documents: #Person1#: How often do you service the pump?
  #Person2#: We take very good care of this particular pump. It's a crucial part of our process. We clean it and flush it through at the end of every shift, We check the high pressure seals, recalibrate the gauges and lubricate all moving parts weekly. We replace the gaskets every month.
  #Person1#: How do you decide how often these things need to be done?
  #Person2#: Well, from experience we can predict the lifespan of different components. We try to replace components before they fail or wear out. This prevents the equipment from breaking down. It also saves us a lot of trouble!
