Centrifugal pumps type CNP

centrifugal pumps designed to work as part of pumping units for oil production and water injection into the reservoir (hereinafter - pumps). The pumped liquid is a mixture of oil, associated water, mineral impurities and oil gas and has the following characteristics:
1) maximum density, kg/m31400;
2) hydrogen index of associated fluid pH
for basic design5,0 - 8,5;
for corrosion-resistant modification3,0-9,0;
Short-term (up to 6 hours) decrease of pH to 0 is allowed.
3) maximum kinematic viscosity of single-phase liquid, at which the pump operation is provided without changing the head and efficiency, 1 mm2/sec
