VEVOR Air-Operated Double Diaphragm Pump 1 inch Inlet Outlet Aluminum 35 GPM Max 120PSI, Nitrile Diaphragm, QBY4-25L-1inch-35

What is VEVOR Air-Operated Double Diaphragm Pump 1 inch Inlet Outlet Aluminum 35 GPM Max 120PSI, Nitrile Diaphragm, QBY4-25L-1inch-35?

The VEVOR Air-Operated Double Diaphragm Pump is a rugged, pneumatic fluid transfer solution built for demanding industrial and automotive environments. Constructed with a lightweight aluminum alloy body and nitrile diaphragms, this 1-inch inlet/outlet pump handles up to 35 gallons per minute with a maximum pressure of 120 PSI. Designed for reliability, it operates without electricity, making it safe for use with flammable or corrosive liquids. The QBY4-25L-1inch-35 model is engineered for self-priming performance, capable of dry lift up to 10 feet and wet lift up to 15 feet, ensuring efficient transfer even from low-level containers.

Key features

• Aluminum Alloy Body — Lightweight yet durable construction resists corrosion and wear.
• Nitrile Diaphragm — Resistant to oils, fuels, and many solvents for broad chemical compatibility.
• 1-Inch NPT Ports — Standardized inlet and outlet size for easy integration into existing systems.
• Air-Operated Design — Uses compressed air to drive fluid transfer, eliminating electrical hazards.
• Sealed Ball Valves — Prevents leakage and ensures consistent flow control.
• Self-Priming Capability — Draws fluid from below source level, up to 15 ft when wet primed.
• Handles Solids Up to 3 mm — Can transfer fluids with small suspended particles without clogging.

Who is VEVOR Air-Operated Double Diaphragm Pump 1 inch Inlet Outlet Aluminum 35 GPM Max 120PSI, Nitrile Diaphragm, QBY4-25L-1inch-35 for?

This pump is designed for mechanics, industrial maintenance teams, and manufacturing operators who need a reliable, explosion-proof method for transferring viscous or aggressive fluids. It’s ideal for use in auto repair shops, paint booths, chemical processing, and wastewater handling where electrical pumps pose safety risks. DIYers with access to compressed air and intermediate mechanical knowledge can also benefit from its plug-and-play operation.

How does VEVOR Air-Operated Double Diaphragm Pump 1 inch Inlet Outlet Aluminum 35 GPM Max 120PSI, Nitrile Diaphragm, QBY4-25L-1inch-35 compare?

Compared to electric centrifugal pumps, this air-operated diaphragm pump offers safer operation in volatile environments and handles thicker, abrasive fluids more effectively. It outperforms smaller 1/2-inch diaphragm pumps in flow rate and solids handling, while its aluminum body strikes a balance between weight and durability. Unlike plastic-bodied AODD pumps, it withstands higher temperatures and mechanical stress, though it may be less resistant to strong acids than stainless steel models.
