Pumps are one of the key elements used in different industries, including oil and gas, petrochemicals and water treatment. Their range of applications is very wide and process requirements mandate the use of specific types and designs. Due to that wide range, it sometimes becomes challenging to select the right pump design that fits some applications. One such application is the low-flow, high-head (LFHH) pump, which requires the use of low specific speed designs, which are commonly known by their sensitivity to operate within a wide operating range due to the narrow operating window from their best efficiency point (BEP). This makes the reliability of low specific speed pumps questionable.
