Pump pressure head is proportional to pressure. Pressure corresponds to head, 1 MPa pressure is equal to about 100 m Yang head. micro small flow pump head is the energy obtained through the unit weight of the liquid through the pump, which includes potential energy, pressure energy and velocity energy and other parts, so the outlet pressure is only part of it. The relationship between the power of the pump and the flow and head is: Power = 9.81 * flow * head * efficiency, efficiency = 0.85 or so.

1. "Pressure" and "head" parameters belong to the pressure unit of micro small flow pump, and belong to the same physical quantity. Pump head = suction head + pressure head It should be noted that the head indicated on the nameplate is the head that the pump itself can produce, and it does not include the loss of head caused by the frictional resistance of the water flow in the pipe.

2. The parameters "pressure" and "height" are interchangeable and can therefore sometimes be expressed in the same pressure units. For example, the most common unit of "head" is "meter", and "pressure" can also be expressed by how many meters.

3. "Head" refers to the new "maximum vertical head", the new "maximum vertical height" of how high the water can be played from the drain; "maximum Pressure" refers to the maximum impact force that can be shown by the pump output under the maximum load.

4. "Head" is usually measured in "meters" of equal height, usually with a measuring tool such as a tape measure; "maximum pressure" is usually measured in megapascals (MPA) or kilograms. units. Usually expressed as pressure.

5. Different types of applicable micro small flow pumps

6. "Maximum pressure" is usually used in areas such as miniature self-priming pumps and micro pumps. The general "head" is usually used for submersible pumps, such as micro submersible pumps and micro DC vacuum pumps.
