Air-Operated Double Diaphragm Pump QBK-25L, 1” Inlet & Outlet, 24 GPM, 29-115 PSI for Industrial Use

Introducing the QBK-25L Air-Operated Double Diaphragm Pump, a robust and efficient solution for a wide range of industrial applications. This powerful pump is designed to deliver high performance with a maximum flow rate of 24 gallons per minute (GPM) and operates effectively under pressures ranging from 29 to 115 PSI. Its 1-inch inlet and outlet make it ideal for various fluid transfer needs.

The air-operated double diaphragm pump utilizes the reciprocating action of durable diaphragms made from rubber, thermoplastic, or Teflon. This mechanism not only ensures efficient fluid transfer but also provides excellent abrasion and heat resistance, contributing to the pump’s long service life. The design of the motor optimizes air efficiency, making it a cost-effective choice for your industrial needs.

With a maximum fluid temperature of 80°F and the ability to handle suspended solids up to 1/8 inch in diameter, this diaphragm pump is versatile enough for various fluids including low viscosity petroleum products like diesel and motor oil. However, it is important to note that the pump is not suitable for corrosive liquids such as acids or alkalis.

The working principle of the QBK-25L is based on two symmetrical working chambers, each equipped with a diaphragm. Compressed air enters through the pump inlet and is directed into one of the chambers, causing the diaphragm to move and pump fluid. As the diaphragm reaches the end of its stroke, the air distribution mechanism seamlessly switches to the opposite chamber, allowing continuous fluid pumping. This synchronized motion ensures efficient operation and reliability.

This diaphragm pump is compact and lightweight, making it easy to install and operate in various industrial settings. It is widely used in industries such as petroleum, metallurgy, coatings, mining, printing, paper making, water treatment, and automotive applications. The solid construction of the QBK-25L guarantees durability and performance, providing peace of mind for users across various sectors.
