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.

TACMINA's Solutions

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.
