Features
1. The air-operated diaphragm pump features self-priming capabilities without rotating parts, allowing for both dry and wet priming with a maximum height of 5m and 8m respectively.
2. Its sectional design enables the transfer of two different liquids simultaneously using a dual-diaphragm system.
3. This pump can function as a submersible pump, powered by air, eliminating the risk of leaks and other safety issues. Compared to traditional submersible pumps, it is more cost-effective due to reduced motor maintenance.
4. The pump body is available in materials such as PVDF and PP, while the diaphragm can be made from Teflon, rubber, or wear-resistant materials.
