Is it necessary to turn the automatic fire pumps and foam pumps over manually on a regular basis?

I would like to ask the experts here whether it is necessary to manually rotate these pumps? If needed, how should it be structured?
Regular turning of the shaft is required; it should be turned at least 180 degrees
Yes, it is not possible to carry out shaft rotation before temporary startup; therefore, it is necessary to perform regular shaft rotation checks to assess the condition of the pump. This includes checking the valves and oil level on a monthly basis, as well as carrying out several shaft rotation tests per month – just as with regular inspections of fire protection systems
Also pay attention to the direction of turning the crank – turn it in the direction of operation! Don’t operate the control panel carelessly; it’s more likely to cause problems that way
It is necessary; it’s best to add a set of inspection systems.
Regular turning and starting. Turning the steering wheel with the motor can be harmful to the mechanical seal when done in the reverse direction. The horizontal pump disc rotates 180 degrees to prevent shaft flexure. Just add a few more turns to the vertical pump disc. Failing to clean it for a long time can also cause the grease to stick together and solidify.
Regular turning of the shaft is necessary; it is recommended to carry out periodic trial runs (for example, once a month or once a quarter). Switch to manual mode when turning the crank to avoid accidents.
