How to Choose a Slurry Pump According to the Working Requirements of the Whole System

Proper sizing is one of the key factors to improve the service life of the pump.

The appropriate pump performance parameters are selected according to the working requirements of the whole system.

Speed: For conveying high-concentration strong abrasive slurry, the highest speed of the pump (the highest number of revolutions of multiple revolutions in the performance curve) is generally not selected, and it is more appropriate to choose about 3/4 of the revolution. When the selected pump is suitable for flow and the head is not reached, multiple pumps can be used in series.

Flow rate: The flow range of different slurries should also be limited; For slurry with high concentration and strong abrasion, the flow rate should be within the range of 40-80% of the flow rate corresponding to the maximum efficiency of the pump; For abrasive slurries with low concentration, the flow rate should be selected within the range of 40%-100% of the corresponding flow rate of the maximum efficiency of the pump. Generally, it is not selected in the range of 100%-120% of the flow rate corresponding to the maximum efficiency.

Head: During the operation of the slurry pump, the performance of the pump decreases continuously due to the wear of the overflow parts, until it finally cannot meet the requirements of the working conditions. In order to keep the pump running for a long time around the rated operating conditions, a head margin is usually added when selecting the pump. The general margin is 10% of the rated head.
