The lower the pumping head of the fire pump, the smaller the motor load. Under the misleading of this kind of misunderstanding, when purchasing a water pump, the head of the water pump is often selected to be very high. In fact, for centrifugal water pumps, when the pump model is determined, the power consumption is proportional to the actual flow of the pump. The flow rate of the water pump will decrease with the increase of the head, so the higher the head, the smaller the flow rate and the smaller the power consumption. Conversely, the lower the lift, the greater the flow and the greater the power consumption. Therefore, in order to prevent the motor from overloading, it is generally required that the actual pumping head of the pump should not be lower than 60% of the calibrated head.

Mechanical seals are commonly used on fire pumps to ensure reliable and long-lasting operation. These seals are designed to create a tight, reliable seal between the pump shafts, and the fire pump’s motor. Mechanical seals are typically composed of stationary and rotating components that move against each other with minimal friction, to form a mechanical seal that can withstand the stresses of the fire pump’s operation. In addition to preventing leaks, mechanical seals can help improve pump efficiency, reduce wear and tear on motor components, and increase the life of the fire pump.

Safety Valve plays a safety protection role in the system. When the system pressure exceeds the prescribed value, the safety valve opens, and a part of the gas/fluid in the system is discharged into the atmosphere/pipeline, so that the system pressure does not exceed the allowable value, so as to ensure that the system does not cause accidents due to excessive pressure.
Pressure Tank: Water is a non-compressible medium. Generally speaking, the pressure drop of fire-fighting pipe network is normal. However, the pressure drop is very slow, the total loss of water in the pipe network isnot large, and the frequent change of pressure in the pipe network leads to frequent start-up and shutdown of pumps. Especially when the power of equipment is high, it will cause great impact on pressure sensors, relaysand motors, thus affecting the performance and life whole equipment. Therefore, it is necessary to choose the right volume of the pressure tank.
