A DC solenoid pump, also known as a direct current Solenoid Pump or a magnetic drive pump, is a type of pump that uses the principles of electromagnetism to move fluids. It operates based on the interaction between a magnetic field and a solenoid (a coil of wire) to create a reciprocating motion that drives fluid through the pump.
Here's a step-by-step explanation of how a DC solenoid water pump works:
- Solenoid Coil: The pump consists of a solenoid coil, typically made of copper wire, wound around a core. When an electrical current flows through the coil, it generates a magnetic field.
- Plunger or Piston: Inside the solenoid coil, there is a plunger or piston that is typically made of a ferromagnetic material, such as iron or steel. This plunger is free to move back and forth inside the coil.
- Inlet and Outlet Ports: The DC Pump has inlet and outlet ports for the fluid it is designed to move. These ports are connected to the system you want to pump the fluid through.
- Initial Position: In its initial state, the plunger is usually at one end of the coil, either fully extended or fully retracted. The position depends on the design of the pump.
- Electric Current Flow: When you apply a DC voltage to the solenoid coil, an electric current flows through it, creating a magnetic field. The direction of the magnetic field depends on the direction of the current flow.
- Magnetic Field Interaction: The magnetic field generated by the coil interacts with the ferromagnetic plunger. Like poles repel, and opposite poles attract. So, if the plunger starts in a fully retracted position and the coil's magnetic field is oriented to attract it, the plunger will move toward the coil.
- Fluid Movement: As the plunger moves, it creates a vacuum or pressure differential within the pump chamber. This pressure differential causes fluid to be drawn in through the inlet port when the plunger retracts and expelled through the outlet port when the plunger advances.
- Reciprocating Motion: The plunger continues to move back and forth in response to the changing magnetic field as long as the electrical current flows through the solenoid coil. This reciprocating motion creates a pulsatile flow of fluid through the pump, which can be used for various applications, such as dosing or transferring fluids.
- Control and Regulation: The speed and flow rate of the Mini DC Pump can be controlled by varying the voltage applied to the solenoid coil or by using other control mechanisms. This allows for precise control of the fluid flow.

Can you run a DC mini solenoid pump with AC?
In general, DC Micro Solenoid Water Pump cannot run directly on alternating current because the characteristics of direct current and alternating current are different. Direct current is a constant current, while alternating current is a constantly changing current. If it is necessary to use AC power to drive a DC electromagnetic water pump, it can be achieved through some conversion equipment.
One method is to use a rectifier to convert alternating current into direct current, and then supply it to the DC electromagnetic water pump. Rectifiers can convert alternating current into unidirectional direct current. Commonly used rectifiers include single-phase bridge rectifiers, three-phase bridge rectifiers, etc.
Another method is to use a frequency converter to convert alternating current into stable alternating current, and then convert this alternating current into direct current for use by the DC electromagnetic water pump. The frequency converter is a device that can adjust the frequency of the AC power supply to the required frequency, thereby controlling the output voltage and current of the AC power supply, and can achieve high-efficiency regulation.
It should be noted that when using AC to drive a DC 24V solenoid pump, it is necessary to select the appropriate voltage and frequency to ensure that the water pump will not be damaged. At the same time, you need to pay attention to safety issues to avoid accidents such as electric shock.

Do DC 24v vibration solenoid pumps have inrush?
DC electromagnetic pumps may generate surge current when starting. Surge current refers to the high-intensity pulse current generated at the moment when the power is turned on or when the circuit is turned on and off. Since the current of the DC electromagnetic pump will suddenly change from zero to a larger value when it is started, a surge current may occur.

How does the electromagnetic coil of a mini solenoid water pump affect the change of current?
The electromagnetic coil of the DC electromagnetic pump affects the change of current by interacting with the power supply. When the DC power supply is turned on, current passes through the electromagnetic coil to produce a magnetic field.
This magnetic field interacts with the magnetic poles of the electromagnetic pump, creating a push that moves the pump's piston or diaphragm.
The design and number of turns of a solenoid coil affects the strength and distribution of the magnetic field it produces. When the magnetic field interacts with the magnetic poles, it creates a push that moves the pump's piston or diaphragm. This moving piston or diaphragm pushes the liquid from one side of the pump to the other, thereby delivering the liquid.
In this process, the working current of the electromagnetic coil is closely related to the intensity and distribution of the magnetic field. If the design or number of turns of the solenoid is changed, it will have an impact on the change in current flow, affecting the performance and efficiency of the pump.
In addition, when the power supply is disconnected, the magnetic field gradually disappears and the driving force disappears. At this point, the pump's piston or diaphragm stops moving and liquid stops flowing. Therefore, the design and number of turns of the solenoid will also affect the pump's shutdown speed and response time.
