Diaphragm pumps are generally divided into electric diaphragm pumps and pneumatic diaphragm pumps. The primary distinctions between the two types of pumps can be found in their structure, drive mode, flow parameters, and operating principle. Next, we thoroughly comprehend the primary distinctions between them.
1. Difference in working principle
The electric diaphragm pump uses a cycloid money wheel reducer drive and a crankshaft slider mechanism to drive the double diaphragm for reciprocating incompetence. This allows the working chamber's volume to change alternately, ensuring the liquid is continuously inhaled and expelled. At the same time, breakthroughs have been made in diaphragm materials, so their service life will be greatly extended. As a result, it is increasingly being employed as replacement equipment in centrifugal pumps and screw pumps used in metallurgy, ceramics, petrochemicals, and other industries. The pneumatic diaphragm pump is powered by compressed air, which operates similarly to a plunger pump through the diaphragm's reciprocating deformation brought on by the displacement pump's volume change.
2. Differences in flow parameters
The pneumatic diaphragm pump has a head range of 0–70m, an outlet pressure range of 0–7KG, and a flow range of 0~30m³/h. Electric diaphragm pumps have a flow range of 0–20 m³/h, a head range of 0–30 m, and an outlet pressure range of 0–3 kg.
3. Variation in adaptability
A pneumatic diaphragm pump may change the flow rate by altering the gas source's pressure, but a standard electric diaphragm pump cannot change the flow rate; it requires a frequency converter to do so.
4. Explosion-proof types difference
The pneumatic diaphragm pumps are explosion-proof and can be used in a variety of flammable and explosive environments, whereas electric diaphragm pumps require an explosion-proof motor in order to fulfill the same standards.
5. Variation in the outlet's capacity to withstand pressure
While the electric diaphragm pump's outlet cannot withstand pressure (a safety valve or pressure release valve must be installed), the pneumatic diaphragm pump's outlet can.
The above is about the difference between electric diaphragm pumps and pneumatic diaphragm pumps, if you don't know if you choose between the two, you can put your requirements to inform our staff, we can recommend the right diaphragm pump for you.
