Metallic Diaphragm Pumps
Metallic diaphragm pumps are made with pump bodies in materials such as stainless steel, aluminum alloy, or cast iron, giving them the strength needed for heavier industrial fluid transfer. They move liquid through the reciprocating action of the diaphragms, which draw fluid into the chambers and discharge it in a controlled flow. Compared with plastic diaphragm pumps, pumps made of metal are widely used for applications involving higher mechanical stress, higher-temperature media, viscous liquids, slurries, or fluids containing particles. Both air-operated and electric models are available, so they can be chosen according to the available power source and working environment.
- Metallic pump bodies provide higher strength and better wear resistance, which supports longer service life in demanding working environments.
- Metallic diaphragm pumps can operate in higher-temperature conditions and are suitable for transferring hot media when the pump material, diaphragm, and seals are correctly selected.
- These pumps can handle different types of fluids, including corrosive liquids, high-viscosity materials, and media containing particles.
-
Stainless Steel Diaphragm PumpsStainless steel diaphragm pumps are used in processes that need stronger pump bodies and cleaner contact with the liquid.
-
Aluminum Diaphragm PumpsAluminum diaphragm pumps use a lightweight aluminum alloy body and diaphragm-based fluid transfer to handle neutral or mildly corrosive liquids in general industrial applications.
-
Stainless Steel Containment Duty Diaphragm PumpsStainless steel containment duty diaphragm pumps are air-operated diaphragm pumps with an added leak detection system for diaphragm failure.
-
Aluminum Containment Duty Diaphragm PumpsAluminum containment duty diaphragm pumps are air-operated and include a diaphragm failure alarm system.
-
Stainless Steel Sanitary Air Operated Diaphragm PumpsStainless steel sanitary air operated diaphragm pumps are positive displacement pumps used in hygiene-sensitive processing applications, such as food, beverage, pharmaceutical, and cosmetic manufacturing.
-
Stainless Steel Air Operated Powder PumpsStainless steel air operated powder pumps are made for transferring light dry powders through a closed pipeline.
Metallic diaphragm pumps are commonly used in industries that handle tough fluids, heavier process conditions, or media containing particles:
- Chemical Processing: Corrosive liquids, high-viscosity fluids, and chemical media that may contain suspended particles
- Oil and Petroleum: Oil well drainage, oil transfer, oily wastewater, and other petroleum-related fluids.
- Food and Pharmaceutical Production: Food ingredients, slurries, juices, liquid medicines, process solutions, and similar fluids.
- Wastewater Treatment: Sewage treatment, sludge transfer, wastewater recovery, and other treatment-related applications.
- Mining and Metallurgy: Slurry transfer, tailings treatment, and fluid handling in metal smelting or mineral processing
