Sectional centrifugal pumps (hereinafter referred to as the pump) type 180 are designed for pumping water with a temperature of up to 45 ° C, with the content of solid mechanical impurities of not more than 0.1 % in weight, with the size of solid particles of not more than 0.1 mm, microcharles not more than 1, 47 GPA. The maximum permissible pressure at the entrance to the pump is not more than 0.25 MPa (2.5 kgf/cm2).
The pump should be made in the climatic design of the UHL, the placement category 4 GOST 15150-69.
The pumping center of 180-85 has a designation:
Central nervous system - centrifugal section of sectional;
180 - nominal feed in m3/h;
85 - pressure in m.
Characterization of the Pump POPS 180
The working part of the characteristics at a rotation frequency of 1475 rpm is located in the feed interval 135 ... 225 m3/h.
The main parameters of the pump corresponding to the nominal mode of operation on water with a temperature of 20 ° C and a density of 998.2 kgf/m3
