1/2" Heavy Duty Air Operated Double Diaphragm Pump - QBK-15 for Diesel, Grease, Kerosene Transfer (13GPM) - Ideal for Waste Oil, Industrial Fluids & Chemical Handling

The high-quality aluminum alloy die-casting parts are integrally formed, with good sealing performance and not easy to leak. The muffler effectively reduces the noise generated when the air pump is working. Features: Air-operated double diaphragm pumps With 1/2 in. inlet and outlet 1/4 in. air inlet 3/32 in. maximum diameter suspended solids Good abrasion resistance Chemical and heat resistance Maintainability, ideal for use with water Ideal for use with low viscosity petroleum fluids. Versatile Use：The diaphragm pump with convenient operating are widely used in various industries, such as petroleum, metallurgy, mining, coating material, printing, paper making, water treatment, automotive etc. PERFECT PUMP Features an externally serviceable air distribution system and all-bolted construction. Modular air valve is stall-free, this low pulsation air valve provides smooth and rapid changeover for increased efficiency and minimizes down time. The diaphragm pump uses compressed air as a power source, for various corrosive liquids, with granular liquid, high viscosity, volatile, flammable, toxic liquid, can be exhausted and sucked out.（Not applicable to more than 70 degrees) Detail1 The structure is simple and there are few wearing parts. The pump has a simple structure and is easy to install and maintain. The connection is tight and can be used well. Detail2 Once the end of the stroke is reached, the gas distribution mechanism automatically introduces compressed air into another working chamber, pushing the diaphragm in the opposite direction, so that the two diaphragms move back and forth synchronously.

【HIGH PERFORMANCE】Our air-operated double-diaphragm pumps feature PTFE diaphragms for durability and long service life. Diaphragm pump housing is made of polypropylene material, bolted, leak-proof, sturdy, and will not fall off after long-term use.

【WORKING PRINCIPLE】A diaphragm is installed in the working chamber on both sides of the air diaphragm pump, and the central link is combined 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.

【VERSATILITY】Our diaphragm pump can handle all kinds of waste oil, alcohol, hydraulic oil, gasoline, diesel, detergent, beverage and other fluids. It is widely used in petroleum, metallurgy, mining, coatings, printing, water treatment and automotive industries.Multiple porting options for your application needs.

【OPERATING PARAMETERS】Operating temperature range -20℉ ~ 150℉; Maximum pressure 100psi; Maximum flow 2m³/h (13 GPM); Maximum lift 69 m (226.4 ft).Motor design delivers optimum air efficiency.

【ENVIRONMENTALLY SOUND】Bolted construction for leak-free fluid handling.Unbalanced air valve ensures no-stall operation
