Weil-Mclain AHE-45

Have an early 1990s Weil Mcalin AHE-45, series II, the circulator pump died. Replaced it with new one (Taco 005-EF1-2W). Now the boiler fires and runs, shuts off when satisfied, but will not circulate hot water. The pump seems to be running but HW does not circulate throughout system. This is the circulator pump with built-in mixing valve and car-radiator-like thermostat. Any ideas?
