First, understand pump selection principles
1, make the selected pump type and performance accords with equipment capacity and head, pressure, temperature, flow rate, suction cavitation parameters requirements.
2, must satisfy the medium characteristic request.
To transport inflammable, explosive toxic or precious liquids of pump shaft sealing dependable, request or use without leakage pump, such as magnetic drive pumps, diaphragm pumps, shielding pump
For the pump forhandling corrosive medium, demanding convection parts adoption corrosive materials, such as AFB stainless steel corrosion pumps, CQF engineering plastic magnetic drive pumps.
For conveying solid particles medium pumps, request convection parts adoption wear-resistant materials, when necessary, shaft seal with adopts clean liquid washing.
3, machinery in high reliability, low noise, vibration
