Key Features

Patented CenterFlo Technology

Reversed air/fluid design with fluid path through center and air motor outside provides improved suction performance, less air consumption, and reduced pulsation throughout the performance curve

Superior Suction Capability

Exceptional 13.2 ft dry suction head and 26.25 ft wet suction head eliminate self-priming issues when pumping from drums, tall tanks, or below-grade storage

Dependable Lube-Free Air Valve

Directional pivot air valve starts every time and is tolerant of oil, moisture and dirt with non-icing operation and no air leaks when stalled against system pressure

Energy Efficient Design

Reduced air consumption per gallon pumped saves compressor energy and avoids the need to upgrade to larger air compressor capacity

In-Line Serviceability

Air valve, diaphragms, and ball valves can be serviced without disconnecting pump from fluid distribution line, minimizing downtime and simplifying maintenance

Minimal Pressure Loss

Superior performance against back pressure with nominal loss of flow and pressure capacity under real-world application conditions for consistent fluid delivery

Ideal Applications

Quick lube facilities and automotive dealerships for DEF, anti-freeze, transmission fluid, and windshield wash dispensing
Tire shops and service centers for fluid transfer and distribution up to 10 gal/min flow rate
Industrial plants and manufacturing facilities for in-plant lubricant and fluid transfer applications
Mobile lube operations and fleet maintenance for portable fluid dispensing systems

Frequently Asked

What fluids can the Balcrank 1120-034A CenterFlo CF10 pump handle?+
The 1120-034A is designed to handle diesel exhaust fluid (DEF), anti-freeze (glycol), automatic transmission fluid, motor oil, windshield washer solution, and waste oil. The polypropylene construction and chemical-resistant wetted materials (PTFE, Viton, Hytrel, stainless steel) make it suitable for a wide range of automotive and industrial fluids. Maximum particle size in suspension is 0.12 inches (3 mm).
What air pressure is required to operate this pump?+
The CenterFlo CF10 operates on an air pressure range of 43.51 to 100 psi (3 to 7 bar). The air inlet connection is 3/8" NPSM female. At 100 psi air supply, the pump delivers 10.4 gpm with a 1:1 pressure ratio, meaning fluid output pressure equals air input pressure. The energy-efficient design reduces air consumption per gallon pumped compared to conventional diaphragm pumps.
How does the CenterFlo design differ from conventional AODD pumps?+
The patented CenterFlo design reverses the traditional AODD configuration by routing fluid through the center of the pump with the air motor positioned on the outside. This innovative layout provides significant advantages including superior dry suction lift (13.2 ft), improved performance against back pressure, reduced pulsation for better metering accuracy, lower air consumption, and the ability to service components in-line without disconnecting from fluid lines.
