Description
Units Electroly pumping stamps x160-29D-r (subsequently units) are designed to pump chemically active and neutral liquids with a density of not more than 1500 kg/m³, kinematic viscosity up to 30*10-6 m²/s, having solid inclusions of not more than 0.2 mm , the volumetric concentration of which is not more than 0.1 % with the temperature of the pumped liquid from 0 to +70 ° C.
Pumps included in the unit are produced in the climatic performance of UHL, placement category 4 GOST15150-69, are made:
-According to the material of the flowing part P (coating of the running part-rubber 51-1632 TU38-1051082-86);
- By the type of seal of the pump shaft:
- With a double omplex seal- sd ;
- With a single end seal- 3a . .
Units of general industrial performance do not allow the installation and operation of them in explosive and fire hazardous industries and should not be used to pump combustible and easily igniting liquids, as well as for pumping dielectric fluids with a specific resistance of 105 Ohms and higher.
The conditional designation of the unit in order, correspondence and other documentation is adopted in accordance with GOST10168.0-85 with the designation of climatic execution and the category of accommodation according to GOST15150-69.
For example: x160/29d-rd-SHL4 ST PC00218035-001-201 1, where:
x -designation of the pump type;
160 -feed in m3/h;
29 -pressure in m;
D -increased diameter of the working wheel;
P -the symbol of the material of the prototypery part of the pump;
SD -Double saline seal;
UHL -climatic execution;
4 -category of operation during operation.
