How to Use Water Pump: Examples, Pinouts, and Specs

The Maruf M_02 Water Pump is a versatile and efficient device designed to move water from one location to another. It is commonly used in applications such as irrigation systems, drainage solutions, water supply systems, and small-scale DIY projects. With its compact design and reliable performance, the M_02 is suitable for both hobbyists and professionals.

Below are the key technical details and pin configuration for the Maruf M_02 Water Pump:

The Maruf M_02 Water Pump has two electrical connections for operation:

1. Power Supply: Connect the V+ pin to a DC power source (6V to 12V) and the GND pin to the ground of the power source. Ensure the power supply can provide sufficient current (at least 1.2A for peak performance).
2. Water Connections: Attach hoses or pipes to the inlet and outlet ports of the pump. Ensure the connections are secure to prevent leaks.
3. Mounting: Secure the pump in a stable position to minimize vibration during operation.
4. Control: Optionally, you can control the pump using a relay module or a transistor circuit connected to a microcontroller like an Arduino UNO.

• Voltage Range: Do not exceed the specified voltage range (6V - 12V) to avoid damaging the pump.
• Dry Run Prevention: Ensure the pump is always primed with water before operation. Running the pump dry can cause overheating and damage.
• Filtration: Use a filter at the inlet to prevent debris from entering the pump and causing blockages.
• Polarity: Double-check the polarity of the power connections to avoid reverse polarity damage.
• Cooling: Operate the pump within the recommended temperature range (0°C to 50°C) to ensure optimal performance.

Below is an example of how to control the Maruf M_02 Water Pump using an Arduino UNO and a relay module:

// Example: Controlling the Maruf M_02 Water Pump with Arduino UNO
// This code turns the pump ON for 5 seconds and then OFF for 5 seconds in a loop.

const int relayPin = 7; // Pin connected to the relay module

void setup() {
  pinMode(relayPin, OUTPUT); // Set the relay pin as an output
  digitalWrite(relayPin, LOW); // Ensure the pump is OFF initially
}

void loop() {
  digitalWrite(relayPin, HIGH); // Turn the pump ON
  delay(5000); // Keep the pump ON for 5 seconds
  digitalWrite(relayPin, LOW); // Turn the pump OFF
  delay(5000); // Keep the pump OFF for 5 seconds
}

Note: Ensure the relay module is rated for the pump's voltage and current requirements.

1. Can the pump be used with liquids other than water?
   The Maruf M_02 is designed for water only. Using other liquids may damage the pump or reduce its lifespan.

2. What is the maximum distance the pump can lift water?
   The pump can lift water up to a maximum height of 3 meters.

3. Can the pump be submerged in water?
   No, the Maruf M_02 is not a submersible pump. It must be used in a dry environment.

4. How do I control the pump speed?
   The pump speed can be controlled by varying the input voltage within the specified range (6V - 12V). However, ensure the voltage does not drop below 6V to maintain proper operation.

By following this documentation, you can effectively integrate and operate the Maruf M_02 Water Pump in your projects.
