Diaphragm DC 7.4V Oxygen injection micro air pump

What is the difference between air operated and Electric Diaphragm Pump?

1. Power Source:
- Air Operated Mini Diaphragm Pump: These pumps are powered by compressed air. They typically have an air inlet and outlet, which are connected to an air compressor. The compressed air creates the necessary pressure to move the diaphragm and pump the fluid.
- Electric Diaphragm Pump: Mini Air Pump is powered by electricity. They are connected to an electrical power source, such as an outlet or a battery. The electric motor drives the diaphragm and generates the pumping action.
2. Operation:
- Air Operated Diaphragm Pump: These pumps use compressed air to move the diaphragm back and forth, creating suction and discharge strokes. The air pressure alternately fills and empties the chambers on either side of the diaphragm, causing the fluid to be drawn in and pumped out.
- Electric Diaphragm Pump: These pumps use an electric motor to drive the diaphragm. The motor rotates an eccentric cam or other mechanism, which pushes and pulls the diaphragm to create the pumping action.
3. Control and Adjustability:
- Air Operated Diaphragm Pump: These pumps offer more precise control and adjustability. The air pressure can be adjusted to regulate the flow rate and pressure of the pumped fluid.
- Electric Diaphragm Pump: This Electric Air Pump also provides control and adjustability, but it is typically done through the motor speed control. By adjusting the motor speed, the flow rate and pressure can be modified.
