The relevant parameters of the DC brushless water pump provide you with some detailed information.

Flow rate:

The flow rate of the DC brushless water pump depends on many factors, including impeller diameter, speed, pump room structure, etc. Generally speaking, the flow rate of common household DC brushless water pumps ranges from 50-300L/min. The size of the flow rate will affect the applicable scenarios of the system. Small flow pumps are suitable for household water supply, and large flow pumps are suitable for industrial or agricultural irrigation.

Head:

The head refers to the maximum height to which the pump can pump water. The head of the DC brushless water pump is generally between 10-60 meters. The higher the head, the greater the motor power required, and the efficiency will also decrease. Choosing the right head is very important to ensure the normal operation of the system.

NPSH:

NPSH refers to the allowable suction height of the pump under specific working conditions, which is an important parameter to prevent cavitation in the pump. The NPSH of the DC brushless water pump is usually around 1-3 meters. This parameter will change with the changes in factors such as speed and flow, and this needs to be considered when selecting.

In general, the flow rate, head and NPSH of a brushless DC water pump are interrelated and need to be reasonably selected according to the actual application scenario. If you have other specific questions, please feel free to consult me.
