This post was last edited by HP0377 on 2018-7-6 07:08. Basic Process Knowledge (Multiple Choice) 20180706: What will not cause a decrease in the suction pressure of the boiler feed pump? A. Severe blockage of the hot water and filter layers B. The suction valve is not fully open C. Increased pump speed D. The discharge valve is not fully open Hint: Even in case of impeller-type feed pumps, failing to fully open the discharge valve only results in a decrease in flow rate and a reduction in the flow resistance in the suction pipe, while the other factors lead to an increase in the suction flow resistance.
