressure. It can alse boost pressure for solar water heaters, boost pressure and circulate water for industrial equipments, and increase oxygen for rearing ponds and fish tanks.
