This dataset contains the performance of 6 ESPs models operating with viscous single-phase flow. Data includes measurements of suction and discharge pressure and temperature, mass flow rate, shaft torque and rotational speed. These 6 ESPs models were tested at 1800, 2400, 3000 and 3500 rpm, 11 viscosities ranging between 1273 and 24 cP (1020 to 20 mm2/s). Standard performance curves in water service are also presented for different rotational speeds. In summary, there are 181 best efficiency points (BEPs) and more than 5800 operating conditions. Detailed descriptions of ESPs models, experimental facility, instrumentation, working fluids, test matrix and experimental procedure are presented in the related publication. Additional information on fluid properties is presented in the file "fluid properties.pdf".
