Reliable AODD Pumps for Battery Manufacturing

Wilden Battery Manufacturing

• Are AODD pumps safe for flammable solvents in battery manufacturing?

  Yes. Air-operated double-diaphragm (AODD) pumps have no electric motor to act as an ignition source. Wilden aluminum and stainless steel Pro-Flo SHIFT Pumps are fully conductive and groundable, which allows them to be ATEX-rated for use in explosive environments. For aggressive flammable chemicals, Wilden also offers Alloy C, conductive polypropylene and conductive PVDF pumps.

• Can AODD pumps handle highly abrasive battery materials without premature wear?

  Yes. AODD pumps have no mechanical seals and can be fitted with diaphragms and check balls made from abrasion-resistant thermoplastic elastomers such as Wil-Flex™, Saniflex™ and Bunalast™. These materials resist abrasion better than standard rubber. Chem-Fuse Integral Piston Diaphragms (IPDs) extend diaphragm life further by eliminating outer piston abrasion.

• Can AODD pumps handle high-viscosity battery slurries?

  Yes. AODD pumps can handle high-viscosity battery slurries with viscosities up to 25,185 cPs. 
  To get the most out of your pump in high-viscosity applications:

  • Use large suction lines, up to three times the size of the pump ports to minimize friction losses
  • Position the pump as close to (or below) the level of the fluid as possible
  • Start the fluid slowly using an air line valve and set the air pressure and crack the valve open slowly

  High viscosity also affects pump performance, so consult the viscosity correction guide when reading performance curves.

• Why choose AODD pumps over other positive displacement pumps for lithium-ion cell manufacturing?

  AODD pumps offer greater containment, safety and flexibility than many other positive displacement technologies. They have no mechanical seals, and bolted configurations provide the highest level of product containment. Chem-Fuse IPDs remove the leak path between the diaphragm and outer piston. An optional leak-detection system on the pump exhaust adds protection if a diaphragm ruptures. AODD pumps are also available in a wide range of materials to suit the chemistries used in lithium-ion cell manufacturing.
