1 Inch Diaphragm Pump

The pump is available in pneumatic and electric drive configurations, with material options including aluminum alloy, stainless steel, PP, and PVDF. This allows customers to select suitable combinations according to the characteristics of the transferred medium, such as chemical liquids, coatings, wastewater, or process fluids.

Xiafeng supplies 1 Inch Diaphragm Pump solutions for equipment manufacturers, industrial distributors, and end users requiring reliable performance in compact pumping systems.

Compact Size with Industrial Performance

The DN25 (1 inch) connection size makes this diaphragm pump a popular choice for applications where installation space is limited but stable flow output is still required.

Compared with larger diaphragm pump models, the 1 inch version requires less piping space and offers lower installation costs. At the same time, it maintains the advantages of diaphragm pumping technology, including self-priming capability, dry-running tolerance, and the ability to handle liquids containing small solid particles.

For workshops and processing systems requiring flexible material transfer, the 1 inch diaphragm pump provides a convenient and economical solution.

Multiple Configurations for Different Applications

The performance of a diaphragm pump largely depends on material selection and drive configuration.

For general industrial applications, aluminum alloy models provide a lightweight and cost-effective option. Stainless steel versions are suitable for applications requiring better corrosion resistance and durability. PP and PVDF models are commonly selected for chemical transfer where non-metallic wetted materials are preferred.

The pump can also be equipped with different diaphragm materials, including nitrile rubber, neoprene, fluororubber, and PTFE, allowing customers to match the pump with different liquid properties and operating environments.

Suitable for Replacement and Equipment Integration

The 1 inch diaphragm pump size is widely used because of its compatibility with common industrial piping systems.

Many users select this specification when replacing existing pumps or integrating pumps into compact equipment. Standard threaded connections, including NPT and BSPT options, simplify installation and reduce modification requirements.

For OEM equipment manufacturers, Xiafeng can provide customized configurations according to flow requirements, connection standards, and application conditions.
