for solventsfor chemicalsfor liquids

Product information
The LDQ Quova 1500 air-operated double diaphragm pump is designed for high flow applications up to 350 l/min. It offers chemical-resistant materials and configurable housings (PTFE standard, PE 1000 variant) for demanding processes in chemical, semiconductor and surface treatment industries.

Typical applications

• Transfer of highly viscous media
• Handling solvents and additives in large-volume systems
• Use in potentially explosive atmospheres (Zone 2)

Advantages

• High throughput: up to 350 l/min
• Non-icing air valve for long-term process stability
• Low maintenance thanks to individually detachable diaphragms
• ATEX certification suitable for Zone 2
• Full PTFE design available with PE 1000 option for tailored chemical resistance
