The Aluminum Body Reduces Weight

Aluminum is lighter than cast iron

Cast iron pumps are heavy. An aluminum alloy pneumatic diaphragm pump manufacturer uses aluminum alloy bodies that weigh significantly less. The pump is easier to carry and position.

The aluminum body resists corrosion in many applications

Aluminum forms a protective oxide layer. An aluminum alloy pneumatic diaphragm pump manufacturer uses aluminum that resists water, mild chemicals, and many industrial fluids.

The lighter weight reduces installation cost

Lightweight pumps need less support. An aluminum alloy pneumatic diaphragm pump manufacturer produces pumps that can be mounted on lighter brackets and structures.

Common specs for aluminum alloy pneumatic diaphragm pumps:

  • Flow rate: 5L/min to 400L/min
  • Pressure: up to 8 bar
  • Body material: aluminum alloy
  • Diaphragm materials: NBR, EPDM, PTFE
  • Connections: threaded
  • Weight: lighter than cast iron
  • Drive: pneumatic
