Application and design: Pump of 2K type - centrifugal, horizontal, cantilevered machine furnished with a stuffing box seal of the shaft is designed to pump water (except sea water) and liquids similar with water in density, viscosity and chemical activity. The shaft is provided by a stuffing box seal having "fluid" lubricant treatment of the bearing subassemblies. The material of the basic components - grey cast iron.

Liquid to be pumped: Service water (except sea water), and also other liquids similar with water in density, viscosity, chemical activity having a temperature ranging from 263 up to 378K (from minus 10 up to +105°C) and with pH=6:9 and a content of solid inclusions not exceeding 1% by mass and 0,2 mm in size.

Conventional designation:

2K80-50-200 Y3.1 TY 3631-096-05747979-97
where 2K-cantilever pump with "fluid" lubricant treatment of the bearing subassemblies;
80 - diameter of inlet branch, mm;
50 - diameter of outlet branch, mm;
200 - diameter of impeller (conventional), mm;
Y3.1 - climatic version and location category.
When the pump is supplied with a specific modification of the impeller according to its outer diameter, the following index is to be added:
"m" - increased diameter;
"a", "b" - reduced diameter.

Conventional alphanumeric designation of the characteristic curves:
Q - capacity, m³/h;
H - head, m;
N - maximum power consumption, kW;
n - frequency of rotation, rpm;
 - efficiency, %;
- admissible positive suction head;;
