FIELD: oil and gas industry. ^ SUBSTANCE: invention refers to oil and gas industry, particularly to pump systems for circulating fluid. The system contains a pup assembly and a driver device rotating the pump assembly. The driver device is actively connected to the pump assembly via a gearing including a master gear and a slave gear. The master gear is connected to the end of the driver device shaft via a resilient coupling. The slave gear is connected to the drive shaft of the pump assembly so that it can not turn. The driver device is flange-connected to the pump assembly housing. ^ EFFECT: reduced design expenditures, reduced noise level. ^ 3 cl, 2 dwg |
