Install the constant monitoring module. When using the proper equipment, you will be able to determine in time when the liquid in the stuffing box will change its state or the mechanical seal will stop working in its normal mode. Over time, the working fluid in the pump can: - evaporate; - harden; - crystallize; - can become viscous; - can form a film on ground surfaces. The difference in pressure between the injection and suction valves can show how efficiently the pump works: - what is the best efficiency point; - suction pressure will indicate if cavitation begins; -...

In order for the centrifugal pump to work as efficiently as possible, it is necessary to take into account certain conditions. To consider these conditions in more detail, let us use the figure. The figure shows a pump with two exhaust nozzles. Imagine that it has only one nozzle, located vertically, with the friction of the pipe being ignored. Taking into account the diameter of the impeller and the rotation of the shaft at specified speeds, this centrifugal pump will push the liquid up to the maximum height. This height is the maximum head at zero flow. Pressure is the...
