Piusi AODD Oil Transfer Pump – Air-Operated Double Diaphragm Pump for High-Viscosity Oils
The Piusi AODD Air Operated Diaphragm Oil Transfer Pump is an innovative addition to the Piusi pump range — the first air-operated double diaphragm (AODD) pump in their product offering. Engineered for the transfer of high-viscosity lubricating oils, including waste engine oils containing suspended solid contaminants, this pump is designed for severe-duty conditions in commercial workshops, industrial plants, and any environment where hazardous area classification requires compliant equipment.
ATEX Zone 2 Certified for Hazardous Workshop Environments
The AODD design uses a NBR (nitrile) diaphragm to transfer fluid via positive displacement, which means it is self-priming, can be run dry without damage, and can handle suspended solids up to 4mm in size — making it genuinely suitable for transferring contaminated waste oil and sludge without risk of blockage. The pump achieves a maximum head of 70m at 7 bar air supply, providing the pressure needed to transfer viscous fluids over meaningful distances. Its ATEX Zone 2 certification means it is safe for use in workshop and industrial environments where flammable vapours may occasionally be present. Models are available in port sizes from 1/2" to 1.5" G, with flow rates from 50ltr/min to 220ltr/min for larger installations.

Applications and Usage
The Piusi AODD Oil Pump is the go-to choice for waste engine oil collection and transfer in commercial garages, vehicle recycling yards, and industrial oil management operations. It is equally effective for transferring clean high-viscosity lubricants from drums or IBCs where the oil's thickness makes conventional vane pumps inappropriate. The ATEX Zone 2 rating makes it safe for installation in enclosed workshop areas where engine run-down vapours may be present. The pump's ability to run dry eliminates the risk of pump damage when containers are nearly empty — a common operational challenge with non-diaphragm pump types in this application.
