LINCOLN
Frequently asked questions
Common questions about LINCOLN from 3G Electric.
What types of fluids can LINCOLN drum pumps handle?
LINCOLN drum pumps are designed for non-corrosive fluids such as lubricating oils, greases, and hydraulic fluids. The seal material in many models is polypropylene (PP), which provides resistance to a range of petroleum-based products. For specific fluid compatibility, refer to the datasheet for the pump model, as maximum fluid temperature (e.g., 120°F for the air drum pump MPN 1952) and viscosity limits vary by unit.
What is the difference between LINCOLN metered and non-metered dispensing nozzles?
LINCOLN metered dispensing nozzles, such as MPN 3867, include an analog flow meter that allows the operator to measure the volume of fluid dispensed, with a maximum flow rate of 4 gpm. Non-metered nozzles, like MPN 740, do not include a meter and are used for simple, unmeasured dispensing at a maximum flow rate of 25 cu in/min. Both are constructed with steel bodies and NPTF connections.
Are LINCOLN pump tube assemblies interchangeable with other brands?
LINCOLN pump tube assemblies, such as MPN 84978 and 84985, are designed to fit LINCOLN drum pumps with specific inlet sizes (e.g., 2 1/8 inches) and discharge connection types (NPTF). While the NPTF thread is a common standard, the tube length and mounting dimensions are specific to LINCOLN pump models. For reliable performance, use LINCOLN tubes with LINCOLN pumps.
What is the maximum flow rate of LINCOLN lever-action hand pumps?
The LINCOLN lever-action hand pump model G400 delivers a maximum flow rate of 1.5 oz per stroke. This pump features a cast iron housing and a steel suction tube, making it suitable for transferring lubricants from drums in low-volume applications. The actual flow rate depends on the fluid viscosity and operator stroke speed.
Can LINCOLN air-operated drum pumps be used with high-viscosity fluids?
LINCOLN air-operated drum pumps, such as the 6:1 ratio model MPN 1952, are designed for medium-viscosity fluids like oils and greases. The pump's maximum flow rate of 12.6 gpm and maximum fluid temperature of 120°F indicate its suitability for typical industrial lubricants. For high-viscosity fluids, consult the pump's datasheet for viscosity limits and consider using a pump with a higher ratio.
