The working conditions of the vertical pump and its description are as follows: Working conditions: 1The high workpiece pressure of the system shall not exceed 16mpa。The inhalation pressure generally does not exceed 03MPa to protect the mechanical seal from not exceeding 1 of what it bears4 mpa。2.The medium is only clean water, and the volume of solid insoluble matter in it shall not exceed 01% and the granularity must not exceed 02mm。3.The ambient temperature shall not exceed 40, the altitude shall not exceed 100m, and the relative humidity shall not exceed 95%. 4.If the medium used contains fine particles, please specify it when ordering, so that the manufacturer can use wear-resistant mechanical seals. 
Note: **Zui's high working pressure shall not exceed 16MPa, which means that the system is designed to withstand stress. The inhalation pressure generally does not exceed 03 MPa, this is because the ordinary mechanical seal has a high withstand pressure of 14 mpa。If the inhalation pressure is greater than 03MPa, and the selected head is 80 meters, then the system pressure will exceed 14 MPa, which may cause damage to the mechanical seal. * The medium is only clean water, and the water quality should meet the relevant standards. If other media are used, you should communicate with the manufacturer and confirm whether the sealing material can withstand it. * The altitude must not exceed 100m, which refers to the altitude of the place where the pump is used. Above this altitude may affect the performance and life of the pump. * The relative humidity should not exceed 95%, this is to ensure the normal operation of the pump and avoid rust and other problems caused by excessive humidity.
When selecting and using a vertical pump, it is important to pay attention to the above working conditions and instructions. If in doubt, consult a professional or manufacturer.
