REMEMBER MOST ALL MARINE WATER IS ABRASIVE AND AN ABRASIVE MARINE SEAL IS WORTH EVERY PENNY SINCE THE SERVICE LIFE IS INCOMPARABLE AND THE PAY BACK COMES WITH THE FIRST SEAL WEAR REPLACEMENT, IN SEAL COST AND INCONVENIENCE. For extreme service life Dolphin recommends always choosing abrasive proof seals for marine and sandy fresh water unless they are not available in the pump desired. Our Crane type stainless non abrasive marine water seals are produced for CLEAN marine seawater, they do not offer the longservice life of the Crane abrasive marine seal or the extreme service life of the Fringe Tech 3 seal, the Worlds best marine/reef pump is the Fringe Tech 4 seal. All aspects of this pump surpass seal less pumps. For maximum efficiency in electrical draw and service life pumping the harshest reef water the Diamond Series Type 4 pumps are the holy grail for the Reef Aquarium industry. Amp Masters are all silent and cool running.SECONDIS ENERGY CONSUMED.
