Selection of pumps and manufacturers
Thread Content
Our plant has newly installed a hydrogenation unit with an annual capacity of 1 million tons. Should a reciprocating pump be chosen for the high-pressure feed water pump? Is it better to choose a high-speed pump? (Flow rate 12.5 m³/h, head 890 m)
12.5 m3/h, head 890 m, falling within the hydraulic range of Sundyne high-speed pumps. Jialite in China, as well as the high-speed pumps produced by the 11th Aerospace Research Institute, will work as well. High-speed centrifugal pumps are more stable and reliable than reciprocating pumps. It is recommended to use high-speed centrifugal pumps.
For low flow rates but high head, I think reciprocating pumps are more suitable.
For water pumping, leakage is acceptable; therefore, a reciprocating pump is a good choice. High-speed pumps are too difficult to maintain – the slightest carelessness can lead to their failure.
I also tend to think that reciprocating pumps are more suitable: 1. The flow rate is low, and the pressure is not high either； 2. Reciprocating pumps are easy to maintain and have a low failure rate
