Select models use a special Hi-Temp seals that permits a short duration run-dry operation, but the pumps are not intended for extended time periods without liquid. The Hi-Temp seals were specifically designed for extended seal life while pumping water up to 210 F. Select Models including 270, 3CP, 310S, 5CP, 45, 55 are available with these special seals. They are numbered with a .3000 or .3400 added to the standard model number. Ask our technical team for assistance in selecting the correct pump. |
