External Gear Pump Model - (FTNXFTBXFTVX)

Fluid Tech Systems proudly offers ROTOFLUID brand External Gear Pumps, including the FTNX/FTBX series, built for heavy-duty flange and foot mounting applications. FTNX/FTB models are optimized for high-pressure performance, featuring double helical finished gears and hardened, ground shafts that minimize axial load and side thrust, improving pump longevity and efficiency. FTBX is a bush bearing type pump, ideal for viscous liquids with sufficient lubricating properties, suitable for intermittent duty. FTNX models incorporate needle roller bearings, making them suitable for continuous duty with low-viscosity liquids that have lower lubricating values.

These pumps are available in sizes ranging from 1" to 4". Sizes 1" to 2" feature threaded suction and delivery options and come with either foot or flange mounting, while sizes 3" to 4" have flanged suction and delivery and are available only with foot mounting. They operate at pressures up to 20 kg/cm², with a flow capacity ranging from 5.0 LPM to 900 LPM. Suitable for handling liquids with viscosity up to 100,000 SSU, these pumps can operate at temperatures up to 200°C.

Frequently Asked Questions

An external gear pump is a type of positive displacement pump that uses two meshing gears to move fluid. One gear is driven (usually by a motor), and it turns the other gear, creating a vacuum that draws fluid into the pump and pushes it out on the discharge side.

An external gear pump works by using two meshing gears to draw fluid in and push it out. As the gears rotate, they create a space on the inlet side that pulls in liquid. This liquid is then carried around the casing in the spaces between the gear teeth and discharged on the outlet side when the gears mesh again.

External gear pumps offer high efficiency, compact size, and the ability to handle a wide range of fluid viscosities. They also provide a smooth, pulse-free flow, making them suitable for precision metering applications. Additionally, they are known for their durability and reliability in demanding industrial environments.

Regular maintenance for an external gear pump primarily involves ensuring proper lubrication, monitoring fluid quality, inspecting for leaks, and replacing worn parts.
