SAMOA Directflo®
DF 30 and DF 50 – compact double diaphragm pumps for general industrial applications. For dosing, transferring and extracting oils, fuels and aqueous media.
GRACO AODD Pumps
Versatile double diaphragm pumps for water, antifreeze, oil and AdBlue – with high free passage also for solids-laden media. Also available with dual inlet for special applications.
PRO ONE – EX Version
ATEX-certified double diaphragm pumps for diesel, kerosene and oil – PRO ONE 15 with 50 l/min and PRO ONE 25 with 160 l/min. For use in Ex zones and with flammable liquids.
PIUSI & MATO Oil Pumps
PIUSI MA130/MA140 and MATO DP-60 specifically for high-viscosity oils and waste oil – diaphragm pumps reliably handle viscous media that would overload gear or centrifugal pumps.
Which double diaphragm pump suits which application?
Chemicals & Acids
Double diaphragm pumps are the first choice for aggressive media – acids, bases, solvents. Material selection is crucial: PP, PVDF or stainless steel, seals in PTFE or EPDM.
Waste Oil & High Viscosity
The PIUSI MA130/MA140 are specifically designed for waste oil and high-viscosity oils. Diaphragm pumps handle viscous media that would overload gear or centrifugal pumps.
ATEX & Ex Zones
The PRO ONE EX versions are ATEX-certified for diesel, kerosene and flammable liquids in Ex zones. No electric motor – no spark risk, intrinsically safe.
AdBlue & Water
The GRACO double diaphragm pump for AdBlue is made from food-grade materials – for urea solution 32.5%, water, antifreeze and other aqueous media.
High Throughput
For large transfer volumes: the PRO ONE 25 with 160 l/min or the GRACO with dual inlet for continuous operation in industrial filling and transfer systems.
No Power Available
All double diaphragm pumps operate purely on compressed air – ideal for outdoor areas, mobile use or locations without mains power. A compressed air network of 4–7 bar is sufficient.
