Pumps oil NPV type

NPV — pumps centrifugal vertical one-stage with driving wheels of a bilateral entrance, with the preincluded wheels with axial supplies and dvukhzavitkovy spiral branches.

The pumped-over environment: creations of a cavitational stock, necessary for their work, are intended for supply of oil with a temperature from -5 °C to +80 °C, with kinematic viscosity of 1-3x10-4 ^cm3 / with, ^{with a density of 830-900 kg/m3}, the content of mechanical impurity up to 0,06% on volume and particles up to 0,5 mm in size to oil main pumps also.

Scope: for supply of oil to oil main pumps.

Units are installed on the open areas with a temperature of air from-50 to +40 °C.

Symbol: NPV 1250-60-1 (2,3), where
NPV — the pump or the unit oil retaining vertical;
1250 — giving in the nominal mode, ^m3/h, without undercutting of the driving wheel;
60 — a pressure in the nominal mode, m, without undercutting of the driving wheel;
1(2,3 …) — a pump design;
1 — the main option of execution;
2 — the shortened option of execution of the pump with the reduced size of deepening of the worker
wheels (without intermediate sections) — for the pumping-over stations having static a subtime for beskavitatsionny operation of the pump;
3 — the option of execution of the pump with a demountable shaft can be not to base of the basic (1/3) or the shortened execution (2/3), allowing to make replacement of face consolidation,
the intermediate bearing without dismantle of the electric motor;
