How should a general centrifugal pump be kept in standby? (Short answer) Answer: 1. The inlet valve is fully open. 2. The cooling water flow is unobstructed. 3. The lubricating oil is normal. 4. Check valve bypass is open. 5. If the pump starts automatically and the outlet valve is open, set to “AUTO”. 6. Rotate the machine regularly.

1. Open the inlet valve fully; if freezing is possible, drain the liquid inside the pump and refill it before starting the pump, or slightly open the filter next to the check valve to maintain flow. 2. If available, keep the cooling water unobstructed. 3. The lubricating oil is in good condition, with the oil level at 1/2 to 2/3. 5. If the pump starts automatically and the outlet valve is open, set to “AUTO”. 6. Perform regular turning of the pump to check its condition.
