Constant curve

When there is a demand for constant flow and constant head, a speed-controlled pump can replace a throttle valve for adjusting the flow.

The speed can be adjusted between 25 % and 100 %.

This feature is especially beneficial in:

  • Heat surfaces
  • Cooling surfaces
  • Heating systems with 3-way valves
  • Air con. system with 3-way valves
  • Chiller pumps

The calculated control mode for constant curve is a feature of the Grundfos ALPHA range, MAGNA3 and TPE3 circulator pumps.
