The Flojet Pulley Pump Model 03121X34B is a robust, belt-driven diaphragm pump engineered for reliable fluid transfer in demanding industrial, agricultural, and commercial applications. Designed with Flojet’s proven triplex diaphragm technology, this pump delivers consistent flow performance, long service life, and excellent resistance to wear—even in continuous-duty environments.

Key Features

• Heavy-Duty Pulley Drive System. The pulley-driven configuration allows flexible integration with external motors or engines, making it ideal for custom setups and mobile equipment. It ensures smooth, efficient operation at varying speeds.

• Triplex Diaphragm Design Provides balanced flow, reduced pulsation, and superior durability. This design minimizes vibration and extends pump life while maintaining steady output.

• Self-Priming Capability Enables fast and reliable priming without the need for manual intervention, improving usability in remote or hard-to-access installations.

• Dry-Running Protection The pump can safely run dry without sustaining damage, enhancing operational safety and reducing maintenance concerns.

• Corrosion-Resistant Construction Built with high-quality materials compatible with a wide range of fluids—including water, light chemicals, herbicides, and fertilizers—making it suitable for agricultural spraying and chemical transfer.

• Low Maintenance Operation Modular construction and durable internal components simplify servicing and reduce downtime, resulting in lower total cost of ownership.
