Use CasesSafe transfer of sodium hydroxide over a long distance and with high-pump-head piping
Customer's Needs and Problems
We want to transfer sodium hydroxide over a long distance and with high-pump-head piping (total lift: 85 m) and inject it into the main pipe.
- This is a dangerous liquid, so pumps that have a risk of liquid leakage cannot be used.
- Air chambers cannot be used with high-pump-head piping (the air dissolves into the transfer liquid), so pumps with pulsation cannot be used.
We suggested that the customer use a Smoothflow Pump, which uses a diaphragm method and has no pulsation, and they agreed to this proposal.
- The pump has a sealed structure without shaft seals, so there is no need to be concerned about liquid leakage.
- Because the liquid can be transferred with a continuous, constant flow and no pulsation, there is no need for an air chamber.
- Because there is no pulsation, the pressure loss inside the pipe is small, making it possible to transfer the liquid over a long distance and with high-pump-head piping without having to apply an excessive amount of pressure.
