Description
Electric pumps of the AHVMS20/31 brand (further electric pumps) are designed to pump chemically active and neutral liquids with a density of not more than 1650 kg/m³, kinematic viscosity up to 30*10-6 m²/s, having solid inclusions of not more than 1.0 mm, voluminous concentration which is not more than 1.5 % with the temperature of the pumped liquid from minus 40 to +90 ° C, including: soda solution in washing machines and perchloreline solvents (C2SL4) and trichloretille of technical (C2NSL3), contaminated during cleaning of clothing and workwear. < /p>
Electric pumps are produced in climatic design of U, placement category 2, 3 GOST15150-69, and are made:
-According to the material of the flowing part K, K1 ;
-By the type of seal of the pump shaft-a single end seal 2 (like 211 ).
Electric pumps of general-industrial execution 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.
The symbol of the electric pump during 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: AhVMS20/31-K-2-U2 joint venture PK00218035-001-2011 , where:
- Ah -designation of the pump type;
- in -vertical;
- M -monoblock;
- C -self-digging;
- 20 -feed in m3/h;
- 31 -pressure in m;
- K -the symbol of the material of the flow of the pump;
- 2 -type of shaft seal (single end-211); ); );
- U -climatic execution;
- 2 -category of accommodation during operation.
When supplying electric pumps with wiped working wheels providing operation on the middle and lower curve of the Q-H field, the letter " A ”or“ b ", respectively.
