Air Operated Double Diaphragm Pump 35 GPM Cast Iron 120 PSI for Low Viscosity Petroleum Fluids

The Air Operated Double Diaphragm Pump is a robust and efficient solution designed for a variety of fluid transfer applications. This high-performance pump, model Qby4-25l, is engineered to handle low viscosity petroleum fluids, making it perfect for tasks involving diesel, kerosene, motor oil, and certain waste oils. With its impressive capability to pump up to 35 gallons per minute (GPM) and operate under a maximum pressure of 120 PSI, it stands out in its category.

The working principle of the air-operated diaphragm pump is quite fascinating. It consists of two symmetrical working chambers, each equipped with a diaphragm. A central connecting rod integrates these diaphragms, allowing for synchronized movement. When compressed air enters through the pump inlet, it fills one of the chambers, causing the diaphragm to move and pump fluid. As this happens, the other chamber is exhausted, creating a continuous flow of fluid. This mechanism ensures that the pump operates efficiently, even under varying conditions.

Ideal for applications involving water and petroleum fluids, this diaphragm pump features a sturdy construction that guarantees durability and reliability. The dual diaphragm design minimizes the risk of leaks and enhances the pump’s overall efficiency. Additionally, it is designed to handle suspended solids up to 3 mm (1/8 inch) in diameter, making it versatile for various pumping tasks.

With a self-priming capability of up to 3 meters (10 feet) and a maximum suction lift of 5 meters (16.4 feet), this pump can operate effectively in diverse environments. The double diaphragm system also allows for dry operation up to a certain extent, providing flexibility in its use.

In summary, the Air Operated Double Diaphragm Pump is a powerful and reliable choice for anyone needing to transfer low viscosity fluids efficiently. Its combination of high flow rate, durable materials, and innovative design makes it an essential tool for both professional and industrial applications.

Included in the package is the air-operated double diaphragm pump along with a product brochure that provides further details on its features and benefits.
