Wilden 3″ air-operated double diaphragm pump — T15 metal
The Wilden T15 is a 3-inch metal AODD pump from the Pro-Flo range. Its clamped-band body makes assembly and maintenance simple, and it complies with ATEX for use in hazardous areas. It is built for high-flow general industry work: oil and gas, dewatering, paints and coatings, ceramics and mining.
Why sites choose AODD pumps
- Air-driven — no electric motor at the pump, so no sparks; suited to flammable or explosive atmospheres.
- Self-priming and can run dry without damage, and can be stopped by closing the discharge.
- Handles difficult fluids — abrasive slurries, viscous products, solids and corrosive chemicals, depending on the materials chosen.
- Simple maintenance — diaphragms, balls and seats are the wear parts.
What to send for a quote
- The fluid, its temperature, and whether it carries solids or is abrasive or corrosive.
- Flow rate and discharge pressure or head you need.
- The model code if you are replacing a pump (this one is T15/AAAAB/BNS/BN/BN), or the body, diaphragm and ball materials.
- Spare parts you want with it: diaphragm kits, balls, seats.
