Pumps oil centrifugal vertical booster pumps type NPV 300-60 and electric pumping units on their basis, are designed to supply oil to mainline pumps, as well as for pumping light petroleum products, with temperature from minus 15 0C to plus 60 0C, density from 700 to 900 kg/m3, kinematic viscosity from 0,5-10-6 to 300-10-6 m2/s, maximum size of solid particles - 4 mm and maximum mass fraction of mechanical impurities - 0,05%.
Pump type NPV - centrifugal, vertical, two-casing, sectional type with apparatuses guided or spiral outlet, with impeller of I stage of single-entry single-entry with pre-coupled wheel.
The principle of operation of the pump is to convert the mechanical energy of the drive from an external source (motor) to the hydraulic energy of the liquid flow.
The electric pump unit consists of a pump and a motor connected to each other by means of a coupling, elastic bush-finger or plate coupling. The pump is made with a support...
