it is the max vertical height upto which pump can supply the water.
When a pump is pumping water from a level that is below the pump it is called suction head. If the water to be pumped is at a level above the pump, it is positive head. The pump maybe pumping from the base of a tank to a higher level such as an elevated tank or it may be pulling water from a tank that is below the pump. The distance from the center of the pump to the top of the water level would be the foot of head. It takes 2.31 feet to make 1 P.S.I. So if it is 10 feet from the center line of the pump to the water level, you would have about 4.33 P.S.I. of head.
pump eff. = (pump dynamic head x pump flow)/(pump h.p x 3960)flow=gallon per minute
1、 single stage pump refers to only one impeller pump, highest head is only 125 meters; 2、 the multistage pump means to have two or more impeller pump, highest head can more than 125 meters; Multistage pumps in single stage pump head must match two levels motor cases, by adding more impeller number to equip with level 4 motor, which can improve pump using life and reduces the noise, but multistage pumps maintenance is relatively more difficult than single stage pump. 3、 pump actual required head is less than 125 m, can according to pump room area, pump prices (multistage pump price usually higher than single stage pump) factors comprehensive consideration to choose single stage pump or multistage pumps. With the development of technology, single stage impeller pump through improving the speed of the pump to improve pump head, can replace multistage pumps, just the price is more expensive.
The circ pump is used to circulate the water thru the filter. The booster pump is for running the pool sweeper.
Head 30mts Discharge 120 cu.mt water pump
it is the max vertical height upto which pump can supply the water.
The 6m head pump can lift 6 meters. The 5m head pump can lift 5m. Note this has no impact on the volume of liquid that is pumped.
The fuel pump is located inside the fuel tank on a Range Rover. You will have to remove the whole fuel tank to get to the fuel pump.

Booster pump has various price range. But generally it will cost you approximatley the price range between $1543.23 or $1311.75
there is no reason to pull the head to get at the oil pump.
Pump head unit; is either in Feets fluid- us unit or in meters fluid- metric units
Negative Suction Head means the pump is drawing liquid up from below its centerline. The distance between the centerline of the pump and the surface of the fluid is measured in head feet, this can be negative (below the pump) or positive (above the pump).
The fuel pump is located inside the fuel tank on a 1988 Range Rover 4.6. The fuel pump usually needs replaced after 100,000 or more.
Hilton Head Range Rear Light was created in 1880.
