Graco's Hydra-Clean Series

Graco makes it easy for industrial and commercial business owners to clean and maintain expensive assets in a breeze with its Hydra-Clean pressure washer series. This range comprises powerful washers that are easy to use and mobile but tough on moulds, loose paint, mud, dirt, dust, and grime from objects and surfaces. And being powered by air, these pressure washers are proven efficient and long-lasting, giving businesses a cost-effective way to maintain their facilities and equipment.

Graco Air operated double diaphragm (AODD) pumps use compressed air as a power source. The compressed air is shifted from one chamber and then to the other side by a linked shaft. This movement allows the chambers to move simultaneously. This back-and-forth motion forces liquid out of one chamber and into the discharge piping while the other chamber is being filled with liquid at the same time. These pumps use reciprocating elastomeric diaphragms and check valves to pump fluid. The liquid chambers are filled and emptied by fluid that is drawn through a common inlet and discharged through a single outlet.
