1/2 Inch 57lpm PP Air Operated Double Diaphragm Pump
Stainless Large Flow Diaphragm Pump
The Stainless Large Flow Diaphragm Pump is a type of industrial pump that offers reliable and efficient pumping solutions for various applications. It is specifically designed to handle high-capacity fluid transfer with ease.
This pump is characterized by its ability to handle fluids with high viscosity, solids, and shear-sensitive liquids without causing any damage or altering the fluid's properties. It is capable of operating even in the absence of liquid, allowing for dry-running without any harm to the pump.
The diaphragm structure is a key feature of this pump. It divides the pump chamber into two parts, and compressed air, controlled by a pneumatic valve, drives one diaphragm forward while the other moves backward. This action creates a vacuum or negative pressure in the pump chamber, enabling the pump to suction in the liquid and then expel it through the advancing diaphragm.
Product Advantage:
1.Providing stall-free, ice-free operation
2.Explosion-proof, zero leak, simple operation
3.ldling capability, self suction, No complex control
4.Can transmit the adhesive liquid and large particles
5.low shearing, Not easy to destroy material structure
6.Diversity of material, no rotating parts, applicable to variouserosive situations
7.By changing the air supply to adjust the flow delivery
8.By changing the air pressure to adjust the pump lift
9.Once over-loading, the pump will automatically stop
10.No mechanical seat, easy maintenance, low cost,
Modularization of main valve and air motor. No broken, easy todisassemble and repair.

Industrial Diaphragm Pump Technical Features
- Diaphragm structure: The pneumatic diaphragm pump adopts a diaphragm structure, which divides the pump chamber into two parts. Compressed air, controlled by a pneumatic valve, drives one diaphragm forward while the other moves backward, creating a negative pressure in the pump chamber, sucking in liquid and then expelling it through the advancing diaphragm.
- Self-priming ability: The pneumatic diaphragm pump has self-priming ability and can start automatically when no liquid enters the pump chamber.
- Dry-running capability: Air-operated diaphragm pumps can run without liquid without causing damage to the pump.
- Ability to handle fluids with high solids: Pneumatic diaphragm pumps are capable of handling fluids with high solids, such as sewage treatment, waste water treatment, chemical delivery, etc.
- Easy maintenance: The pneumatic diaphragm pump has a simple structure, long service life, and easy maintenance and maintenance.
- Energy-saving and efficient: Air-operated diaphragm pumps use compressed air as a power source, which consumes less energy and is more efficient than other types of pumps.
- Safe and reliable: Pneumatic diaphragm pump does not require electrical equipment, and will not produce sparks, explosions and other dangers when used, so it is safe and reliable in flammable and explosive occasions.
- Low cost: Pneumatic diaphragm pump does not require special electrical equipment and control system, the cost is relatively low, and it is suitable for various fluid delivery occasions.
