Ideal for use with low viscosity petroleum fluids including diesel, kerosene, motor oil and some waste oil. This powerful and efficient air operated diaphragm pump is perfect for all your needs in every industry!Working PrincipleIn the pump two symmetrical working chamber each equipped with a diaphragm, the center link will be integrated into one. Compressed air from the pump inlet into the valve, through the valve body to introduce compressed air into one of the chamber to promote movement of the diaphragm chamber, while the other chamber gas emissions. Once the end of the stroke is reached, the gas distribution mechanism automatically introduces compressed air into the other working chamber to push the diaphragm in the opposite direction so that the two diaphragms move back and forth in unison.FeatureAir-operated double diaphragm pumpWith 1/2 inch inlet and outlet1/4 Inch air inletWith 0.32 inch gas nozzleGood abrasion resistance and heat resistanceServiceability and environmentally soundPerfect for use with waterIdeal for use with low viscosity petroleum fluidsWidely used in various industriesPackage Content1 x Air-Operated Double Diaphragm Pump QBK-151 x Product Manual

• 【Diaphragm pumps】Pneumatic diaphragm pumps are maintainable and provide easy access to the spherical check valve and liquid cap for maintenance and repair. Material: Cast iron, with good wear resistance and heat resistance; Type: double diaphragm; Operation mode: pneumatic;
• 【Integration】A diaphragm is installed in each of the two symmetrical working chambers of the pump, and the central connecting rod integrates it into a whole, bolt structure, and tight leak-free fluid handling.
• 【Excellent performance】This product is about 12gpm 1/2 inch inlet and outlet pneumatic double diaphragm pump. This powerful pneumatic double diaphragm pump QBY4-25L features a 1/4 inch air intake. The motor design provides optimal air efficiency.
• 【Automatic compressed air】The double diaphragm pump features an externally repairable air distribution system and a fully bolted construction. Stall-free, this low-pulsation air valve provides smooth and fast transitions, increasing efficiency and minimizing downtime.
• 【Purpose】This pneumatic double diaphragm pump is suitable for water and low adhesion oil. Do not use corrosive liquids!
