Features
1. This air diaphragm pump features self-priming capabilities without any rotating parts. It can operate effectively in both dry and wet conditions, with a self-priming height of up to 5m and 8m respectively.
2. The sectional design allows for the safe and efficient transfer of two different liquids simultaneously through the double diaphragm system.
3. The pump can be used directly as a submersible pump, powered by air instead of electricity, making it safer and more cost-effective compared to traditional submersible pumps that require motor maintenance.
4. It provides stall-free and ice-free operation, ensuring consistent performance even under challenging conditions.
5. A bolt joint design ensures even sealing pressure for optimal performance and durability.
6. The diaphragm, ball, and ball seat are made from high-quality imported materials, offering longer service life and reliability.
7. Due to its pneumatic motor, it is suitable for use in potentially explosive environments.
8. The pump is capable of handling corrosive, volatile, flammable, and toxic fluids, as well as those with high viscosity or containing particles.
