Principles for selecting sewage pumps - DFIN Pump Industry

1. High mechanical reliability, low noise, and minimal vibration.

2. Economically, it is necessary to comprehensively consider the total cost of equipment, operation, maintenance, and management fees to minimize them.

3. Make the selected pump type and performance meet the requirements of process parameters such as device flow rate, head, pressure, temperature, cavitation flow rate, and suction stroke.

4. Must meet the requirements of medium characteristics.

For pumps that transport flammable, explosive, toxic, or valuable media, reliable shaft seals or leak free pumps are required, such as magnetic drive pumps, diaphragm pumps, and shielded pumps

For pumps transporting corrosive media, it is required that the convection components use corrosion-resistant materials, such as AFB stainless steel corrosion-resistant pumps and CQF engineering plastic magnetic drive pumps.

For pumps transporting media containing solid particles, it is required that the convection components be made of wear-resistant materials, and if necessary, the shaft seal should be flushed with clean liquid.
