Nigerian customers ordered the following two sets of water pumps
1. Raw water submersible pump
-Q = (120-130) Cubic meter/hour
-H = (150-160) M
-Efficiency = 80%
2. High lift pump
– 130 Cubic meter/Hr
– 100 M
– P = 75 %
After communicating with customers, we suggest submersible sewage pumps. They are multistage centrifugal pumps, and the pump head will be high. The impeller channel is large to prevent impellers obstruction, so it works well during the raining season.
