FAQs of Air Operated Double Diaphragm Pump:

Q: How do I select the appropriate diaphragm material for my application?

A: Choosing the right diaphragm material depends on the type of fluid you are transferring. For general use, Neoprene is suitable, while Santoprene offers enhanced chemical resistance. PTFE is ideal when handling aggressive chemicals or high temperatures. Assess the compatibility of your fluid with the diaphragm material for optimal performance.

Q: What are the benefits of using an air operated double diaphragm pump for chemical processing?

A: Air operated double diaphragm pumps provide leak-free operation, are corrosion-resistant, and can handle abrasive or viscous fluids. Their ability to run dry, handle solids up to 6 mm, and self-prime makes them especially reliable in chemical processing environments.

Q: Where can I mount or install this pump, and is it suitable for portable use?

A: This pump is designed for both base-mounted and portable use. Its light weight (13-18 kg depending on construction), compact design, and tool-free maintenance make it ideal for installations in chemical plants, water treatment facilities, or for mobile operations.

Q: What is the process for maintaining the double diaphragm pump?

A: Maintenance is straightforward due to the tool-free design. Regularly inspect and replace diaphragms and seals as needed, and clean the air filter/regulator to ensure consistent air supply. The pumps structure is made for quick disassembly and reassembly, minimizing downtime.

Q: When should I use threaded connections versus flanged connections?

A: Threaded connections are preferred for smaller sizes and flexible installations, while flanged connections offer secure, robust attachment for larger pumps or high-pressure applications. Choose based on your setup, required pressure, and ease of maintenance.

Q: What is the maximum particle size the pump can handle during operation?

A: Depending on the model, the pump can manage suspended particles up to 6 mm in diameter. This capability makes it useful for transferring slurries, wastewater, or fluids containing small solids without clogging.

Q: How is the pump powered, and what advantages does this offer over electric pumps?

A: The pump operates on compressed air (2-7 bar) and does not require electrical power, making it safe for hazardous or flammable environments. Its speed and flow rate can be controlled easily by adjusting air supply, offering flexibility and enhanced safety.
