Conversion From Constant Flow System To Variable Flow

Apr 29, 2010 · Converting the system to variable flow alone while retaining constant speed pumps will save pumping energy; typically 20% to 30%. This energy saving does not come easily however. As the flow from constant speed pumps is throttled by 2-way valves the pressure across the pumps and the control valves increases. This leads to some

Injection Versus 4-Way Valves - PM Engineer

Sep 30, 2002 · For optimum performance, a variable speed injection system must be flow balanced so the injection pump operates at or close to full speed under design load conditions. This balancing is not necessary with a 4-way mixing valve. The use of variable speed injection mixing has been steadily increasing in North America in recent years.

Upgrading ESBE 4-way mixing valve Question (Glenn H
