The Taco 007 circulator pumps are on their way of consistent improvement over the years. There is a long series of models launched by Taco and each one has some salient features over the previous model.
Each Taco 007 pump has some specific features; the customers must consider all of them before going to buy the best one according to their requirements. These features include the construction material of the pump, its dimensions, working flow parameters and the pressure under which taco pumps can operate and so on.
Taco pumps are available in cast iron, stainless steel and bronze. The cast iron flanged Taco 007 is more popular than the other two in the closed loop hydronic applications. The bronze water circulator pumps and stainless steel water pumps are more effective with open loop circuit systems.
