Cantilever pumps, KM

Cantilever pumps, KM
Units of type K, KM are used to supply water for drinking and industrial-commercial purposes with the content of mechanical impurities not more than 0.1% by volume and particle size of not more than 0.2 mm, with temperatures ranging from 0 to 85 °C, as well as other liquids similar to water in density, viscosity and chemical activity.
Pumped liquid:

Water (except sea), as well as other liquids similar to water in density, viscosity and chemical activity, with temperatures ranging from 263 to 358 K (from -10 to +85 °C), pH=6-9, containing solid inclusions is not more than 1 mass% and not more than 0,2 mm

where-To - console
8 - flow, m3/h
18 - head, m
U3.1 - climatic version and location category.
When the supply pump with one of the variants of the impeller outer diameter, is added to the index:
"m" is increased in diameter;
"a" is reduced to work in the middle of the field Q-N;
"b" is reduced for operation in the lower part of the field.

Conventions on the graphical characteristics:
Q - flow, m3/h;
H - head, m,
N is the maximum power consumption, kW;
n - rotational speed, Rev/min;
- Efficiency, %;
- allowed positive suction head;
