Safety in Pumps design
(OP)
I would like to know what are the safety aspects to be built in a rotary equipment while finalising a vendor offer.

RE: Safety in Pumps design
Seriously, what kind of safety are you talking about, pump operational safety, such as including various shut-down switches, or PP as in coupling guards, etc.?

1. Thermal sensing devices can be installed to measure the temperature of the liquid in the pump volute. A lower warning temperature and an automatic pump shut down temperature can be programmed in this type of controller.
2. Motor current sensing devices can be installed in the system which alert and automatically shut down the pump whenever the motor amps drop below the expected operating range for any critical period of time. Pump motor amperage drops when the pump ceases to pump material, indicating a system problem.
3.Flow sensing devices can be installed which automatically shut down the pump if flow stops for any critical period of time. These devices can be simple paddle switches in a clean fluid such as well water or they may be more sophisticated devices which do not come in contact with the fluid such as magnetic flow meters for aggressive fluids such as slurries.
4. Vibration sensors and shutdown switches can be installed at critical locations on the pump.
