Tips: Difference between air diaphragm pump and electric diaphragm pump
- The air diaphragm pump is driven by compressed air (2-8.4 kg air pressure), and the electric diaphragm pump is driven by an electric motor.
- The maximum flow rate of the pneumatic diaphragm pump is 60m/h, and the flow rate of the electric diaphragm pump is only 28m/h.
- The pneumatic diaphragm pump can adjust the flow rate by adjusting the pressure of the air source. The electric diaphragm pump cannot adjust the flow rate. The adjustment can only be achieved with a frequency converter.
- The air diaphragm pump is structurally explosion-proof and is suitable for all kinds of flammable and explosive places, while the electric diaphragm pump must use an explosion-proof motor to meet the explosion-proof requirements.
- The pneumatic diaphragm pump is cheaper and lighter.
