The pump is mainly configured with pneumatic drive, with electric drive options available for specific installation requirements. Depending on the working environment, customers can select aluminum alloy, cast iron, stainless steel, or PP pump bodies with different diaphragm materials for chemical compatibility and service life.
The DN50 connection size provides a larger flow channel compared with smaller diaphragm pump models, allowing more efficient transfer of high-volume liquids and particle-containing materials.
With a maximum flow capacity of approximately 14.4 m³/h and the ability to pass solid particles up to 8 mm, the 2 inch diaphragm pump is suitable for applications involving:
The diaphragm pumping principle allows the pump to handle variable viscosity and complex media while reducing the risk of blockage during operation.
Many industrial fluids cannot be efficiently transferred by conventional pumps due to high viscosity, suspended particles, or unstable flow conditions.
The 2 Inch Diaphragm Pump is designed for these demanding applications. Its wide internal passage and flexible diaphragm operation make it suitable for transferring materials containing solids, sediments, and abrasive particles.
In wastewater treatment plants, the pump is commonly used for sludge transfer and chemical dosing systems. In mining operations, it can handle slurry and drainage applications. For industrial production lines, it provides reliable material movement for processes requiring strong adaptability.
The DN50 pump specification supports different installation requirements through multiple connection configurations.
Threaded connections are suitable for compact equipment and general industrial systems, while ANSI or DIN flange connections allow direct integration with larger process pipelines.
Material selection depends on the transferred medium and operating environment. Aluminum alloy and cast iron versions are commonly used for general industrial applications, stainless steel models provide improved corrosion resistance, and PP versions are available for selected chemical applications.
The diaphragm can be configured with NBR, neoprene, fluororubber, or PTFE materials according to fluid characteristics.
