Questions regarding pump selection
Thread Content
There are so many different series of water pumps. How should one choose? After determining the required head and flow rate, there are several series of horizontal centrifugal pumps that meet these requirements, as well as vertical pumps that also satisfy the criteria. So how does one make a choice then? What are the differences between them? For example, the DG series, SLW series, IS series, KQL series

First, whether it should be a vertical or horizontal design depends on the requirements of the site; usually, there is no strict restriction. Horizontal pumps are easy to maintain, while vertical pumps save space. The differences between different models usually lie in their respective standards, structures, and operating conditions. Pumps that comply with API standards have higher requirements and are typically used in heavy-duty and critical applications. The requirements of ISO5199 and ASME B73.1M are slightly lower.
Thank you, but I still don’t understand. For example, between the IS series and the DG series, when the head and flow rate are the same, how should I make a choice? Should I consult the manufacturer?

If you only consider the flow rate and head, either of the two should work. As for the specific details, it’s better to ask the manufacturer for more information
Prepare a data sheet with information such as medium properties, flow rate, head, outlet pressure, net positive suction head, material, and explosion-proof requirements, and submit it to the client; they can choose the type they prefer
