When securing a distillate pump on a low pressure fresh water evaporator, which of the listed steps should be carried out FIRST?

🔍 Key Concepts

• Normal shutdown sequence for a centrifugal pump (what is usually done before changing valve positions) • Purpose of the three-way solenoid dump valve on a distillate line in an evaporator system • Effect of sealing line valves and pressure gage valves when the pump is still running

💭 Think About

• Think about which action immediately removes the source of flow and pressure in the system before you touch any valves or instruments. • Ask yourself: which of these steps, if done first, makes all the other steps safer and reduces the chance of damage or leaks? • Which listed step would normally be considered a "follow‑up" or protective step, rather than the primary shutdown action for the pump itself?

✅ Before You Answer

• Verify the typical order for securing a centrifugal pump: what comes first—stopping the driver or changing valve positions? • Consider what the three-way solenoid dump valve actually does in operation (high salinity or contamination protection) and whether that is a normal first shutdown step. • Check whether closing sealing line valves or pressure gage valves while the pump is still operating could risk damage to mechanical seals or loss of monitoring.
