Constant differential pressure

Constant differential pressure can be used in circulating systems with a pipe system with low pressure loss and with control valves to generate a variable flow.

The pressure drop in the control valves is higher than 50 % of the total pressure drop.

• Heating systems with 2-way valves
• Air-con system with 2-way valves

Grundfos circulator pumps and water transfer pumps ensure constant differential pressure flow in domestic and commercial buildings and air conditioning applications.
