As a mancufacuter, we received many inquiries about centrifugal pump, but also we found that many customers don't know what are the specification means about the pump they need.
Firstly, what is head? HEAD is the Height of a column of water that can be supported by the pressure or vacuum exerted at the pump.
Head pressure describes how powerful a pump is. Although many manufacturers provide a head-capacity performance curve for their pumps, it can be difficult to predict the exact point on the curve where the pump will perform. Typically, “total static head” is considered when selecting a pump. However, this method can be unreliable due to frictional losses. In many cases the pump performance will not meet expectations.Static suction head is the vertical distance between the pump impeller to the surface of the liquid on the suction side of the pump. Static discharge head is the vertical distance between the pump's discharge port and the highest point of the discharge hose, which is the liquid surface if the hose is submerged or pumping into the bottom of a tank.
