Introduction
The QBK-50 air operated diaphragm pump is a high-performance device designed to handle corrosive and hazardous liquids. Powered by compressed air, this pump features a 50mm inlet and outlet size, making it ideal for industrial applications. The pump is constructed with stainless steel, ensuring durability and resistance to corrosion. It is widely used in the chemical industry for transferring various types of liquids, including those that are abrasive, viscous, or contain particles.
Features
1. Self-priming capability without any rotating parts, allowing both dry and wet priming with a self-priming height of up to 8 meters. 2. Modular design enables dual-diaphragm operation, suitable for handling two different liquids simultaneously. 3. Can be used directly as a submersible pump, eliminating leakage risks and reducing maintenance costs compared to motor-driven pumps. 4. Designed for stall-free and ice-free operation, ensuring consistent performance under various conditions. 5. Bolt joint structure ensures even sealing pressure for optimal efficiency and reliability. 6. High-quality imported materials for diaphragms, balls, and ball seats extend service life. 7. Ideal for use in potentially explosive environments due to its pneumatic power source. 8. Capable of pumping corrosive, volatile, flammable, and toxic fluids, even with solid particles and high viscosity.

Air Preheaters (APH)
An air preheater (APH) is a device used to heat air, commonly used in industrial boilers, thermal power plants, and other thermal energy facilities. APH improves the thermal efficiency of the boiler by transferring heat from the flue gas to the air entering the boiler through heat exchange with it.
APH usually consists of a Heat Exchanger with a number of parallel pipes inside the exchanger through which smoke and air flow to allow heat exchange. In APH, the smoke flows on the outside of the heat exchanger and the air flows on the inside so that the heat between the smoke and the air can be transferred through the pipe walls.
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.
