Describe the difference between a circulator with a steep pump curve and one with a flat pump curve. Which would be better for use in a multizone system using zone valves? Why?

Pump curves give the data about the ability of the pumps to produce the flow against a particular head.

Explanation:

Pump curves are basically information about a given siphon's capacity to deliver stream against certain head. At the point when you're perusing a bend, the siphon's stream rate will be on the top and base and its stature to push is on the sides.

In the system that the framework will have a filter which requires cleaning when the stream rate drops, the steep curve permits more weight drop at a given stream rate as we drop from the structure point.
