How does a change in the viscosity of the fluid being transported affect the performance of a centrifugal pump? Answer: As the viscosity of the fluid being transported increases, the energy losses inside the pump increase as well. As a result, both the flow rate and head of the pump decrease, efficiency drops, but the shaft power increases. http://down.hcbbs.cc/attachment/forum/201706/10/203353z7y06fdo70r6eod0.jpg Petrochemical Zone—New Ideas for Energy Savings: The “Creative Thinking” Campaign (The second phase of this campaign is in full swing) http://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1666758 (Source: Haichuan Chemical Industry Forum)

As the liquid viscosity increases, the Reynolds number decreases, hydraulic friction losses increase, which results in a decrease in head and flow rate; thus, the Q-H curve declines (although the head at the shut-off point remains almost unchanged). At the same time, the shaft power increases due to the increased friction losses, causing the pump’s efficiency to drop sharply; meanwhile, the allowable net positive suction head also increases.
