Aluminum diaphragm pump castings reduce the overall weight of portable pumps by 50%. These diaphragm pump castings are typically made from A356 alloy with T6 heat treatment. The corrosion resistance of aluminum diaphragm pump castings is enhanced with an anodized coating.
Diaphragm pump castings in aluminum are ideal for marine and mobile applications. The thermal conductivity of aluminum diaphragm pump castings helps dissipate heat from the pumped fluid. Aluminum diaphragm pump castings are often used in oil spill response equipment.
The casting process for aluminum diaphragm pump castings uses permanent molds for better consistency. Diaphragm pump castings with a hard coat anodizing (70 µm) resist abrasion. The low specific gravity of aluminum diaphragm pump castings (2.7 g/cm³) eases handling.
Diaphragm pump castings for firefighting pumps are made of aluminum for portability. The pressure rating of aluminum diaphragm pump castings is 150 psi maximum. Diaphragm pump castings with a Teflon impregnation provide non‑stick properties for sticky fluids.
The surface of aluminum diaphragm pump castings can be powder coated for chemical resistance. Diaphragm pump castings with a chromate conversion coating prevent galvanic corrosion. The impact strength of aluminum diaphragm pump castings exceeds 10 ft‑lbs.
Diaphragm pump castings for military pumps are often sand cast aluminum. The repair weldability of aluminum diaphragm pump castings is acceptable with proper preheat. Diaphragm pump castings with a flanged inlet are common for portable trash pumps.
Lightweight aluminum diaphragm pump castings enable one‑person carry of industrial pumps.
