Our External Gear Pumps are engineered to provide smooth, consistent, and efficient fluid transfer in both hydraulic and industrial settings. Featuring precision-crafted meshing gears, these pumps create strong suction at the inlet, ensuring continuous and reliable movement of oils, fuels, chemicals, and lubricants. Celebrated for their sturdy construction, low maintenance requirements, and extended service life, they are perfectly suited for industries such as manufacturing, oil & gas, chemical processing, and hydraulic systems.
Fluid Tech Systems proudly supplies the ROTOFLUID brand of External Gear Pumps, including the FTNX and FTBX series, engineered for heavy-duty flange and foot mounting configurations. The FTNX/FTB models are designed for high-pressure applications, featuring double helical finished gears and hardened, ground shafts that reduce axial load and side thrust—enhancing both operational efficiency and pump lifespan. The FTBX variant is a bush bearing type pump, ideal for handling viscous fluids with adequate lubricating properties, making it suitable for intermittent duty cycles. In contrast, FTNX models are equipped with needle roller bearings, making them well-suited for continuous duty with low-viscosity liquids that offer limited lubrication.
These pumps are available in sizes ranging from 1" to 4". Models from 1" to 2" offer threaded suction and delivery connections and are available with either foot or flange mounting. Sizes from 3" to 4" feature flanged suction and delivery ports and are offered exclusively with foot mounting. Designed to operate at pressures up to 20 kg/cm², these pumps deliver flow rates between 5.0 LPM and 900 LPM. Capable of handling fluids with viscosities up to 100,000 SSU, they can perform reliably at temperatures reaching 200°C.

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.
