Air-Operated Double Diaphragm Pump 1′ Inlet & Outlet, 24 GPM, 115 PSI, for Diesel & Oil Transfer

Introducing the powerful Air-Operated Double Diaphragm Pump, model QBK-25L, specifically engineered for industrial use. This pump features a robust design with a 1-inch inlet and outlet, allowing for high flow rates of up to 24 gallons per minute (GPM) and operates efficiently within a pressure range of 29 to 115 PSI. The diaphragm pump is particularly well-suited for transferring low viscosity fluids such as diesel, kerosene, and motor oil, making it an essential tool for various industries including petroleum, metallurgy, mining, and automotive.

One of the standout features of this diaphragm pump is its unique motor design that optimizes air efficiency, ensuring consistent operation without stalling. The pump utilizes a combination of reciprocating action from a rubber, thermoplastic, or Teflon diaphragm, paired with suitable valves to manage fluid movement effectively. This design not only enhances pumping efficiency but also provides excellent abrasion, chemical, and heat resistance.

The diaphragm pump operates on a positive displacement mechanism. It consists of two symmetrical working chambers, each equipped with a diaphragm. When compressed air enters the valve, it directs air into one of the chambers, promoting diaphragm movement in that chamber while the opposite chamber releases gas. This alternating action continues, facilitating a smooth pumping process.

Ideal for applications that require reliability and efficiency, this air-operated diaphragm pump is perfect for use in various industrial sectors. It is particularly effective for transferring water and low viscosity petroleum fluids, making it a versatile addition to your equipment. However, please note that this pump is not suitable for corrosive liquids.

Included in the package is the Air-Operated Double Diaphragm Pump and a comprehensive product manual to guide you through installation and operation. Invest in the QBK-25L diaphragm pump for a reliable and efficient pumping solution that meets the demands of your industrial applications.
