1/2" DIAPHRAGM PUMP - Lincoln Industrial

The Lincoln Industrial 85623 1/2" Diaphragm Pump is a robust, air-operated solution engineered for reliable and efficient fluid transfer in demanding automotive and industrial environments. Designed with a double diaphragm self-priming mechanism, this pump excels at handling a wide array of liquids, from thin solvents to highly viscous or abrasive materials, without compromising integrity or performance. Its professional-grade construction ensures consistent operation and long-term durability for critical applications.

Key Features

• Air-Operated Design: Utilizes compressed air, eliminating electrical hazards and making it intrinsically safe for use with flammable or explosive materials.
• Versatile Fluid Compatibility: Constructed with a polypropylene pump body and PTFE wetted parts, enabling the transfer of corrosive chemicals, abrasive slurries, and shear-sensitive fluids.
• Self-Priming and Run-Dry Capability: Efficiently primes under most suction lift conditions and can operate dry without sustaining damage, ensuring continuous operation and reduced downtime.
• Variable Flow Control: Easily adjust fluid output by regulating the inlet air supply, offering precise control for various tasks.
• Deadhead Protection: Safely deadheads against a closed discharge without damage, eliminating the need for bypass systems or relief valves.
• Robust Construction: Engineered for heavy-duty use, capable of pumping heavy or solids-laden materials with low internal velocities to prevent damage.

Applications

The Lincoln Industrial 85623 diaphragm pump is an indispensable tool across numerous professional settings. It is ideally suited for transferring new oil and antifreeze in automotive service shops. In industrial sectors, its chemical resistance and robust build make it perfect for critical tasks such as handling abrasive, corrosive, and dangerous fluids in chemical processing, as well as managing water and wastewater treatment. Furthermore, it can be effectively used for transferring various materials including oils, solvents, adhesives, greases, coatings, plastisols, and inks, providing a versatile solution for general fluid transfer needs in manufacturing and maintenance operations.
