Star Marine Depot carries a selection of various types of pumps such as centrifungal pumps. What is a centrifungal pump and how do centrifungal pumps work? These pumps use centrifugal force to discharge fluid into a pipe. Centrifungal pumps eliminate the conventional shaft seals found in most pumps. This means that there is no rotating seal to wear and allow the liquid being pumped to leak because of its “seal-less” design and can run fully submerged in water.
