Description
Units Electroly pumping stamps x65-50-160 rub (subsequently units) are designed to pump chemically active and neutral fluids with a density of not more than 1850 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);
-according to the type of seal of the pump shaft-with a double omplex seal- sd .
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: x65-50-160r-SD-UHL4 ST PC00218035-001-2011 , where:
x -chemical horizontal, console on a separate rack;
65 -input diameter in mm;
50 -exit diameter in mm;
160 -the nominal diameter of the working wheel in mm;
P -the symbol of the material of the prototypery part of the pump;
SD -Double saline seal;
UHL -climatic execution;
4 -the category of placement during operation
