Sept 11, 2020, the two submersible sewage pump is installed and testing, running well. Customer inquiry: 30 cubic meters per hour, 150 meters head, vertical install and submerged in clean water, local site is in mine. Because it is clean water, deep well submersible pump is also available for customer’s local site, and smaller motor power. However, the Indonesia customer still stick to bottom suction submersible sewage pump. When we choose one water pump model, we need to take pipeline loss into seriously. Maybe it will have small flow.
If a submersible water pump is lower flow, the reason as below:
1. higher head in actual
2. motor reversal
3. pipeline seal water leakage
