1 Inch Inlet Outlet Aluminum Air-Operated Double Diaphragm Pump, 35 GPM Max, 120 PSI, Industrial Use, PTFE Diaphragms

Engineered for demanding applications, this air-operated double diaphragm pump delivers 35 GPM max flow and handles pressures up to 120 PSI, making it ideal for industrial use in petroleum, chemical, and wastewater sectors. Its 1 inch inlet and outlet ports ensure efficient fluid transfer, while the aluminum housing provides a sturdy, leak-proof, and corrosion-resistant build for long-term durability.

Premium PTFE Diaphragms for Extended Lifespan:

Featuring double PTFE diaphragms, this pump resists harsh chemicals, abrasion, and extreme temperatures (up to 150°F/66°C). The F46 (PTFE) material ensures longevity even when handling waste oil, gasoline, diesel, solvents, and acidic fluids.

High-Performance Air-Operated Design:

• 1 inch FNPT inlet/outlet for seamless fluid transfer.

• inch air inlet with a high-quality glyd ring for double-acting sealing, enhancing air efficiency.

• Low-pulsation stainless steel air valve minimizes downtime and ensures smooth operation.

Built for Tough Industrial Environments:

• Aluminum alloy construction – Lightweight yet rugged for industrial use.

• Bolted, leak-proof design – Prevents fluid loss and withstands high-pressure applications.

• Max head lift: 229.6 ft (70 m) – Suitable for vertical and horizontal fluid transfer.

Wide-Ranging Applications:

This QBY4-25LF46-1inch-35 pump is versatile, handling:

• Petroleum & Fuels (gasoline, diesel, waste oil).

• Chemicals & Solvents (acids, alcohols, detergents).

• Water Treatment & Food Processing (beverages, coatings).

• Mining, Automotive, and Printing Industries.
