Is It Possible For A Centrifugal Pump To Suddenly Fail In Delivering When In Operation Due To Gland Problem?
The centrifugal pump installed in my factory which sucks water from the tank below suddenly fails to deliver the solution .this happens when the pump is operational.Is it due to air ingress from the stuffing box?we have a conventional type asbestos gland packing .To rule out the usual possibilities i have checked the sucktion pipe and flanges for any leakage.
