Introduction
The QBK-50 air operated diaphragm pump is designed to handle a wide range of liquids, including corrosive and abrasive materials. It is ideal for use in the chemical industry due to its durable construction and efficient operation. The pump features a 50mm inlet and outlet size, making it suitable for various applications. Its stainless steel construction ensures resistance to corrosion and long-lasting performance.
Features
1. Self-priming capability without any rotating parts, allowing dry and wet priming with a self-priming height of up to 8 meters.
2. A sectional design enables the pump to convey two different liquids simultaneously using a double diaphragm system.
3. Can be used as a submersible pump, powered by air instead of electricity, reducing safety risks like leakage and electrical hazards.
4. Provides stall-free and ice-free operation, ensuring reliable performance in various conditions.
5. Bolt joint design offers even sealing pressure for optimal efficiency and durability.
6. High-quality imported materials are used for the diaphragm, ball, and ball seat, extending service life.
7. Suitable for use in potentially explosive environments due to its pneumatic motor.
8. Capable of pumping corrosive, volatile, flammable, toxic fluids, as well as those containing particles and high viscosity.

About Us
Welcome to visit our factory!
An air cooler turbine is a device used in an air cooler that increases air flow and improves air cooling efficiency. A turbine is a rotating piece made up of a series of blades that turn as air passes through the turbine, creating a powerful flow of air. This airflow takes heat out of the air, making it cooler. The air cooler turbine is usually driven by a motor and can be adjusted as needed for speed and air volume. It is widely used in automobile, robot, electronic equipment and other fields.
Air cooler, referred to as "air cooler", also called fin fan, commonly used to replace the water cooled shell - tube Heat Exchanger cooling medium. It is a device for cooling or condensing the high temperature process fluid inside the tube by sweeping the finned tube with ambient air as the cooling medium. Air cooler is mainly used in petroleum, chemical, metallurgy and other air cooler supporting use, with large air volume, high efficiency, low vibration, low noise, easy maintenance and other advantages.
The main business scope is various heaters, waste heat boilers, pressure vessels, supportingair preheaters, air coolers, furnace accessories and accessories, and provide equipment installation, with EPC ability of projects. At present, our customers have covered all large and medium-sized petrochemical enterprises in China and established long-term strategic cooperative partnership with them. Products are exported to Southeast Asia, Middle East, and other regions.
