Lincoln 85627 Pneumatic Diaphragm Pump 1″ Inlet/Outlet 45 GPM 125 PSI

Description

Product Overview

The Lincoln 85627 pneumatic diaphragm pump is engineered for demanding industrial environments where reliable material transfer is essential. Constructed from high‑grade aluminum, the pump offers an excellent balance of strength and weight, reducing fatigue during installation and maintenance while resisting corrosion from harsh chemicals. Its 1‑inch inlet and outlet ports are sized to minimize flow restriction, allowing the pump to achieve a maximum flow rate of 45 gallons per minute (GPM) and a peak pressure of 125 pounds per square inch (PSI). The diaphragm design creates a sealed chamber that isolates the moving parts from the pumped media, making it ideal for handling oil, antifreeze, and a variety of viscous or solid‑laden substances without risk of leakage.

Key specifications include a compact footprint of 13 × 12 × 12 inches and a weight of just 16 pounds, facilitating easy integration into existing systems. The pump operates on low‑interval velocity principles, which means the diaphragm moves more slowly during each cycle, reducing wear and extending service life. This design also contributes to smoother operation, lower noise levels, and decreased energy consumption compared with high‑speed alternatives. The pump is compatible with standard pneumatic air supplies ranging from 80 to 120 PSI, providing flexibility for a wide range of plant air systems.

Usage

Designed for versatility, the Lincoln 85627 pump excels in a variety of applications across manufacturing, automotive service, and chemical processing facilities. Its ability to handle both liquids and semi‑solid mixtures makes it a go‑to solution for coolant recirculation, oil transfer, and antifreeze distribution in large‑scale cooling systems. The pump’s robust construction also tolerates abrasive particles, allowing it to be used in slurry handling, paint mixing, and waste‑oil reclamation processes where other pumps might suffer premature failure.

Installation is straightforward thanks to the pump’s modular design. The 1‑inch inlet and outlet connect easily to standard hose fittings, and the pump can be mounted on a bench, a frame, or directly onto a production line. Operators benefit from the pump’s low‑maintenance diaphragm, which can be inspected and replaced without disassembling the entire unit. The pump’s low‑interval velocity operation reduces the frequency of diaphragm replacement, further lowering total cost of ownership.

Because the pump runs on compressed air, it can be powered in locations where electricity is limited or where spark‑free operation is required for safety. This makes the Lincoln 85627 an excellent choice for hazardous environments such as fuel stations, chemical plants, and marine applications where electrical equipment could pose a risk.

FAQ

What types of fluids can the Lincoln 85627 pump handle?

The pump is suitable for a wide range of fluids, including oils, antifreeze, coolant, paint, slurry, and other viscous or solid‑laden materials. Its diaphragm design isolates the pump internals from the media, preventing contamination and leakage.

Can the pump be used with standard air compressors?

Yes. The Lincoln 85627 operates efficiently with air supplies between 80 and 120 PSI, which are common specifications for most industrial compressors. This flexibility allows easy integration into existing pneumatic systems.

How often does the diaphragm need to be replaced?

Thanks to the low‑interval velocity operation, the diaphragm experiences reduced wear compared with high‑speed pumps. In typical industrial use, the diaphragm can last several years before replacement is required, and it can be serviced without dismantling the entire pump.

Is the pump suitable for hazardous environments?

Because the pump is powered by compressed air rather than electricity, it is inherently spark‑free, making it safe for use in flammable or explosive atmospheres such as fuel stations or chemical processing plants.

What warranty does Lincoln Automotive provide?

Lincoln Automotive offers a limited warranty that covers any manufacturing defects for a period of one year from the date of purchase. This warranty, combined with our technical support team, ensures you receive reliable assistance throughout the product’s lifecycle.
