Application and design:
Pump of K type - centrifugal, horizontal, cantilevered machine provided with a gland seal of the shaft is designed to pump water (with the exception of sea water) and liquids similar with water in density, viscosity and chemical activity. The material of the main parts- grey cast iron.
|
Liquid to be pumped:
Water (except sea water)and also other liquids similar with water in density, viscosity and chemical activity at a temperature ranging from 263 up to 358 К (from minus 10 up to +85 °С), having a value of рН=6-9 and a content of solid inclusions not exceeding 1% by mass and 0,2 mm in size.

Conventional alphanumeric designation:
K 8/18 Y3.1
where K - is the cantilever pump
8 - capacity, m3/h
18 - head, m
Y3.1 - climatic version and location category.
When the pump is supplied with a specific modification of the impeller regarding its outer diameter, the following index is to be added:
"m" - increased diameter;
"a" - reduced for the operation within the middle part of the Q-H field;
"b" - reduced for the operation within the lower part of the field.
Conventional designation adopted for 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;
