Proper material selection in liquid pump lines

  • PRODUCT

The pump tubing in a delivery system can have a significant impact on the performance of the pump. When connecting a liquid diaphragm pump to a system, engineers face numerous material choices for both the suction and discharge pump lines. Selecting the appropriate material is often more complex than it may initially seem. Therefore, it is extremely important to understand the most significant positive and negative impacts that the pump piping materials can have, as well as to know how to avoid or leverage those impacts.
