Overview
The Balcrank 1120-039 CenterFlo CF65 is a high-capacity air-operated double diaphragm pump engineered for demanding fluid transfer operations in automotive, fleet, and industrial environments. Featuring Buna-N diaphragms and check balls, this aluminum-bodied pump delivers up to 65 gal/min through 1-1/2 inch NPT ports while operating across a 22-102 psi air pressure range. The CenterFlo reversed flow design provides superior back-pressure performance, exceptional dry suction lift, and reduced air consumption compared to conventional AODD pumps. Ideal for transferring anti-freeze, light oils, windshield wash solution, and used fluids, the CF65 serves car and truck dealers, fleets, mining operations, lube trucks, and in-plant transfer applications with dependable, maintenance-free operation.

Key Features
CenterFlo Reversed Design
Proprietary flow-through architecture positions air motor centrally for superior back-pressure resistance, minimal flow loss, and exceptional suction lift performance that eliminates self-priming concerns when pumping from drums or tall tanks.
Lube-Free Pivot Air Valve
Dependable directional pivot air valve requires no lubrication, tolerates oil, moisture, and dirt contamination, prevents icing, and eliminates air leaks when pump is stalled against system head pressure for reliable starts every time.
Energy-Efficient Operation
Reduced air consumption per gallon pumped compared to traditional AODD designs saves energy costs and eliminates the need for larger compressor capacity, delivering measurable operational savings over the pump lifecycle.
Buna-N Wetted Components
Buna-N diaphragms and check balls provide excellent chemical resistance for anti-freeze, light oils, and common automotive fluids while aluminum, acetal, and stainless steel wetted parts ensure long-term durability.
Field Serviceable Design
Modular air motor and fluid sections allow external servicing after installation without removing the pump from service position, minimizing maintenance downtime and simplifying component replacement procedures.
Solids Handling Capability
1/4 inch solids handling capacity accommodates suspended particles in used oil, contaminated anti-freeze, and real-world automotive fluids, reducing clogging concerns and extending service intervals in demanding transfer operations.
