Diaphragm Pump Component

- DC Motor: Gives the pump mechanism the power it needs to operate.
- Diaphragm: A flexible membrane moves, compressing air in the pump cavity.
- Pump Cavity: The chamber where the diaphragm moves, compressing the fluid or air.
- Inlet/Outlet Valves: Manage the liquid or air flow entering and leaving the pump.
- Pump Housing: Encases and protects the diaphragm and other internal components.
- Compression Spring (if applicable): Ensures proper diaphragm movement and air compression.
- Seals: Prevent leaks and ensure airtight operation within the pump chamber.
- Mounting Bracket: Holds the pump assembly securely in place within the appliance.
By Structure
We offer customizable single-chamber and dual-chamber air diaphragm pumps, tailored for your home appliance needs, ensuring optimal performance.
Single-chamber Air Type
- Only one diaphragm and pump chamber.
- Less smooth operation, as it pumps in one direction per stroke.
- Suitable for low flow or moderate-pressure applications, such as in small appliances.
Two-chamber Air Type
- Two air diaphragm pumps work alternately for air compression and displacement.
- Offers better fluid transfer and less pulsation.
- Used in dishwashers, washing machines, and large vacuum cleaners requiring higher flow.
By Material
We provide customizable plastic and metal diaphragm pumps, offering durable, reliable solutions for home appliances based on your requirements.

Plastic
- Plastic diaphragm pumps are perfect for low-pressure applications in household appliances because they are affordable, lightweight, and resistant to corrosion.
- They are commonly used in coffee machines, dishwashers, and water pumps.
Metal
- Metal diaphragm pumps are perfect for high-pressure applications because of their increased strength and longevity.
- Used in demanding appliances requiring robust fluid transfer, like vacuums cleaners.
