Blagdon B15 PTFE Non-Metallic Pump
Blagdon B15 PTFE Non-Metallic AODD Pump
The Blagdon B15 PTFE Non-Metallic air-operated double diaphragm (AODD) pump is designed for demanding chemical-transfer applications where strong chemical resistance and non-metallic wetted construction are required.
Available in virgin PTFE and conductive PTFE configurations, the B15 provides maximum delivery up to 48 litres per minute (13 gal/min) and operating pressure up to 7 bar (102 psi). Its compact construction makes it suitable for controlled transfer of aggressive and corrosive process fluids.
The pump uses a proven pneumatic air-valve system and can handle particles up to 2 mm. Conductive PTFE X15 configurations are available for applicable ATEX hazardous-area installations.

Virgin PTFE vs Conductive PTFE
Virgin PTFE: Provides highly inert non-metallic wetted construction for a wide range of compatible aggressive chemicals and corrosive process fluids.
Conductive PTFE: Provides PTFE chemical resistance together with conductive properties required for selected hazardous-area applications. Blagdon X15 ATEX configurations apply to conductive PTFE pumps.
