Introduction
The QBK series air-operated diaphragm pump is a reliable and efficient solution for transferring liquids in various industrial applications. Powered by compressed air, this positive displacement pump uses the movement of diaphragms on both sides to create a pumping action. Designed with high-performance materials, it offers excellent corrosion resistance and durability. The pump is compatible with GRACO/HUSKEY models, making it easy to replace internal components. It is widely used in the chemical industry as a submersible pump due to its safety and lack of electrical requirements.

1. This air-operated diaphragm pump features self-priming capabilities without rotating parts, allowing it to handle both dry and wet priming with self-priming heights up to 5m and 8m respectively.
2. Its sectional design enables the transfer of two different liquids using a dual-diaphragm system.
3. The pump can be used directly as a submersible pump, powered by air, eliminating leakage risks and offering a safer alternative to electric pumps.
4. The pump body is constructed from PVDF or PP, while the diaphragm is made from Teflon, rubber, or wear-resistant materials.
Application
1. Chemical Industry: Ideal for handling emulsions, slurry, abrasive materials, corrosive substances, and highly acidic or basic media.
2. Marine Industry: Used for cleaning oil tanks and barges, transporting high-temperature liquids (up to 150°C).
3. Ceramic Industry: Suitable for glaze slurries used in tiles, porcelain, bricks, and pottery.
4. Environmental Protection: Can be paired with plate-and-frame filter presses for wastewater treatment applications.
