Function SeriesDirectflo® DF50

Directflo® DF50 – Air operated double diaphragm pumps for dosing and transferring a wide variety of fluids.

Very compact and reliable diaphragm pumps for medium volume transfer (50 l/min max.), dosing, spraying and dispensing a variety of fluids.
POLYPROPYLENE PUMPS have a polypropylene air motor. Typical applications for these pumps are transferring and dispensing of 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 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.
