Function SeriesDirectflo® DF30
Directflo® DF30 – Air operated double diaphragm pumps for dosing and transferring a wide variety of fluids.
Very compact and reliable polypropylene diaphragm pumps for medium to small volume transfer (38 l/min max.), dosing, spraying and dispensing a variety of fluids.
Typical applications are transferring and dispensing windshield wash and antifreeze solutions, pure windshield wash and AdBlue®/DEF. ATEX approved pumps are available for use in potential explosive environments and with flammable fluids, like pure ethanol.
They can be used as stand-alone pumps for transfer applications or as systems pumps in small distribution systems that include hose reels.
Pumps with dual inlet are available for 1:1 ratio mixing of fluids with similar viscosities, like windshield wash or antifreeze with water. All dual inlet pumps have 2 x 3/8” BSP (F) inlet.
