1.5 Inch Diaphragm Pump

The 1.5 inch diaphragm pump is one of the most widely used sizes in chemical processing and industrial equipment systems. Compared with DN25 models, it provides higher flow output while maintaining a relatively compact structure, making it suitable for production lines where space is limited but larger transfer capacity is required.

Available in pneumatic and electric drive configurations, Xiafeng 1.5 Inch Diaphragm Pump can be manufactured with aluminum alloy, stainless steel, cast iron, PP, or PVDF pump bodies according to different media requirements. It is commonly applied in chemical material transfer, slurry handling, wastewater treatment, coating production, and electroplating circulation systems.

Balanced Flow Capacity for Industrial Applications

The DN40 connection size makes the 1.5 inch diaphragm pump a practical choice for medium-duty industrial transfer.

Compared with a 1 inch diaphragm pump, the larger flow passage allows more efficient material movement and improves handling capability for liquids containing suspended particles or higher viscosity.

With a maximum flow capacity of approximately 8.4 m³/h and particle passing capability up to 4.5 mm, this specification is suitable for applications where a compact pump cannot provide sufficient capacity, while larger models may be unnecessary.

Flexible Material Selection for Different Media

Different industrial environments require different pump materials.

For general industrial transfer, aluminum alloy and cast iron configurations provide a durable and economical solution. Stainless steel models are suitable for applications requiring improved corrosion resistance and cleaner operation. For chemical fluids, PP and PVDF versions offer non-metallic wetted paths and better compatibility with corrosive media.

The diaphragm material can also be selected according to the characteristics of the transported liquid, including nitrile rubber, neoprene, fluororubber, and PTFE options.

This flexibility allows the same 1.5 inch pump specification to be adapted for different industries and working conditions.

Designed for Easy Installation and Replacement

The 1.5 inch diaphragm pump is widely adopted because of its convenient installation and compatibility with common industrial piping systems.

Standard configurations are available with threaded connections, while flange connections can be customized for equipment integration and larger process systems.

For users upgrading existing pumping systems, the DN40 specification provides a practical replacement option without requiring major changes to the overall pipeline layout.

Technical Specifications

Industrial Applications

The 1.5 Inch Diaphragm Pump is commonly selected for medium-flow transfer systems across various industries.

In chemical manufacturing, it is used for transferring raw materials, additives, and process liquids. Its ability to handle certain solid particles also makes it suitable for slurry and wastewater-related applications.

In coating and painting production lines, the pump provides stable material supply for paints, resins, and similar fluids. For electroplating systems, suitable material configurations can be selected for chemical liquid circulation and transfer.

The compact DN40 structure also makes it suitable for environmental protection equipment and small-to-medium industrial processing systems.

Pneumatic and Electric Options

The 1.5 inch diaphragm pump can be configured with different drive methods according to operating requirements.

Pneumatic models are commonly selected for chemical plants, hazardous areas, and applications requiring self-priming or dry-running capability. Since the pump operates through compressed air, it provides flexible installation without direct dependence on electrical power.

Electric versions are suitable for fixed production systems where continuous operation and stable power supply are preferred.
