Aluminum Alloy Diaphragm Pump Casting: Lightweight Housing for Portable Pump Systems

The aluminum alloy diaphragm pump casting is gravity die-cast from A356 or ADC12 alloy, offering a weight reduction of approximately 40 percent compared to cast iron equivalents while maintaining pressure ratings up to 8 bar.

Field service teams and agricultural spray operators prefer the aluminum alloy diaphragm pump casting because the lighter pump assembly reduces mounting strain on trailers and enables one-person handling during maintenance.

For pump assemblers, a reliable aluminum alloy diaphragm pump casting provides T6 heat treatment for improved dimensional stability and machined mounting bosses for motor and bracket attachments. A well-designed aluminum alloy diaphragm pump casting also incorporates ribbed wall sections to reduce vibration-induced fatigue in high-cycle diaphragm operation.
