1. Suction pressure is less than or equal to 1.0 MPa, or pump system maximum operating pressure equal to or lower than 1.6Mpa, the pump suction inlet pressure and pump head is less than or equal to 1.6Mpa, pump hydrostatic test pressure of 2.5MPa, when ordering please specify system operating pressure. When the pump system operating pressure is greater than 1.6MPa, it shall be put forward in order to make the flow part and connection part of the pump to be used in the manufacture of cast steel.
2. Ambient temperature <40 degrees, relative humidity <95%.
3. The volume of solid particles in the transport medium is not more than 0.1% of the unit volume, particle size of <0.2mm.
Note: such as the use of medium with fine particles, please note in order to manufacturers to use wear-resistant mechanical seal.
