1. Patterns and performance line with devices of the selected pump flow, head, pressure, temperature, cavitation flow, suction process parameters such as requirement.
2. Characteristics of requirements must be met.
On the transportation of flammable, explosive and toxic or expensive media pump requires reliable shaft seal or sealless pumps, magnetic drive pumps, diaphragm pumps, canned motor pump
Pump to transport corrosive medium, requires a convection part of corrosion-resistant materials.
Pump to transport containing solid particle medium, requires a convection component with wear-resistant materials, shaft seal, if necessary rinse with clean liquid.
3. High mechanical reliability, low noise and little vibration.
4. Economically to consider equipment costs, running costs, maintenance fees and management fees are the lowest total cost.
5. Centrifugal pump with high speed, small size, light weight, high efficiency, high traffic performance, simple structure, fluid pulsation-free, smooth, easy operation and convenient maintenance and so on.
