Introdução ao produto
The BFQ Series air operated double diaphragm pump is a pneumatic double-diaphragm pump designed for diverse industrial fluid transfer applications. Powered by compressed air, it achieves stable operation through the reciprocating deformation of its diaphragms, offering high stability, extended service life, low noise, minimal vibration, and excellent clog resistance. Its precision construction not only handles routine fluid transfer but also effectively processes high-viscosity, abrasive, and corrosive sensitive fluid.
BFQ air operated diaphragm pumps can be manufactured using various materials, including stainless steel, polypropylene, and polyvinylidene fluoride. They are suitable for chemical processing, wastewater treatment, coatings, mining, and other harsh operating environments. Their seal-less, zero-leakage design ensures reliable handling of volatile, toxic, or corrosive fluids. We offer custom features to meet specific flow, pressure, and temperature requirements for diverse applications.
Princípio de funcionamento
- Air supply activation: Compressed air enters the diaphragm pump through the air inlet and is directed by the air distribution valve to one side of the air chamber, initiating the pumping cycle.
- Diaphragm movement: Air pressure pushes the diaphragm outward, while the connecting rod drives the opposite diaphragm to move synchronously.
- Chamber volume change: One pumping chamber decreases in volume (discharge stroke) as the opposite chamber expands in volume (suction stroke).
- Check valve operation: During the suction stroke, the inlet check valve opens and draws fluid into the chamber, while the outlet valve remains closed to prevent backflow.
- Automatic air switching: When the diaphragm reaches its stroke limit, the air valve automatically shifts, redirecting compressed air to the opposite air chamber.
- Discharge stroke: The chamber that previously expanded now contracts, opening the outlet check valve and discharging the fluid into the pipeline.
- Continuous reciprocation: This alternating suction and discharge cycle repeats continuously, producing a stable and reliable fluid flow without the need for electrical power.

Features of Air Operated Double Diaphragm Pump
- No priming required, with a maximum self-priming height of 5.48 meters and a head of 84 meters.
- Excelente desempenho de passagem, permitindo a passagem de partículas até 2,5 mm de diâmetro. Desgaste mínimo da bomba aquando da bombagem de lamas ou impurezas.
- Diaphragm completely isolates pumped media from moving parts, preventing external leakage. When handling toxic, volatile, or corrosive media, it avoids environmental contamination and personal safety hazards.
- Não necessita de eletricidade, garantindo um funcionamento seguro e fiável em ambientes inflamáveis ou explosivos.
- Easy operation and reliable performance. Starting and stopping requires only opening and closing the air supply valve. No damage occurs during dry running or sudden shutdowns. Self-protection feature automatically stops the pump during overload and restarts when load returns to normal.
- This pump requires no oil lubrication. Dry running has no adverse effect on the pump.
