2018年9月17日 · 1. Before talking about a pump, consider the pipe. Velocity of liquid in pipes ranges between 3 to 10 feet per second (ft/sec). If the velocity is too slow, the dirt, sludge or other contaminants can settle. If flow is too fast, abrasive wear will reduce the life of the pipe.
All water pumps are composed of two basic selections: Electric motor and hydraulic section. The support is utilized to secure the pump to the base and prevent it from moving. TO CHOOSE A PUMP WE NEED TO KNOW 2 BASIC VALUES: FLOWRATE AND LIFT PRESSURE OR HEIGHT (OR HEAD)
