FLOJET G573225A Air Operated Diaphragm Pump

FLOJET G573225A Air Operated Diaphragm Pump

FLOJET G573225A Air Operated Diaphragm Pump – Viton, 3/4" Hose Barb Ports, 5 GPM

The G573225A is designed for applications requiring a compact, pneumatic fluid-transfer pump with good chemical resistance. Its Viton diaphragm and seals make this particular configuration suitable for a range of oils, solvents and other compatible fluids.

The pump uses a patented shuttle-valve design intended to provide stall-free operation, while its compact construction and integral mounting arrangement simplify equipment installation. It can operate using either compressed air or CO₂.

Materials of Construction

Pump Housing

Polypropylene

The polypropylene housing provides a lightweight and corrosion-resistant construction suitable for many commercial and industrial fluid-handling applications.

Diaphragm

Viton / FKM

The Viton diaphragm is one of the defining characteristics of the G573225A configuration and provides compatibility with a range of oils, solvents and hydrocarbon-based fluids.

Springs

Hastelloy C

The pump uses Hastelloy C springs, providing enhanced corrosion resistance within the intended operating environment.

Performance

Maximum Flow

18.9 LPM / 5 GPM

Maximum Pressure

6.9 bar / 100 PSI

Air Supply

20–100 PSI / 1.4–6.9 bar

Self-Priming

Up to approximately 4.5 m / 15 ft

Actual flow depends on air pressure, fluid viscosity, suction lift, tubing size, discharge pressure and other system conditions.

Connection Details

Fluid Connections

3/4" Straight Hose Barb

The G573225A is specifically configured with 3/4" hose-barb fluid inlet and outlet ports.

Air Connection

1/4" Hose Barb

The air inlet is a 1/4" hose-barb connection.

Main Applications:

The FLOJET G573225A can be used in suitable systems for:

• Industrial fluid transfer
• Oil transfer
• Lubricant dispensing
• Hydraulic fluid transfer
• Power steering and transmission fluid handling
• Chemical fluid transfer
• Solvent handling
• Industrial equipment
• Pneumatic pumping systems
• Process-fluid transfer
• Commercial equipment
• Fluid dispensing systems

The Viton configuration is listed for compatibility with acids, oils, solvents, D-Limonene, aromatic hydrocarbons and halogenated hydrocarbons, among other compatible fluids.

Viton Compatibility – Important Note

The G573225A should not be treated as universally compatible with every chemical simply because it uses Viton/FKM.

The referenced material data lists ketones, acetones, automotive brake fluid, ammonia, ethanol and EGME solvent among fluids that are not allowed for this FKM configuration. Always verify compatibility based on the exact fluid, concentration and operating temperature before installation.

Main Advantages:

1. Air-Operated Design

The pump does not require an electric motor and can operate from compressed air or CO₂.

2. Compact Construction

The G57 Series provides high pumping performance relative to its compact size.

3. Stall-Resistant Operation

The patented shuttle-valve design is intended to prevent stalling during operation.

4. Chemical Resistance

The combination of polypropylene housing and Viton/FKM wetted components provides compatibility with numerous industrial fluids.

5. Dry-Run Capability

The pump is designed to tolerate dry-running conditions, although avoiding unnecessary prolonged dry operation is still recommended.

6. Easy Installation

The hose-barb configuration provides straightforward connection to appropriately sized flexible tubing.
