Plunger pump issue, urgent.
Thread Content
It seems there is a rule stating that, to prevent danger, the plunger pump should not be stopped while under pressure. So, isn’t it true that it’s also difficult to drive when the back pressure is too high?
That’s not the case; once you understand the working principle of the plunger pump, you’ll see that it has little to do with back pressure
The motor is protected; high back pressure can affect operation.
A plunger pump is designed for high backpressure transmission; as long as the backpressure does not exceed the pressure at the pump’s outlet, if it does, there is an issue with the pump’s selection
Could you explain in detail what the relationship is between motor protection and the difficulty in starting under backpressure?
